[[caption-width-right:300:Creator/ClorisLeachman was part of the main cast in all but billing.]]
%%
An actor who is, to all outward observation, a member of the regular cast, but who still receives guest billing. This usually has something to do with their contract and whether or not it stipulates that they receive main cast billing (and possibly with how much they get paid), though in some cases, it may be done as a gimmick to call attention to an actor whose reputation vastly exceeds that of the rest of the cast.

This can also happen if a guest star becomes an EnsembleDarkhorse and is written into future episodes to capitalize on their unexpected popularity, which may eventually lead to a PromotionToOpeningTitles. Other times, however, they remain guest stars due to difficulties modifying the opening titles.

Often with many cases exclusivity can have an effect. If a cast member is a regular, then that show has them somewhat "locked down," and they have to stay at the cost of other projects. However, if they're merely a "guest star," that can often give them the freedom to work on other projects if they want to.

Occasionally, you even see a "Special Guest Star" credit on a ''movie''. How exactly someone can "guest star" in a production that doesn't have a regular cast is left as an exercise to the reader.

Compare AdvertisedExtra, where a character who is supposed to be part of the main cast ends up feeling like a guest star. Also, compare AwardCategoryFraud and "AndStarring."

[[folder:Film]]
* ''Film/Plan9FromOuterSpace'' has Creator/BelaLugosi, John Breckinridge, and Lyle Talbot listed as "Guest Stars".
-->'''[[Podcast/RiffTrax Bill Corbett]]:''' ''How do you guest star in a movie!?''
* Creator/ColemanFrancis did this twice.
** ''Film/RedZoneCuba'' boasted Creator/JohnCarradine as a "Guest Star".
** ''Film/TheBeastOfYuccaFlats'' boasted Creator/TorJohnson as a "Guest Star".
* The 1984 comedy ''Best Defense'' includes this widely-visible text in the poster: ''Creator/DudleyMoore. Strategic Guest Star: Creator/EddieMurphy.'' There is a reason for this - the film originally did not feature Murphy, but when the original cut tested poorly they filmed scenes with him and inserted them into the film.
[[/folder]]

[[folder:Live-Action TV]]
* ''Series/DoctorWho'':
** In Season 8 of the classic series, the Roger Delgado Master was treated as a guest star despite appearing in (and dominating) every episode of the season bar the first episode of "The Mind of Evil" and the first half of "Colony in Space". The same thing happened in Season 23 with the Valeyard (and the Inquisitor).
** The [[Recap/DoctorWhoTVMTheTVMovie TV movie]] credited Creator/EricRoberts, who played The Master, as a guest star, probably because it was intended as the pilot to a new TV series, but said show failed to materialize.
** During the Ninth Doctor's tenure, only Creator/ChristopherEccleston and Creator/BilliePiper's names were featured in the title card. Despite Jack Harkness being a second companion during the last five episodes, Creator/JohnBarrowman's name isn't included in the opening credits. He wouldn't get main credits billing until he returned for the Master story in series 3.
** This was the case for Creator/NoelClarke as Mickey Smith, and most noticeable in series 2, where he actually travels with the Doctor and Rose from "School Reunion" through the end of the Cybermen two-parter, but only Creator/DavidTennant and Creator/BilliePiper's names are in the opening credits.
** Creator/ArthurDarvill was recurring often enough to appear to be a regular from the start of the Eleventh Doctor's tenure at the start of series 5, but remained a guest star until he was ''finally'' [[PromotionToOpeningTitles promoted to the opening titles]] in series 6.
** An aversion, at least on screen: Creator/WilliamHartnell's last story as the actual star of ''Doctor Who'' was [[Recap/DoctorWhoS4E1TheSmugglers "The Smugglers"]]. For the First Doctor's final adventure, [[Recap/DoctorWhoS4E2TheTenthPlanet "The Tenth Planet"]], recorded at the start of a new production block with his replacement in the wings, Hartnell was contracted as a guest artiste. His on-screen billing, however, remained the same.
* ''Series/TheAmericans'' has Richard Thomas playing Frank Gaad, Stan Beeman's supervisor at the FBI. Nearly 2 seasons in and Thomas has appeared in every episode of the series except one. Keidrich Sellati and Holly Taylor, who play the Jennings children, have appeared in fewer episodes, despite being main cast members.
* ''Series/{{Bosch}}'': A fair number of the cop characters at Hollywood Division get focus and major roles in the stories, but only Creator/TitusWelliver, Jamie Hector, Amy Aquino, Creator/MadisonLintz, and Creator/LanceReddick get main credits billing.
** This applies at Hollywood Division to Gregory Scott Cummins and Troy Evans ([[ThoseTwoGuys Crate and Barrel]]) on a show-length basis.
** [=DaJuan=] Johnson (Rondell Pierce) and Paul Calderon (Jimmy Robertson) are also big offenders. This is most notable in season 4's adaptation of ''Literature/AngelsFlight'', where they're in every episode as members of the Elias task force. The same is true in season 4 for Creator/WinterAveZoli, who plays Amy Snyder.
** Creator/MimiRogers as Honey Chandler gets this during the fifth season (when Bosch retains her to help defend himself against Preston Borders' accusations of evidence tampering) and sixth season (where Bosch's daughter is interning at her firm).
* ''Series/{{Bonanza}}'': Done once, in 1972's "The Lonely Man" for regular cast member Victor Seng Yung, who played Hop Sing, who was a regular and appeared in 80 percent of the episodes. This was the only episode where Hop Sing -- who falls in love with a white woman (in an episode about unjust interracial marriage laws) -- is the primary character.
* ''Series/BlueBloods'' does this to a good part of the cast (Jack & Sean, Garrett, Baker, Jackie, Eddie, Baez, and Sid). To be fair, the opening sequence is about 20-30 seconds long.
* ''Series/LittleHouseOnThePrairie'': This was done occasionally with regular cast members (outside of those playing the original Ingalls family) credited as guest stars for episodes in which they were the main focus. Some examples: Season 6's "Second Spring" (with Richard Bull and Katherine [=MacGregor=] promoted to "Special Guest Star" status) and Season 8's "A Promise to Keep" (Victor French, who had just rejoined the cast).
* ''Series/SharonLoisAndBramsElephantShow'' always had Eric Nagler listed as a guest star despite long runs of episodes in which he continuously appeared.
* ''Series/SaturdayNightLive'' has always had two "categories" that players appeared in, "repertory" players and "featured" players,[[note]]"Featured Players" were formally introduced for season 5 in 1979, but even before then, the show had performers who appeared frequently but weren't part of the cast, like Michael O'Donoghue, George Coe, Don Novello and the team of Al Franken and Tom Davis[[/note]] excepting a couple of seasons in the Dick Ebersol era which saw a smaller overall cast and greater use of variety acts. The repertory cast, for years, was considered the "main" cast, and all the other players were there to supplement the main cast. Starting at about season 16, the line between featured player and repertory player began to blur, to the point that by season 38, the only real difference between a "featured" player and the main cast is how they're billed. New players always spend at least one season (usually two) being billed as "featuring" and then get moved up. This is a change from seasons 1--23 wherein new players intended to be used regularly would always be moved straight to the main cast. Ana Gasteyer and Tracy Morgan were the last players that this happened to; everyone hired since has spent at least a season as a featured player (with the exception of Creator/AmyPoehler, who was introduced as a featured player, but was promoted to the repertory cast later in her first season).
** In season 42, Creator/AlecBaldwin appeared in more than half the episodes as Creator/DonaldTrump, so in the eyes of the Emmy Awards he was considered a cast member and was nominated in the comedy Supporting Actor category (which he won).
* On ''Series/{{Community}}'':
** Creator/JimRash is listed as a guest star in the first two seasons although he appears in almost every episode and often drives the plot. (He had the first lines of dialogue in the Pilot) He eventually made it to the titles in season 3.
** Creator/JonathanBanks is only listed as a guest star in season 5 although he appears in every episode except for the season premiere, which is focused on rebooting the series with (most of) the original cast and the fourth episode, which was a bottle episode revolving around Pierce's death.
** Creator/PagetBrewster and Creator/KeithDavid are only credited as guest stars in season 6, though they appear in most of the episodes (in Brewster's case, all 13 episodes of the season; David appeared in all but the premiere).
* ''Series/{{Angel}}'':
** Andy Hallett, the actor who played Lorne, was listed as a guest star or special guest star until the late 4th season, despite appearing in all but a handful of episodes since his debut in Season 2, Episode 1.
** Stephanie Romanov, who played Lilah Morgan, appears in 35 episodes, more than some of the regulars, including 13 episodes of Season 3, and is one of the few people who appear in all of the first four seasons, but remains a guest star.
* [[Series/BattlestarGalactica1978 Both]] [[Series/BattlestarGalactica2003 incarnations]] of ''Battlestar Galactica'' have a veritable parade of "guest stars" who've appeared in almost every episode.
** The new series upped the ante by listing some actors ''before'' guest stars but without a "Guest Starring" credit, leaving them in some strange netherworld between "guest star" and "regular". Actors listed this way included Helo, Cally, Dee, Gaeta, Billy, Sam, Tyrol, Crashdown and Tigh -- who may just be the Most Triumphant Example of this trope, as Creator/MichaelHogan appears in more episodes than most of the actors who are ''actually in the opening credits''.
* ''Series/TheBobNewhartShow'': Creator/BobNewhart and Creator/SuzannePleshette, who play Bob and Emily Hartley, are the only actors whose credits come at the start of the show. Creator/BillDaily (neighbor Howard Borden), Creator/PeterBonerz (dentist Jerry Robinson), and Creator/MarciaWallace (SassySecretary Carol Kester) all have credits at the end of the show, just before the other guest stars. Creator/JackRiley, whose Elliot Carlin is the most frequently seen patient, may also count as a fake guest star.
* An odd example with Creator/DanielleFishel as Topanga on ''Series/BoyMeetsWorld''. She doesn't appear till the 4th episode and appears in very few for the next handful of episodes. By mid season onward she gets a significant amount of screen time equal or more than Lee Noris as Minkus who receives top billing while Fishel is relegated to guest star. Ironically she finally received top billing in season 2, but has significantly less screen time, with only a few early episode feature her getting any significant focus after that she has very little to do with any of the story-lines. By season 3 she becomes Cory's girlfriend and settles into being part of the main cast.
* ''Series/GameOfThrones'':
** Creator/JasonMomoa, who played the not-at-all insubstantial role of Khal Drogo, was never credited in the opening titles of the first season, despite his character out-living several starring characters. Instead, his name appears at the end of guest star credits in the ending credits of each episode with an "Also Starring" attached to it. This was purportedly because Momoa wanted an "AndStarring" credit, which would put him on equal billing with Creator/PeterDinklage -- despite the fact that his character was written out at the end of Season 1, while Tyrion Lannister has gone on to be the protagonist (insofar as the EnsembleCast with ThreeLinesSomeWaiting ''has'' one) and Dinklage received first billing in place of DecoyProtagonist Creator/SeanBean. (This was also Momoa's breakout role; while he might have had the clout to demand such billing ''after'' the season ended, he didn't when it started.) The compromise was for Momoa to get the "Also Starring" in the guest credits instead.
** Neither Creator/JulianGlover (Pycelle) nor Creator/ConlethHill (Varys) are credited as regulars in the first season, even though they are arguably as important, and appear just as often, as regular Aiden Gillen (Littlefinger). And for that matter, Julian Glover never got the PromotionToOpeningTitles, even though his character outlived a lot of those credited as regulars.
** In Season 2, Creator/DonaldSumpter (Luwin), Creator/JoeDempsie (Gendry), Creator/GwendolineChristie (Brienne), Music/NataliaTena (Osha), and Tom Wlaschiha (Jaqen H'ghar) are all credited as guests even though they appear as often as several characters credited as regulars. Two of them even survive the SeriesFinale!
** Roose Bolton's actor is only billed as a guest star from Seasons 2-4 despite Roose being one of Robb's top lieutenants and eventually TheStarscream. He eventually gets the PromotionToOpeningTitles starting Season 5 [[spoiler: which doesn't last long because he dies early in Season 6]].
* Creator/JohnGlover, who played the Devil on every episode of Fox's short-lived ''Series/{{Brimstone}}'', was always credited as a guest star. In fact, the only name in the opening titles was Peter Horton.
* ''Series/BuffyTheVampireSlayer'':
** Creator/AnthonyStewartHead (Giles) got this treatment after he rejoined the cast for the final season, though he was billed as a Super-Duper Extra Special Guest Star to compensate.
** Creator/AmberBenson (Tara) in all but her final appearance, despite appearing in almost 50 episodes. She only got billing as a main in her last appearance because Creator/JossWhedon wanted to [[spoiler:kill off someone]] in the first episode that they got their name in the main titles. Joss originally wished to do this with Xander's friend Jesse in the pilot episode, but financial restrictions did not allow for it.
** Creator/ElizaDushku (Faith) appeared in a key role in over half the third season episodes yet never got billing beyond "guest star".
** Creator/EmmaCaulfield (Anya) appears in ''15'' out of season 4's ''22'' episodes. They got the hint and she received a PromotionToOpeningTitles in the next season.
** In Season 7, Creator/TomLenk (Andrew) is in 15 of the 22 episodes and both Creator/DBWoodside (Robin Wood) and Creator/IyariLimon (Kennedy) are in 13 (Lenk and Limon are in every episode in the second half of the season), with all three of them getting at least one ADayInTheLimelight episode. They're listed as guest stars.
** Creator/KristineSutherland (Joyce) appears in more episodes than most of the regulars, including 15 episodes of Season 3 and all bar one of the episodes prior to [[spoiler: her death]] in Season 5, but never made it past "guest star".[[note]]Incidentally, Joyce is also the sole recurring character to appear in all seven seasons; the only other characters to appear in every season are Buffy, Willow, Xander, and Giles.[[/note]]
** Less dramatically, Creator/AlexisDenisof (Wesley) appears in over a third of the episodes in the third season, not missing an episode after his debut and often getting more screen-time than the regulars. He would be rewarded with a regular role on SpinOff show ''{{Series/Angel}}'' the following year.
* The third season of ''Series/{{Bugs}}'' used the same opening titles as the second, meaning only Craig [=McLachlan=], Jaye Griffiths and Jesse Birdsall were credited. Jan Harvey was given a special credit at the start of each episode (and, strangely, Leslie Ash was accorded [[BillingDisplacement the same honour]] for the first two episodes as well as [[AdvertisedExtra appearing in the season's publicity photos]]), but Paula Hunt as new team member Alex was simply listed on the closing credits, despite appearing in every episode. Harvey and Hunt were PromotedToOpeningTitles on the fourth season.
* ''Series/{{Cheers}}'':
** Creator/JohnRatzenberger appeared as Cliff Clavin in nearly every episode of the first season (the sole exception being the fourth episode, "Sam at Eleven"), but wasn't in the opening credits until season 2.
** In the final few seasons, Paul appears in nearly every episode, usually seen sitting near Norm and Cliff and often having speaking roles. Yet, he is never added to the opening credits. In fact, he appears in more Season 11 episodes than Lilith, who remained in the opening credits (though, only for the episodes she appeared in).
* The only actors on the opening titles of ''Series/CrimeTraveller'' were Michael French and Chloe Annette, with Sue Johnson getting an extra credit post-titles. Despite this, Paul Trussell and Richard Dempsey as the other members of CID appear in every episode and Bob Goody as caretaker Danny only missed one.
* ''Series/TheDickVanDykeShow'' has a couple, most notably Richard Deacon as Mel Cooley, who has appeared in more than half of all episodes on the show. The Helpers were also fake guest stars, which meant that Creator/AnnGuilbert had a more flexible schedule as a mother of young children and Creator/JerryParis could disappear behind the camera more often.
* ''Series/Drive2007'' listed Dylan Baker as a guest star for five of its six episodes. He was finally moved to the opening credits for the finale. Oddly, Creator/RochelleAytes, Creator/RileySmith, and Mircea Monroe were not in all six episodes, but were listed in the opening credits.
* Creator/TimCurry as [[spoiler: the main antagonist]] of ''Series/{{Earth 2}}'' is [[NarrowedItDownToTheGuyIRecognize given away]] [[LargeHam by his performance]] and billing, despite being in more episodes than some of the regulars (also not helped when the show was cancelled).
* ''Series/{{ER}}'' is a frequent offender, since it had such a large cast and they had to draw the line somewhere. In consequence, many regular nurses and receptionists who appear in every episode receive guest star billing.
** Of particular note are Laura Ceron (Chuny) and Deezer D (Malik), who each have been in more episodes than everyone except Creator/NoahWyle and Laura Innes, but all their appearances were under normal guest star billing.
* Frank Dekova appeared in every episode of ''Series/FTroop'' save one from the show's first season as Chief Wild Eagle, the grumpy and grizzled but goodnatured leader of the pacifistic Hekawis tribe. The producers felt he was such an important part of the show [[PromotionToOpeningTitles that he was added to the credits for the second season.]]
* Jool, Noranti, and Sikozu on ''Series/{{Farscape}}''. Actresses Melissa Jaffer and Raelee Hill, who played Noranti and Sikozu respectively, were credited as guest stars even in the small handful of Season 4 episodes they didn't appear in.
** Not to mention Jonathan Hardy, though this is somewhat justified in that he was only a voice actor. Still, he appeared in every single episode of the show.
** An interesting version is Lani Tupu. He was credited in the main cast in Season 3, where he was a regular cast member, but (if memory serves) never as a guest star, even in episodes he guest starred in as Captain Bailar Crais. The kicker? He's in nearly every episode (if not every episode) as the voice of Pilot. The latter role is credited in the ending credits.
* ''Series/FlashGordon2007'' listed Jonathan Lloyd Walker, who played Rankol, as a guest star, even though he was in every episode (albeit only via stock footage in the ClipShow), meaning he appeared more than Jody Racicot (Zarkov) and Creator/JohnRalston (Ming) who were on the opening titles.
* ''Series/{{Frasier}}'': Dan Butler played Bulldog, and appeared in nearly every episode for the first few years as a guest. During the latter years, he was moved to the opening cast credits -- but appeared in very few actual episodes because Butler was touring with his one man show ''The Worst Thing You Could Have Ever Told Me''.
* Busy Phillips was credited as "Also starring" following the main credits of ''Series/FreaksAndGeeks'' throughout the series' run, but she gets just as much screen time and dialogue as any of the actors featured in the opening sequence. One of the DVD commentaries states that Kim Kelly was intended to be a minor character, but the creators ended up liking her too much to not keep her around. It's likely she would have been added to the main credits if the show hadn't been cancelled after one season.
* Edward Herrmann is listed as "Special appearance by" in the TitleSequence of ''Series/GilmoreGirls'' despite being in nearly every episode. This meant that he was listed as “Special appearance by” even in episodes where he ''didn't'' appear.
* Aaron Hill as "Beaver" and Derek Mio as "Wade" on ''Series/{{Greek}}''. As Kappa Tau's right and left hand men, both were relegated to "Also Starring" in the end credits until Chapter 3, when they were Promoted To...the guest star list.
* It took until the second season of ''Series/HappyDays'' before Henry Winkler (Fonzie) and Don Most (Ralph Malph) were credited in the opening theme, despite Fonzie appearing in every episode, and Ralph missing only one episode in the first season. In the former's case, this could be due to the fact that Fonzie was originally intended as just a side character.
* ''Series/{{Heartbeat}}'' ended up with an extensive ensemble cast and sometimes had as many as 13 actors on the opening titles...but Claire Calbraith, who was on the show for two years as Tricia Summerbee and was effectively the female lead on Season 11 and the first half of Season 12 was never given the honour. (Curiously, soon after she left, several more minor characters were added on, as if they'd been waiting for her to go before putting them on.)
* ''Series/{{Heroes}}'' has several, but the only recurring characters to be promoted are HRG in season 1, Sylar and Ando in season 2, Angela in season 3, and Samuel in season 4. Important characters who were ''not'' promoted include Sandra, the Haitian, West, Daphne, Knox, and many more. Indeed, season 3 ''demoted'' several characters - and one of them, Elle, has grown to being a true fake special guest star.
* ''Series/HomeAndAway'' has many examples. Most notable are Sam Holden, Melody Jones, and Angelo Rosetta who appear just as much as the regulars and have several major storylines.
** This appears to be the exception, as although they're involved in major storylines, none of them have had anywhere near as much screen time as the regulars.
** Morag Bellingham's actress had a special contract allowing her to come and go from the show as she pleased, which is why she was never credited as a main star.
** Angelo's now a regular.
** Given regular characters only appear in two or three episodes out of five in each week anyway, most of these do actually appear as much as the regulars. Melody was set up as a new foster child and considered a regular by many, so her sudden decision to go back to her evil mother who apparently wasn't evil anymore, just a few weeks into a new season and having just had two episodes to herself, was a bit of a shock.
** However, characters like Sam and Angelo did have a story arc to follow which ended in them leaving the bay (in a body bag and police car, respectively). They weren't intended to stay for very long.
** Angelo returned just three months after his apparent exit, was rapidly PromotedToOpeningTitles and stuck around for another two years.
** Stacey Macklin was a curious case in the early years, she appeared as much as anyone and outlasted several regulars yet was always credited as a guest star.
* Pushed to an extreme in the latter half of the fourth season, and the entire fifth season, of ''Series/{{House}}'', where House's new team of doctors, whom he spends most of his time [[strike:ordering around]] interacting with, are guest stars, whereas two members of his former team, played by Jennifer Morrison and Jesse Spencer, have been relegated to occasional roles but are still billed as regulars. [[JustifiedTrope Justified]] in the first half of the fourth season in that there were far more potential members of the new team than would actually end up on it and revealing which ones were to become regulars would spoil it.
* The TV miniseries/DTV movie series ''Josh Kirby...Time Warrior!'' effectively had two sets of opening credits (one which played as a typical TV series intro, another that was simply the rest of the cast and crew for the movies on a black background, like a regular movie). The TV Show credits played up the roles of Corbin Allred (Josh Kirby), Derek Webster (Dr Zoetrope) and Jennifer Burns (Azabeth Siege), yet Barrie Ingham (Irwin 1138) is relegated to the rest of the cast, spoiling a major plot point.
* ''Series/{{Justified}}'': Creator/WaltonGoggins appeared as Boyd in 9 episodes of the first season's 13, but wasn't promoted to part of the regular cast until season 2.
** This example is somewhat of a [[{{Pun}} *ahem*]] [[JustifiedTrope justified]] one since initially Boyd Crowder was supposed to die in the pilot, just as he does in the short story the series is based on, but was so popular in test screenings that he was SparedByTheAdaptation.
* Dame Thora Hird, Jean Alexander and Dora Bryan made a "Special Guest Appearance" virtually every episode for years on ''Series/LastOfTheSummerWine''. They finally started being listed as members of the regular cast in 2002.
* ''Series/LawAndOrderSpecialVictimsUnit'': Tamara Tunie, who played Medical Examiner Melinda Warner in nearly every episode of seasons 4--6, was always credited as a guest star because of a conflict with her contract for ''Series/AsTheWorldTurns'' which wouldn't allow her to take top billing on any other show. That contract ended in 2007, however, and she was immediately promoted to SVU's opening credits.
* Leslie Hendrix as Medical Examiner Elizabeth Rodgers on ''Series/LawAndOrder'' and ''Series/LawAndOrderCriminalIntent''. She's been on the original series longer than any of the current cast members.
* On ''Series/{{Lost}}'', some recurring characters have appeared more than some members of the main cast, and yet are relegated to guest status. Examples include Tom in season three, who only appeared in one less episode than cast member Claire, and Frank in season four, who has appeared more times than [[spoiler: Michael]] and Desmond, and just as many times as Miles. As of the season 5 finale, [[ReallySevenHundredYearsOld Richard Alpert]] has appeared more than any other guest star, to the point where some confuse him as being a member of the main cast. This may stem from rumors that Richard would join the main cast in season 4, which then repeated themselves prior to season 5, but Richard is still a guest star. ([[PromotionToOpeningTitles Promoted To Opening Credits]] in season 6).
** Nikki and Paulo in season 3 and Daniel, Miles, and Charlotte in season 4 are all credited as guest stars in press releases but as main cast members in the episodes themselves. While this discrepancy was fixed for Daniel and Miles in season 5, the issue persisted with Charlotte...though it didn't matter for long because [[spoiler:she dies five episodes into season 5]].
** Almost every recurring character got a PromotionToOpeningTitles in the series finale.
* Creator/JonathanHarris (Dr. Smith) was billed as a "Special Guest Star" on ''Series/LostInSpace'', despite being a regular member of the cast. This is because he was not added to the show until after the original pilot was produced, and none of the other cast members were willing to renegotiate their contracts for lower billing. To compensate for sticking Harris at the end, the "Special Guest Star" credit was invented to give him featured billing. This was the beginning of the AndStarring custom in credits to put featured players at the end of the list with a special notation.
** According to a documentary on the ''Series/LostInSpace'' 3rd season DVD boxset, Jonathan Harris also got paid more for his "Special Guest Star" status. The studio apparently tried to get him moved into the credits with the others starting at the beginning of season 2, but he refused.
* In the first season of ''Series/MadMen'', Creator/JohnSlattery was credited as a guest star in spite of Roger Sterling's major part in the first season and seasons that would follow. He appears in 10 of the 13 episodes of season 1. Notably, Maggie Siff (Rachel Menken) is a main cast member in season 1 but only appears in 7 episodes.
* Creator/ClorisLeachman was always billed as a special guest star during her time on ''Series/TheMaryTylerMooreShow'', probably due to her Oscar win before the show aired.
* Heather Locklear was billed as "Special Guest Star" for her entire run on ''Series/MelrosePlace,'' despite being the main character for the last several seasons and appearing in all but the first 20 episodes of the show.
** Additionally, Laura Leighton appears in all but two episodes in the second season, though isn't promoted until season three. Also, Creator/MarciaCross appears in every episode (barring one) in season three, though is only upgraded to series regular status in season four. Plus, Patrick Muldoon and Rena Sofer play major roles in the show's fourth and seventh seasons respectively and appear in almost every episode, yet are never given anything above "guest star" billing.
* Creator/MartinLandau appeared in all but two episodes of the first season of ''Series/MissionImpossible'', with his character Rollin Hand being an important part of the IMF team and having a major role in nearly every mission... and each time he was credited as a "Guest Star" or "Special Appearance". The story goes that Landau was wary about committing himself to the series out of fear that he would be unable to appear in other projects at the same time and thus he didn't want to be bound to contract, so he didn't officially join the cast until the second season.
* The opening of ''Series/MurderSheWrote'' only listed Angela Lansbury as a star, and true to that, she's the only person to star in even 20% of the series' episodes. Frequently recurring actors like William Windom, Ron Masak, and Tom Bosley (who each took on major roles when featured) were only billed as part of the ensemble "also starring" roll at each episode's opening. As they were listed in alphabetical order, Windom was often billed last among the episode's actors as a result.
* The series ''Series/MutantX'' had Tom [=McCamus=] as the villainous Mason Eckhart. Despite appearing in every single episode (not to mention the show's title sequence montage) of the first season, he was billed as a guest star.
* Sean Murray appeared in roughly a third of the episodes in season one of ''Series/{{NCIS}}'', and was billed as a guest star. He was promoted to the main cast in season two and has remained there ever since.
** Creator/BrianDietzen has played Jimmy Palmer, ME's assistant, longer than Creator/CoteDePablo, Creator/LaurenHolly and Creator/RockyCarroll have been regular cast members (having been introduced in season 1), but is still relegated to the guest stars' robot roll call. He was credited as a Special Guest Star starting from Season 6 and appeared on the DVD boxset covers (the only person to do so and not be a main cast member at the time) from Season 7. Heck, he's even had whole episodes about him! Which made it all the more heartwarming when he was ''finally'' PromotedToOpeningTitles for the show's tenth season.
* Katya, Will, and Lolly (in her second stint) on ''Series/{{Neighbours}}'' were always credited as guest stars despite being regular characters. Why this was the case for Katya is anyone's guess but the actors playing Will and Lolly left very soon after joining the show, which is probably why they were never promoted.
** Though all three were included in the opening credits, however briefly.
* ''Series/NorthernExposure'': Creator/MoultriePatten as Walt Kupfer. he appeared in nearly every episode in the last couple seasons.
* Jon Gries as Broots in all but the final season of ''Series/ThePretender''.
* ''Series/PrettyLittleLiars'' had Keegan Allen featuring in most episodes as Toby Cavanaugh, a love interest to one of the core four. He never received star billing throughout the seven seasons unlike characters including Mona, Ella, Byron, Ashley and Maya, who had less screen time.
* In ''Series/{{Sanctuary}}'', Ryan Robbins was listed as a guest star for all of season one, despite appearing in thirteen out of fourteen episodes.
* In ''Series/{{Scrubs}}'', at least four guest stars have appeared in over 50 episodes- Creator/ChristaMiller played Jordan in 79, Sam Lloyd played Ted in 83, Aloma Wright was Laverne or Shirley in 90, and Robert Maschio played Todd in 105.
** In season 1, Creator/NeilFlynn isn't considered part of the main cast, even though he appears in every single episode of that season. Ironically, he does get promoted to the main cast in season 2, but doesn't appear in "My Lucky Day", meaning he appeared less in that season than he did in the season where he wasn't part of the main cast.
* Only Creator/BenedictCumberbatch (as Holmes) and Creator/MartinFreeman (as Watson) are credited in the opening titles of ''Series/{{Sherlock}}''. Rupert Graves (Lestrade), Creator/UnaStubbs (Mrs. Hudson), Creator/LouiseBrealey (Molly) and series co-creator/writer Mark Gatiss (Mycroft) appear in every episode of Series 2 and 3 (and all but one episode of the first), and are incredibly important characters, but are still just guest-stars.
* ''Series/{{Smallville}}'' lists Creator/EricaDurance (Lois) as a guest star on Season 4, despite her appearing in over half the episodes. She was PromotedToOpeningTitles on Season 5.
* ''Series/TheSopranos'': Jerry Adler guest-starred as Hesh Rabkin in 27 episodes throughout the course of the series yet never received billing. This was in a series that tended to eventually give in-episode billing to actors in recurring roles.
* ''Series/StargateSG1'': Dr. Janet Fraiser had regular appearances from season 1, Episode 3, until midway through season 7. In season 1, Episode 11, she's standing with SG-1 as the recipients of the US flag during Daniel's military funeral, and her role remains pivotal to both SG-1's military and personal plotlines until season 7. Despite the producers and writers regarding her as a main character, she is never billed as one. [[spoiler:The [[WordOfGod reason]] she dies in "Heroes" is because the producers needed to kill off a main character that the fans were heavily invested in.]]
* ''Series/StargateAtlantis'': Zelenka, Major Lorne and Colonel Caldwell were regularly-appearing characters and considered important enough to be referenced even in episodes in which they didn't appear, sometimes to create justification for why the characters aren't appearing when the plot indicates they really should be. None of them were ever billed as main characters.
* ''Series/StarTrekTheOriginalSeries'': Initially only Creator/WilliamShatner and Creator/LeonardNimoy were billed as main cast. Everyone else was viewed as a regular. From season 2, Creator/DeForestKelley was billed as main cast. The rest of "main characters" were billed in the closing credits as "co-stars".
* ''Series/StarTrekTheNextGeneration'':
** Dr. Pulaski was never added to the main cast list in season 2, despite being Dr. Crusher's replacement for the whole season. Creator/DianaMuldaur declined the offer to ensure her availability for other projects.
** Chief O'Brien starts off as a background character who eventually achieves a great deal of prominence and importance. Even though entire episodes centre around him, he never officially joined the main cast list. O'Brien's actor, Colm Meaney, left the show to join ''Series/StarTrekDeepSpaceNine'', where he received main cast billing.
** From seasons 2 to 6, [[Creator/WhoopiGoldberg Guinan]] appeared in 29 episodes, nearly a quarter of the remaining show, and was even featured in two official main cast photos.
* ''Series/StarTrekDeepSpaceNine'':
** Garak was intended as a single-episode character who eventually becomes incredibly important to the show's plot and MythArc. He is never billed as a member of the main cast, despite having that importance in the show. Creator/AndrewRobinson was given the opportunity, but declined the offer, and remains as a special guest star.
** Dukat is the major villain of the show, has personal involvement with several of the main characters, and becomes absolutely pivotal to the resolution of the MythArc. He never joins the main cast, remaining a special guest star.
** Rom and Nog are both introduced in the pilot and appear in several episodes each season, eventually joining the station crew. Neither of them join the main cast, continuing to be listed as guest stars.
** TheVoiceless Morn appears in over 90 episodes of the show. To put that into perspective, he appears in more episodes than Jake Sisko, who ''was'' in the main credits.
* ''Series/StarTrekPicard'':
** Only five actors appear in all three seasons of the show: Creator/PatrickStewart (as the titular Jean-Luc Picard), Creator/MichelleHurd (as his long-suffering NumberTwo Raffi Musiker), Creator/JeriRyan (reprising ''Series/StarTrekVoyager'' BreakoutCharacter Seven of Nine), Creator/BrentSpiner and Orla Brady. Only Stewart and Hurd are in the opening credits of all three seasons, with Ryan PromotedToOpeningTitles for the second season, and Spiner and Brady always credited as Guest Stars. (In defense of Spiner and Brady, they play multiple characters over the show's run.)
** The show's third season reunites the entire core cast of ''The Next Generation'', but -- aside from Stewart -- all of them are credited as Special Guest Stars. Despite this, two of them, Creator/JonathanFrakes and Creator/GatesMcFadden, appear in all ten episodes of the season, as does Creator/ToddStashwick as newcomer Captain Liam Shaw, whereas Hurd herself only appears in eight.
* Creator/JohnTravolta, who played Tony Manero in 1977's ''Film/SaturdayNightFever'', and Danny Zuko in in 1978's ''Film/{{Grease}}'', was given this status when he appeared part-time on ''Series/WelcomeBackKotter'' as Vinnie Barbarino during the show's fourth and final 1978-1979 season.
* Creator/ChrisNoth on ''Series/TheGoodWife'' is credited throughout the series as a special guest star for his role as Peter Florrick, the protagonist's husband. While he doesn't show up as often as the key stars, he is also alongside them in the show's DVD packaging and promotional materials.
** Creator/MichaelSheen, on ''The Good Wife'' spinoff ''Series/TheGoodFight'', is credited throughout his appearances in the show's third season as "Special Appearance by..." However, like Chris Noth on ''Wife'', he appears alongside the show's stars on the DVD packaging. Similar actors in future seasons--Creator/JohnLarroquette, Creator/MandyPatinkin, and Creator/JohnSlattery in seasons 4, 5, and 6 respectively, who all play characters meant to be central in their seasons--are actually credited as stars.
* Tim Conway appeared on every episode of ''Series/TheCarolBurnettShow'' for several seasons as a "guest star," before becoming an official regular.
* In ''Series/TheTudors'', there's Anthony Brophy. He played Eustace Chapuys, and is in more episodes than anyone except Creator/JonathanRhysMeyers and Creator/HenryCavill - who are the only actors who appear in every episode. Creator/JoelyRichardson (Katherine Parr) probably qualifies as well; she's in the main credits but billed as a "Special Guest Star", presumably because she's, well, ''Joely Richardson'', a member of the Redgrave acting dynasty.
* ''Series/{{Roseanne}}'' in its nine years never ''added'' actors to the main billing whose characters were newly introduced. The only character who was dropped from actor billing was Crystal after she never appeared anymore, but numerous other characters were introduced that became indispensable to the show's plot, particularly Bev, David, Jerry, Leon, Mark, Nancy and Scott. But none of their actors ever got more than a guest credit, as the main billing became strictly limited to the fictional immediate family (minus Jerry who was born later) and Jackie.
* Similar to ''Roseanne,'' ''Series/TheNanny'' never added actors to its main billing. Val, Yetta, and especially Sylvia became much more prominent as the series wore on, yet Creator/RachelChagall, Creator/AnnGuilbert, and Creator/ReneeTaylor were always guest stars.
* The U.S. version of ''Series/{{Shameless|US}}'' has Creator/JoanCusack playing Shelia, who continues to be credited as a guest star despite her major role in all 4 seasons. This has helped her secure Emmy nods for Outstanding Guest Actress every year.
* Matthew Timmons, who plays Woody on ''Series/TheSuiteLifeOnDeck'', never received anything other than guest star billing.
** Which is actually quite odd since when Doc Shaw showed up in the Second Season, he automatically got Star Billing even though they play comparable roles.
** The same is true for Adrian R'Mante who played Esteban in the parent series appearing in most episodes.
* ''Series/TwentyFour'' is a regular offender of this. Carlos Bernard (Tony Almeida) spent the whole ''first season'' as a guest star, despite getting ample screen time in nearly every episode. Mary Lynn Rajskub (Chloe O'Brien) spent ''two whole seasons'' as a guest star before finally being added to the main cast, again despite appearing in nearly every episode of both seasons. This is especially odd as Sarah Wynter (Kate Warner), James Badge Dale (Chase Edmunds), and Leslie Hope (Teri Bauer) all appeared in only one season each, yet received regular cast billing for their respective seasons.
** Roger Cross (Curtis Manning) spent the greater part of season four as a guest star before finally being bumped up to regular cast billing for the last third of it, and has remained at that position for the rest of his stay on the show.
** Oddly, Creator/LanaParrilla (Sarah Gavin) was also moved up to main cast mid-season in season 4 despite only appearing in half of the season and never appearing in any other season. On the other hand, Jude Ciccolella (Mike Novick) appeared in more episodes than all but seven other actors and never got billing above guest star--though he did get the "special appearance" billing reserved for returning cast members in the first episode of Season 5 along with Reiko Aylesworth (Michelle Dessler) and Dennis Haysbert (David Palmer), both of whom [[spoiler:were killed off in that episode]].
*** The opening credits of the season 5 premiere are somewhat of an indirect spoiler, as while Aylesworth is listed as a guest star, Carlos Bernard is listed with the main cast.
*** It's also a little ironic since Bernard was actually an AdvertisedExtra in season five.
** Reiko Aylesworth, D.B. Woodside (Wayne Palmer), and Louis Lombardi (Edgar Stiles) all notably appeared in all 24 episodes of a season (notably remaining vital to that year's events the entire time) before being upgradged to main cast the following one. In Woodside's case, he actually appeared in a little bit of the fifth season as well (he wasn't in the fourth) before finally joining the cast in season six. Similarly, like Carlos Bernard, Penny Johnson Jerald (Sherry Palmer) was in nearly every episode of the first season and didn't join the main cast until the second.
** Jude Ciccoella (Mike Novick) is also a notable case, as he was heavily involved in the first, second, fourth and especially fifth seasons, even going so far as getting a promotional photograph for the latter, but was never credited as a main cast member. Similar cases where an actor or actress was never officially part of the main cast but had a large enough role they might as well have been include Creator/ZacharyQuinto (Adam Kaufman) in season 3 and Necar Zadeganj and Nazneen Contractor (Dalia and Kayla Hassan, respectively) in season 8
* ''Series/BeverlyHills90210'': Kathleen Robertson (Clare) in season 5, plus Jason Wiles (Colin), Creator/EmmaCaulfield (Susan), and Creator/CameronBancroft (Joe) in season 6. Most appear in over ''25'' episodes of their respective seasons, though still credited under "guest star" billing (though Kathleen Robertson was PromotedToOpeningTitles come season 6). Also, when Luke Perry returned, he was credited as a "special guest star" though he appeared in every episode from his return until the end.
* Creator/BonitaFriedericy remained a "guest star" on ''Series/{{Chuck}}'' for three seasons, despite being in almost every episode. She was upgraded to the main cast for Season 4. In an earlier example, Season 1 had Creator/RyanMcPartlin and the actors for the Buy More staff, who appeared in most of the episodes (or in the case of both Creator/ScottKrinsky and Creator/VikSahay, ''every'' episode) but would have to wait until Season 2 before they were credited in the main cast.
* Creator/AmyAcker appeared in all but three episodes of the first season of ''Series/{{Dollhouse}}'', playing the important, highly recurring role of Dr. Claire Saunders. Despite occasionally appearing in more scenes than some of the regular cast, Acker was still considered a guest star. Creator/ReedDiamond, playing security chief Laurence Dominic, had similar treatment. This makes a little more sense in light of Season 2, where both of them are largely written out. Even better, Creator/JossWhedon received early warning that the show would be canceled and brought them back in for the finales, but who knows how much his ''original'' plan involved them.
* Kirsten Vangsness spent the entire first season of ''Series/CriminalMinds'' as a guest star before being promoted to the opening credits in Season 2. As of season 11, Vansgness appeared the most out of all the actors, even with original cast members Shemar Moore, Thomas Gibson, and Matthew Gray Gubler (though the former two have since left).
** Aisha Tyler appeared in all but four episodes of the eleventh season, though credited as a guest star, which eventually led her to be promoted to the opening credits in the twelfth season.
* In ''Series/FridayNightLights'', Buddy Garrity, played by Brad Leland, was a fixture of the show for all five seasons, appearing in all but three episodes (the most out of any character in the series outside of the central Taylor family) but Leland was never billed above guest star--even in season 5, where he appeared in every episode.
* In season 2 of ''Series/DawsonsCreek'', Meredith Monroe and Kerr Smith were both credited as Special Guest Stars. Kerr Smith was in every single episode of the season except the premiere and Meredith Monroe was in all but the finale. They were both upgraded to regulars for the third season.
** Busy Phillips stays a guest star throughout the entire 5th season, despite living with one main character and dating another while featuring in 22 out of 23 episodes. (The one she didn't appear in was a Joey-centric episode which none of the main cast but Creator/KatieHolmes appeared in). She actually featured ''less'' after her promotion to the main cast in season 6, missing 7 episodes of that season, including the finale.
* In ''Series/KathAndKim'' Magda Szubanski (who played Sharon Strzelecki) is credited in the opening as "Special Guest", even though she is a main character who appeared in every episode.
* On ''Series/HerculesTheLegendaryJourneys'', Michael Hurst was initially credited as a guest star. This was somewhat justified in the first season, as Iolaus only appeared in half the episodes and was established to have a home of his own. However, while he doesn't appear in every episode of Season 2, Iolaus still appears in the majority (even getting his first ADayInTheLimelight episode) and is by this time established as a traveling hero like Hercules. In Season 3, Michael Hurst was promoted to the opening credits with "Also Starring."
* Jesse L. Martin was listed as a guest star throughout all eight episode of ''The Philanthropist'', even though he had a larger role than Neve Campbell, who was given second billing.
* In the first season of ''Series/{{Glee}}'', Creator/NayaRivera (Santana) was in every episode, and Creator/HeatherMorris (Brittany) all of them but the pilot (both were made regulars in season 2) -- Harry Shum Jr. (Mike) has been in every episode so far but the first three, but was billed as a guest star until the third season.
** This trope was the case in Season 2 for Chord Overstreet (Sam), who appeared in all but one episode of the season. The producers' refusal to upgrade him to main cast member caused him to walk out between season 2 and 3. He returned in episode 8 of season 3, and finally got his main cast billing in season 4.
** True with all of the new cast members for season 4. Most of them have appeared in every episode (and played central parts too), but they are all billed as guest stars. As of season 5, they are full main characters...even after they are all dropped from the show halfway through the season.
* ''Series/PrisonBreak'' has had several - Stacy Keach (Warden Pope) appeared in 20 out of 22 episodes in season 1, Frank Grillo (Nick Savrinn) appeared in 18 out of 22, Muse Watson (Charles Westmoreland) appeared in 18 out of 22, Carlo Alban ([=McGrady=]) appeared in every episode in season 3, and Leon Russom (General Jonathan Krantz) appeared in every episode in season 4.
* In the first season of ''Series/BigTimeRush'', Tanya Chrisholm who plays Gustavo's assistant Kelly, wasn't put on the cast billings, despite being in every episode. The second season however added her to it.
* ''Series/ShakeItUp'' has Tinka Hessenheffer, who is played by Caroline Sunshine, who appears in every episode along with her twin brother Gunther, but is billed as a recurring character while Gunther is included as a regular in the opening credits. She was promoted to opening credits from the second season onwards.
* The long-running {{BritCom}} ''Series/LastOfTheSummerWine'' always listed (Dame) Thora Hird and Jean Alexander as being special guest appearances which at first they were as they appeared first in Christmas specials but later were in most or all episodes with Jean staying till the end, Dame Thora having died a few years previously.
* Even though the only episode of ''Series/JoanOfArcadia'' that "guest stars" Becky Wahlstrom and Christopher Marquette weren't in was the pilot, they weren't [[PromotionToOpeningTitles added to the opening credits]] until season two.
* ''Series/ParksAndRecreation'':
** Creator/ChrisPratt (Andy) got this for the first season. He got a PromotionToOpeningTitles (he was actually always there, just labeled as a "guest star") for season two. Interestingly, he was only supposed to be a temporary character, but that quickly changed before season two.
** Retta (Donna) and Jim O'Heir (Jerry) were also billed as guest stars despite appearing in most episodes. However they were PromotedToOpeningTitles halfway through season 6 after the departure of Creator/RashidaJones (Ann) and Creator/RobLowe (Chris).
* ''Series/MysteryScienceTheater3000'' is an unusual case, aside from all credits appearing at the end. In seasons 2 and 3, the [[MadScientist Mads]] and other visitors were billed under "special guest villains". In all other seasons (including season 1), they were billed under "also featuring", with the Satellite of Love portion of the cast billed under "featuring". Of special note: show creator Joel Hodgson didn't even get credit for playing Joel Robinson in the first season! (Fortunately, he still got credit for everything else he did, and the cast issue was rectified in season 2.)
* ''Series/HawaiiFiveO'', the original version of, is an unusual case - while Jack Lord receives starring credit and is the only person not to have the name of his character included in his billing, the other cast members aren't officially credited as co-stars; James [=MacArthur=] (second-billed in all but the final season, which he wasn't in) and all the other cast members listed in the opening credits are billed under "With."
* In ''Series/{{Eureka}}'', Chris Gauthier has notably appeared in most episodes of the series and maybe misses 2--3 per season at most, yet still has remained a guest star on the show.
** An even better example is Neil Grayston as Douglas Fargo. He's appeared in every episode of the series from the beginning and often plays an important part in the events of an episode (as opposed to Gauthier who often only appears in one scene an episode), yet somehow he didn't get credited as part of the main cast until the beginning of season 3.
* ''Series/TheWire'' is this trope all over the place.
** In five seasons, only 37 actors out of the over ninety characters that appeared regularly or semi-regularly were ever credited in the opening sequence. This includes actors like Creator/ClarkePeters, Creator/JimTrueFrost, Seth Gilliam, Domenick Lombardozzi, JD Williams, etc., who in all honesty were regulars in every way from the first season onward, but didn't get promoted to the opening titles until later (in some cases, MUCH later).
** Used still more with actors who were regulars but NEVER got promotion to the opening titles, such as Delaney Williams, Creator/HassanJohnson, Felicia Pearson, Julito [=McCullum=], Maestro Harrell and several others. In the case of the latter two, it was particularly strange since arguably both actors were portraying the central characters of season four.
** What makes it all the more odd is that the show would frequently introduce new regulars who were only around for one season (Creator/ChrisBauer, Creator/PaulBenVictor, Creator/AmyRyan, Creator/ClarkJohnson, Thomas [=McCarthy=], Michelle Paress) or promote background characters to "regular" status (Creator/GbengaAkinnagbe, Creator/NealHuff), or just promote people to the opening credits who'd been with the series for a while, regardless of whether their role increased at all (Michael Kostroff, Isiah Whitlock, Jr.) without even thinking of promoting the above actors who unquestionably deserved it.
** Of course, the argument could be made that if everyone on that show who appeared regularly received billing in the opening sequence, the sequence would take up half the episode. However, it does seem odd and random who was and who wasn't credited as a regular.
* ''Series/TheXFiles'' does this frequently. Mostly because the show had the same opening titles through seasons 1--7, which only billed Creator/DavidDuchovny and Creator/GillianAnderson as characters in the show. Everyone else, even highly recurring characters, were guest stars. This continued through season 8, when the credits were changed to reflect David Duchovny's absence from the show, but still only had Gillian Anderson and Creator/RobertPatrick in it. Even Creator/MitchPileggi, who played Walter Skinner and appeared in 81 episodes, did not get a main title credit until the show's final season, season 9.
* This fate befell Janel Moloney in the first season of ''Series/TheWestWing'', whose character Donna Moss would become one of the most prominent and popular characters amongst the show's EnsembleCast (she appears in every episode during season 1, in fact); the situation was remedied by Season 2, with Maloney given a slot in the main titles.
* Allison Scagliotti as Claudia Donovan in the first season of ''Series/Warehouse13''. Since her introduction in episode four, she received more screen time than [[AdvertisedExtra Daniel Dickinson (Simon Reynolds)]], appearing in every episode since. She was PromotedToOpeningTitles for season two.
** Aaron Ashmore as Steve Jinks is introduced as Myka's replacement in the first episode of season 3, and appears in a major role in almost every episode of the season, but remains in the guest cast. [[spoiler: He's killed in the season 3 finale, but revived in the second episode of season 4, and eventually promoted to the 'Starring' cast midway through that season, although he still doesn't appear in the title sequence with the main four characters.]]
* Karri Turner never received star billing on ''Series/{{JAG}}'' despite regulary appearing on the show for 9 seasons.
* Creator/MeghanOry as Ruby/Red Riding Hood on ''Series/OnceUponATime'' appeared in eight more episodes than regular cast member Raphael Sbarge in season one. She was PromotedToOpeningTitles for season two, where she only appeared in 11 of the 22 episodes, becoming an AdvertisedExtra, the exact inverse of this trope.
* ''Series/GreysAnatomy'' has problems with this. Throughout the show's run there have been a number of characters billed as guest stars but treated by the writing staff as MainCharacters, culminating in the current season (9) in which ''five'' NewMeat interns are sharing, and in some cases stealing, the spotlight from the 11-member EnsembleCast. ...Of course, combining that number with [[MoneyDearBoy the budget]] might explain this trope.
* Jim Beaver for his role as Bobby Singer on ''Series/{{Supernatural}}''. After becoming more prominent in the second season he started appearing very frequently as the TeamDad and become arguably the most important character after Sam and Dean, yet he was always billed as a guest star, even when you take into consideration that the few other actors aside from the main two to also be billed as series regulars (Katie Cassidy and Lauren Cohan in season 3 and Creator/MishaCollins in seasons 5 & 6) actually appeared in ''less'' episodes in their seasons than he did (with the exception of Collins in the fifth season). [[spoiler: Though with Bobby being killed off in season 7 and thus limiting his appearances, his role as a guest star is a bit more justified now.]]
** There was actually a bit of a push from the fans of the show to make him a regular cast member around the same time Misha Collins became one. Beaver actually spoke out against this, saying he was flattered by their concern, but it just wasn't necessary, as his status as a guest star left him free to float in and out and work on other projects if he wanted to, and becoming a regular cast member wouldn't allow him that.
** There was also the concern of Beaver being a single father and raising a special needs daughter. The guest star status also allowed him more freedom to return home.
* Richard Karn didn't get promoted to the main cast on ''Series/HomeImprovement'' until season 2, despite appearing in every season 1 episode (and being credited at the end). This may be partly due to the fact that Al, his character, was meant to be a temporary replacement for the intended Tool Time assistant during the original actor's unavailability, and managed to stick around instead. (Interestingly, Earl Hindman's credit is the only one in the season 1 opener not to portray the actor, perhaps in keeping with Wilson's "invisible" status. He showed up starting in season 2.)
* Jenilee Harrison was this during season 5 of ''Series/ThreesCompany''. Due to her salary dispute, Suzanne Somers had her appearances reduced to only the tag scene of each episode, and Jenilee's character Cindy moved into the apartment as the replacement roommate. Instead of making a new credit sequence mid-season, they simply kept the one that listed Suzanne as a star and credited Jenilee at the end of each episode as a guest, even though, for all intents and purposes, it was the other way around.
* On ''Series/AmericanHorrorStoryCoven'', Gabourey Sidibe, Jamie Brewer, and Creator/AngelaBassett are credited as "special guest stars" despite appearing in most episodes and getting at least as much screen time as many of the credited leads.
* Kai Owen was credited as a guest star for his appearances as Rhys in Series 1 and 2 of ''Series/{{Torchwood}}'', despite the fact that he appeared in twenty episodes out of twenty-six, [[note]]9 out of 13 in Series 1; 11 out of 13 in Series 2[[/note]] and was basically TheSixthRanger after discovering the truth about Torchwood in Episode 2x04. Contrast with Creator/FreemaAgyeman as [[Series/DoctorWho Martha]] (3 episodes), Indira Varma as Suzie (2 episodes) and Bryan Dick as Adam (1 episode), who were all credited as main cast during their appearances! [[note]]{{Justified}} with Suzie and Adam as their fake promotion to main cast was a plot point in their respective episodes, though no similar excuse exists for Martha.[[/note]] Series 3 and 4 rectify this by promoting him to the main cast, however.
** Tom Price as Andy Davidson has also appeared in fourteen TV episodes, a couple of the radio episodes, and has narrated a number of the audio books (a job usually reserved for the series' lead actors). In Series 3 and 4 in particular he appears in more than half of the episodes, and has more appearances to his name than the new leads introduced in those series, but is still billed below them as a guest star.
* Series/{{Arrowverse}}:
** Creator/CaityLotz has appeared as Sara Lance / The Canary in every episode of the second season of ''Series/{{Arrow}}'' save one, which is still more than most of the show's other second season series regulars (only four of the nine credited leads have appeared in as many or more episodes than she has), and plays a very prominent role in the season, yet is credited as a guest star throughout. However, she's then killed off in the third season premiere. If anything, this act may have helped with the surprise of her death - if Lotz had been credited as a regular in the second season and then a guest star just in the third, it would have been pretty apparent to the viewers that she wasn't going to survive the episode.
** Interestingly played with regarding Creator/KatieCassidy. She is part of the original cast members of ''Arrow'' and gets the regular credit. However, her character is killed off in Season 4, but Cassidy continues to be a part of the Arrowverse, albeit playing a doppelganger of her character, who guest stars in ''Series/{{The Flash|2014}}''. When said doppelganger appears in ''Arrow'' Season 5, Cassidy is credited with "special guest star" since she only appears in three of the season's 23 episodes. The next season, she is promoted to series regular again, but instead of simply updating her to regular credit, she gets "with", a form of AndStarring previously used by Creator/SusannaThompson, Creator/JohnBarrowman and Creator/JoshSegarra, probably to make up for no longer being the female lead. The singling out carries on until the end of the series; the final season updates her to "special appearance by", the same as Matt Ryan below.
** On the third season of ''Series/TheFlash2014'', Creator/TomFelton gets the "Special Appearance By" credit, despite appearing in well over half the episodes and being a recognised member of Team Flash.
** Creator/MattRyan retains his "special appearance by" credit for every episode of ''Series/LegendsOfTomorrow'', even after joining the main cast in Season 4.
** Gary Green has been a constant face in ''Legends of Tomorrow'' since Season 3. Despite this, Creator/AdamTsekhman is always credited as a guest star. This continues to Season 5, where Tsekhman is still a main character but continues to be credited as guest, yet Creator/OliviaSwann (Astra Logue), who debuts in the final two episodes of Season 4, is immediately promoted to series regular when Season 5 is confirmed.
* Hitchcock and Scully of ''Series/BrooklynNineNine'' are credited as recurring co-stars, despite appearing in every episode and having lines in nearly every ensemble scene alongside the main cast. They finally get added to the full titles beginning in Season 6.
* Creator/MackenzieLintz as Norrie on ''Series/UnderTheDome'' appeared in every episode of the first season and was fairly important to the plot throughout [[spoiler:as one of the Four Hands]], but didn't get credited as a regular until season 2.
* ''Series/VeronicaMars'' always had an interesting relationship with leads v. guest stars. The actor portraying Ms Dent was listed as main cast in Season 1, despite only appearing for a handful of scenes over four episodes (and disappearing from the credits, though not promotional materials, after seven). In Seasons 2 and 3, new one-season-arc characters Jackie, Piz and Parker were promoted to leads above some recurring co-stars who played equally significant roles in all three seasons. Season 1 recurring characters Dick and Cassidy were promoted to lead cast in Season 2, [[spoiler:though it's rumoured that Dick was only promoted to disguise the fact that Cassidy's promotion was due to him being the BigBad of the season, as his role didn't really expand until Season 3]]. Meanwhile in all this, Tina Majorino as "Mac" appeared in at least as many or more episodes than Dick, Cassidy and Jackie, played a more significant role in the main plot than two of the three, yet wasn't promoted to lead credits until Season 3, along with Michael Muhney as Don Lamb, another actor who'd been with the show since the first season.
* ''Series/{{Oz}}'': Most seasons are only 8 episodes long (except for season 4 which had 16) so many characters appear in every episode. Perhaps the most egregious example of this is George Morforgen as Bob who appeared in every single episode of the series but never received starring billing.
** ''Oz'' had three levels of billing for its opening credits during the first two seasons: Starring, Also Starring and Guest Starring. Creator/ErnieHudson, Terry Kinney, Creator/HaroldPerrineau and Eamonn Walker were the only ones billed as "Starring" for the first season, while Kirk Acevedo, Creator/EdieFalco, Creator/RitaMoreno, Tony Musante, Leon, Creator/JKSimmons, Lee Tergeson, Sean Whitesell, Creator/DeanWinters and Creator/BDWong were "Also Starring". In the second season, Acevedo, Moreno, Simmons and Tergeson were moved up to "Starring" while Creator/AdewaleAkinnouyeAgbage, Željko Ivanek, George Morfogen and Lauren Velez were moved up to "Also Starring". With the exception of Ivanek, every new addition to the "Also Starring" list had appeared prominently in every episode of the first season. The "Guest Starring" billing disappeared from the opening credits of seasons three to six, which meant that many actors were credited as "Also Starring" despite only appearing in one or two episodes. Numerous "Also Starring" and "Guest Starring" actors played major characters on the series, despite never being moved up to "Starring" or, in some cases, ever being credited as regulars. Philip Scozzarella, Otto Sanchez, [=Carl DiMaggio=], Timothy L. Brown, Steven Wishnoff, Blake Robbins and many others too numerous to mention never had their names in the opening credits at all, despite appearing as major characters for entire seasons, or longer, and others like Granville Adams, Robert Clohessy, Seth Gilliam, Tom Mardirosian, Craig "muMs" Grant, Kristen Rohde, JD Williams Scott William Winters were listed as "Guest Starring" for the first two seasons, and only became "regulars" by virtue of the "Guest Starring" billing being removed. All of them played major characters.
* ''Series/OrangeIsTheNewBlack'' credits Laverne Cox as a guest star, even though she's in practically every episode, and it takes place in prison so her character is not going anywhere any time soon. It's especially jarring since it made Cox into a bigger celebrity than any of the actual main stars. Season 3 added Ruby Rose as Stella, who also wasn't credited as a lead actress but quickly soared to superstardom immediately upon the season's launch.
* ''Series/NedsDeclassifiedSchoolSurvivalGuide'' always had its official main cast limited to the three lead actors: Devon Werkheiser, Creator/LindseyShaw, and Daniel Curtis Lee, plus Creator/DaranNorris as Gordy (and Jim J. Bullock as the original mentor character who instead remained a side character). As such, key players like Christian Serratos, Kyle Swann, Carlie Casey, Don Creech, and Hamilton Mitchell were never given anything other than guest credits.
* ''Series/AgentsOfSHIELD'':
** The show started out with a fairly straightforward six character ensemble, all of whom were given lead credits, and with all other characters one-shots or recurring guests with one or two appearances over the course of Season 1. Then we were introduced to Antoine "Trip" Triplett (B.J. Britt) who joined the team in the latter half of the first season and was a Fake Guest Star for the remainder of that season and the first half of the second.
** Bobbie Morse (Adrienne Palicki) was introduced early in Season 2, and was [[PromotionToOpeningTitles promoted to regular]] after the Christmas haitus. Not so lucky was Alphonse "Mac" Mackenzie (Henry Simmons) who appeared in literally every episode of the second season, credited as a guest star for all of them. This might have been a way to [[spoiler: fool viewers into thinking his supposed betrayal then supposed departure would be permanent. He was promoted to regular for the third season]].
** On the antagonists' side, Creator/RuthNegga (Raina) first appeared in 1x05 and appeared five more times over the of Season 1; in Season 2, she's in about half the episodes (as is lead-credited [[spoiler:antagonist]] Creator/BrettDalton), but is still credited as a guest star, despite having more appearances to her name than any BigBad she's acted as TheDragon for, and despite appearing at several publicity events with the original six leads between seasons.
** Creator/NataliaCordovaBuckley is a semi-regular character in Seasons 3 and 4, but only became a regular in Season 5.
** In Season 4 Mallory Jansen (AIDA/Agnes/Ophelia/Madame Hydra) portrays the BigBad of the entire Season, featuring heavily in all three big story arcs while only missing two episodes, and appearing in more episodes than John Hannah (Radcliffe), who is a main cast member.
** Deke Shaw appears in most of the fifth season's episodes, but his actor, Jeff Ward, is credited only as a guest star. This was likely done to hide the fact that [[spoiler:Deke gets sent back to the present]], and he is PromotedToOpeningTitles for the final two seasons.
** Joel Stoffer (Enoch) appears in most of the sixth and seventh seasons, but is only billed as a guest.
** [[spoiler:Daniel Sousa (played by Creator/EnverGjokaj)]] appears in ten of the seventh season's thirteen episodes, but is billed in the AndStarring section, separate from the main cast. This was likely done because the character in question is introduced a few episodes into the season, and [[spoiler:the fact that Team Coulson TrickedOutTime to bring him along is a massive spoiler]].
* Sinjin Van Cleef from ;;Series/{{Victorious}}'' appeared in almost every episode, but the actor portraying him (Michael Eric Reid) was never credited with the main cast.
** In fact, Sikowitz, their main teacher ([[TokenAdult and the only adult to play a significant role in the show]]), appears in most episodes too, but Eric Lange was never credited in the opening credits.
* On ''{{Series/Alias}}'', Creator/GregGrunberg appeared as Agent Eric Weiss in virtually every episode of season 1 (where he was uncredited) and season 2 (where he was billed as a guest star), before being promoted to the opening credits in season 3.
* Farkle (Corey Fogelmanis) in ''Series/GirlMeetsWorld''. In season 1, he is sometimes credited as a guest star, and sometimes as "[[AndStarring also starring]]". He's [[PromotionToOpeningTitles added to the opening sequence]] in season 2.
* ''Series/LabRats'':
** Maile Flanagan (Principal Perry) was never credited as anything more than a guest star, despite playing a role comparable to that of Hal Sparks' Donald Davenport.
** A similar case can be made with Creator/AngelParker (Tasha), although to a lesser extent.
** Jeremy Kent Jackson, who played Douglas Davenport, is a similar case; while originally only a recurring villain, following his HeelFaceTurn he appeared regularly, and in Season 4 he tends to appear just as often, if not more so, than his brother.
* Carlos Lacamara, who played Horace on ''Series/MightyMed'' was never anything more than a guest star, even though he appears in more episodes than Augie Isaac (Gus), who ''was'' in the main cast.
* ''Series/AgentCarter'':
** In the first season, Angie appears in all but two episodes, yet LyndsyFonseca is billed as a guest star.
** The second season goes even farther, with the official main cast being limited to returning people. The new ones are all considered "Recurring" at best, even though a few of them ([[spoiler:Wynn Everett as Whitney Frost and Reggie Austin as Jason Wilkes]]) appear in every single episode, making them more prominent than "Main" Creator/ChadMichaelMurray (Jack Thompson).
* [[Franchise/TheMuppets Muppeteer]] Julianne Bueschner has performed at least one character in every episode of ''Series/{{The Muppets|2015}}'' as of December 2015, yet she keeps getting a "guest star" credit. Though to be fair, her two prominent characters (Denise and Yolanda) aren't as major as, say, Kermit.
** Speaking of Kermit, he kinda got forced into this status on ''Series/SesameStreet''. He was a regular in the first season, but was dropped for season 2 after people became concerned over his appearances in non-''Sesame'' projects that weren't educational. From season 3 onwards, he came back in a reduced form -- [[CommutingOnABus he'd appear every so often]], mostly in skits (either with Grover or Cookie Monster, or else the long-running ''News Flash'') and the occasional Street scenes. This remained the pattern into the late 1990s. Then Creator/{{Disney}} bought the non-''Sesame'' Muppets in 2004 (Sesame Workshop had bought the rights to their Muppets from The Jim Henson Company two years prior), so his appearances since then have been reduced to minor cameos for [[MilestoneCelebration anniversary episodes]].
* ''Series/BreakingBad'': While Creator/BobOdenkirk (Saul Goodman) and Creator/GiancarloEsposito (Gus Fring) became members of the main cast in season 3 (with Saul appearing in 10 of 13 episodes, and Gus in 11 of 13), they were still billed like they were guest stars, meaning they weren't billed in episodes where they didn't appear. In season 4, they were promoted to the main cast (meaning they'd be billed for all 13 episodes of the season, even episodes where they were absent).
* Creator/GregProops (Max Madigan) and Ron Butler (Oscar) appeared in every episode of the first season of ''Series/TrueJacksonVP'', though billed as guest stars. This may have been accidental, given that they appeared in the opening sequence. They would be promoted to opening credits in the second season, along with Creator/RobbieAmell (Max's nephew Jimmy, who was a recurring character in the first season).
* ''Series/MightyMorphinPowerRangers'' and its sequels, whenever a former Ranger or series regular appeared, they were listed as Guest Star, due to the heavy issue of RevolvingDoorCasting that meant, in at least three major cases in the original series alone, you could spot any new or future ranger by simply looking at the Guest Starring credits.
** Sam (voiced by Brett Stewart) from ''Series/PowerRangersSPD'', Robo Knight (voiced by Chris Auer) from ''Series/PowerRangersMegaforce'', and Steel (voiced by Jamie Linehan) from ''Series/PowerRangersBeastMorphers'' are the only Sixth Rangers who are never [[PromotionToOpeningTitles added to the opening credits]], all of them only being listed in the ending credits because they are played by voice actors. What's weird though is that Commander Cruger, also from S.P.D., is given a spot in the opening credits, however this is due to the fact that his voice actor John Tui is also his suit actor as he is one of the few to serve as both suit actor and voice actor for the same character, with another one being Danny Wayne Stallcup, who served as Jindrax's suit actor in ''Series/PowerRangersWildForce'' and would take over as his character's voice actor from the fifth episode onwards, replacing Richard Cansino.
** While full-suited characters usually aren't credited in the opening sequence (with a few exceptions like the aforementioned Cruger), in some seasons even very major human characters often won't get credits if they're not full-time rangers. For example, [[MissionControl Commander Shaw]], Mayor Daniels, [[EvilCounterpart Blaze, and Roxy]] of ''Series/PowerRangersBeastMorphers'' are never given credits despite being major players in the plot, and Nate is only PromotedToOpeningTitles after he becomes the SixthRanger.
* ''Series/KirbyBuckets''' lead cast never expanded beyond the five main cast members (Jacob Bertrand, [=MeKai=] Curtis, Cade Sutton, Olivia Stuck, and Tiffany Espensen), even though some actors, notably Michael Naughton, Suzi Barrett, Jack Foley, and Stephen Kearin, were by Season 3 appearing more often than the frequently-absent Espensen. Also, since they're just voices, none of Kirby's animated characters' voice actors are in the opening credits.
* ''Series/HenryDanger'': Michael D. Cohen (Schwoz) has appeared in almost every episode of the show ever since he was introduced. It wasn't until season 5 where he finally got upgraded to the opening credits.
* ''Series/TheThundermans'': Dana Snyder, the voice of Dr. Colosso (and his live-action actor whenever he turns human), appears in all but a few episodes, but doesn't make it past guest-star status because first, he is only a voice, and second, his near-perfect attendance record still isn't a match for the other Thundermans' 100% attendance.
* ''Series/IronFist2017'': With her screen time and importance to the plot exceeding that of some of the leads, Wai Ching Ho (Madame Gao) fits the bill. This would continue into ''Series/TheDefenders2017''.
* Speaking of ''Series/TheDefenders2017'', Jessica Henwick is a perfect example. The show is a crossover between the four main Marvel Netflix shows: ''Series/Daredevil2015'', ''Series/JessicaJones2015'', ''Series/LukeCage2016'', and ''Series/IronFist2017'', and as such, only their actors and the main villains received top billing. Colleen Wing is a former member of The Hand, and is actually far more relevant to the main plot than Luke or Jessica, whose involvement in the miniseries felt ''extremely'' forced at times. But as Danny Rand's girlfriend, she's relegated to supporting status along with all the other love interests and best friends. This is actually consistent with some criticisms of ''Iron Fist'', as many people felt ''she'' should have been the main character due to having the more compelling story arc.
* In ''Series/SEALTeam'', Lt. Commander Eric Blackburn appears in every single episode of Season 1, but his actor Judd Lormand is only credited as a guest star. (He was promoted to series regular for Season 2.)
* ''Series/TheFortyFourHundred'': Richard Kahan (Marco) appears in 32 of the series' 44 episodes, more than any other guest star. He is the only actor to appear in all four seasons without ever being part of the regular cast.
* In ''Series/ElChavoDelOcho'' and ''Series/ElChapulinColorado'', the actors that take part of each episode are listed in the introduction. If a character from another ''Series/{{Chespirito}}'' skit appears (e.g. El Chavo and Quico in a Chapulín Colorado episode), they are listed as a guest star, even if the actor that plays them was already billed.
* Odd case involving Jenna von Oy on ''Series/{{Blossom}}''. von Oy had been cast as [[YouAreNumberSix Six]] [=LeMure=] in the series' pilot and was originally in the opening credits, only to also be cast on the short-lived Creator/{{CBS}} sitcom ''Lenny'' (starring [[TheEponymousShow comedian Lenny Clarke]]); which like ''Blossom'' was also created by Don Reo and shared most of the same production personnel (from Wit[=/=]Thomas Productions), resulting in von Oy being moved to "Special Guest Star" billing when ''Blossom'' premiered in [[MidseasonReplacement January 1991]]. Eventually, ''Lenny'' was canceled in March 1991; and by the start of the 1991-92 season (incidentally, the first full season for ''Blossom'') von Oy had been moved back to the opening credits.
* ''Series/GameShakers'': Bubba Ganter and Shel Bailey as Double G’s assistants Bunny and Ruthless. They appeared in almost every episode of the show, but the show got cancelled before they could move up.
* ''Series/OneHundredThingsToDoBeforeHighSchool'': Brady Reiter appeared in almost every episode of the show, but she never got promoted to the main cast. Then again, the show ended too early for her to do so.
* ''Series/ResidentAlien'':
** Meredith Garretson appears as Kate Hawthorne in every episode of the first season of ''Series/ResidentAlien'' and has a fairly significant role, but is nevertheless credited as a guest star. This continues to be the case in the second season.
** This is also the case for Elizabeth Bowen as Deputy Liv Baker. However, unlike Garretson, Bowen is credited as starring cast in the second season.
* ''Series/{{iCarly}}'': Although Gibby's actor Creator/NoahMunck was added to the intro credits when he became a regular character, the same was not true for T-Bo's actor [=BooG!e=]. While initially a recurring character, T-Bo was in nearly every episode of the last few seasons, had several plots focused on him, and even appeared with the main cast in the closing scene of the final season's intro. Yet [=BooG!e=] was always credited as a guest.
* Claire Holt was in 18 episodes in both Season 3 and 4 of The Vampire Diaries but was never added to the main cast. [[note]]No female actor was promoted throughout the series' eight seasons]]. Ironically when she became a regular on the spinoff, The Originals, she is featured far less.[[/note]]
* Kennedy Cates is prominent in every episode of ''[[Series/SweetVicious Sweet/Vicious]]'', and her actress, Creator/AishaDee, had already been a series regular in other series. However, she'd already been contracted to star as one of the co-leads of ''Series/TheBoldType'', debuting that same year, meaning she wouldn't have been able to also be a series regular here.

[[folder:Radio]]
* ''Radio/TheBrewingNetwork'''s John Plise on Brewing With Style. In one episode Jamil wonders aloud how long he will be introduced as a special guest.
[[/folder]]

[[folder:Web Original]]
* In-universe example: Internet movie review series ''WebVideo/OnCinema'' introduces Gregg Turkington (aka Creator/NeilHamburger) as a guest reviewer in every episode, in spite of the fact that he appears in every episode except one. One of the underlying conflicts in the series is Gregg's desire to be promoted to co-reviewer and [[Creator/TimAndEric Tim Heidecker]]'s refusal to grant this or share the show.
* For some reason, LetsPlay/{{Sips}} refers to LetsPlay/LewisBrindley as a "special guest" in the description for his ''VideoGame/GarrysMod'' series, even though Lewis has been in almost every session of ''VideoGame/TroubleInTerroristTown'' for at least two sessions (read: multiple rounds throughout many videos, ending at one point and then starting anew). The most likely explanation is that he started as a guest but then kept playing, and Sips just forgot to change the text. This has been a ZigZaggedTrope since, with some descriptions mentioning him and others still referring to him as a "special guest".
* [[Podcast/GiantBomb The Giant Beastcast]] frequently mentions Jeff Bakalar being in the "rotating chair", but he's rarely not in an episode. This does not go without lampshading. Bakalar also has to frequently remind people that he doesn't actually work for Website/GiantBomb.
* Played for laughs with Rich Evans on ''WebVideo/HalfInTheBag''. Despite playing Mr. Plinkett from the start of the series and featuring prominently in other ''WebVideo/RedLetterMedia'' projects, Mike and Jay often introduce him as a friend of theirs who people are probably unfamiliar with.
[[/folder]]

[[folder:Western Animation]]
* More a Character example; in ''WesternAnimation/OneHundredAndOneDalmatianStreet'', the Dimitri Trio do feature in the official promotional materials, and have played prominent roles in a number of episodes, yet the three are not considered part of the main group of pups, nor do they appear in the opening title sequence.
* In ''WesternAnimation/{{Archer}}'', Ray Gillette never appears in the main credits despite having appeared regularly for every season. This probably is because he's voiced by the series creator, Adam Reed.
* ''WesternAnimation/AllGrownUp'' has Harold Frumpkin, the SixthRanger of the main group. He appears in nearly every episode, but is never listed in the show's opening theme with the other children.
* ''WesternAnimation/{{Futurama}}'' voice actors Creator/LaurenTom (Amy), Creator/PhilLaMarr (Hermes) and David Herman (various characters, most notably Scruffy) were always "guest stars" during the original run, despite the fact that at least one of them appeared in every episode (although, in Season 4, they did get their own caption instead of having to share one). In the Creator/ComedyCentral run, Tom, [=LaMarr=], and Herman gained starring credits.
** This appears to be a pattern for Lauren Tom, who also got guest billing for voicing Connie and Minh on ''WesternAnimation/KingOfTheHill''.
* The voice actors for the recurring villains on ''WesternAnimation/KimPossible'' are always listed as guest stars, even though two of them (Sullivan and Creator/JohnDiMaggio) are in ''half'' the episodes (sometimes as characters other than their primary villains).
* ''WesternAnimation/TheSimpsons'':
** Whenever Edna Krabappel appeared, Marcia Wallace was billed as a guest star. Edna was the ''only'' character the late Marcia Wallace voiced (she could have been included in the regular cast like Creator/YeardleySmith, who also only voices one character, but decided against it). She also received guest star credit whenever Edna appeared, ''even if she doesn't say anything''. She's billed in appearing in ''176 episodes.''
** Creator/PhilHartman had a similar thing going on, being credited in 55 episodes at the time of his death in the tenth season (which meant he appeared in about one of every four). Unlike Wallace, Hartman's credits were spread out among a large number of characters, between his "regulars" (Lionel Hutz and Troy [=McClure=]), various one-offs (Evan Conover, Lyle Lanley, 'Smooth' Jimmy Apollo) and even roles that were eventually recast after his passing (Nelson's dad, Bill Clinton). The same applies with both of his successors Karl Wiedergott and Chris Edgerly, though with them voicing one-offs and background roles near consistantly with few to no regular roles.
** Maggie Roswell, somewhat infamously, was basically treated as a guest star despite voicing Helen Lovejoy, Maude Flanders, Luann Van Houten, and Ms. Hoover, all of whom appeared fairly regularly, and even got nominated for an Emmy and an Annie while working on the show. Fox only paid her $1500 an episode, despite the fact that she had to fly from Colorado to California to record episodes, and had her pay her travel costs on her own dime--the resulting dispute led to Maude being killed off and most of Roswell's characters being retired for several seasons. Even with that gap in mind, she's still been in 243 episodes as of this writing, more than both of the above combined.
** Pamela Hayden and Russi Taylor voice (or voiced) pretty much all the kids who aren't Lisa or voiced by Nancy Cartwright, while Tress [=MacNeille=] voices most of the older women who aren't voiced by Marcia Wallace or Maggie Roswell. Russi Taylor at the time of her death had appeared in 195 episodes, while Hayden and [=MacNeille=] both have around triple that as of this writing. Over six hundred episodes, and still an "Also Starring..."
* In the ''WesternAnimation/BatmanTheAnimatedSeries'' follow up series ''The New Batman Adventures'', Creator/MarkHamill is credited as a guest star, despite appearing as ComicBook/TheJoker in more episodes than supposed regular Creator/LorenLester.
