Whenever a series continuation is released on Netflix, the site has a policy to recruit as many of the original actors as possible. This is especially true with the foreign dubs, with a couple examples:
Excellently, the Italian dub of Gilmore Girls: A Year in the Life stayed at the same studio (PUMAISdue), with the main characters' voice actresses (Myriam Catania and Giuppy Izzo) appointing themselves as the dubbing directors and inviting all the original actors back after nine years, including Claudia Pittelli, the original voice actress of Paris in the first five seasons, who had left the role in 2005 due to her pregnancy.
The Addams Family had a 1977 Reunion Show called Halloween with the New Addams Family, which had most of the actors from the original show reprise their roles (they even have Ken Weatherwax and Lisa Loring play adult versions of Pugsley and Wednesday). The only actors who weren't able to reprise their roles were Blossom Rock and Margaret Hamilton, who played Gomez's mother Grandmama Addams and Morticia's mother Hester Frump respectively.
The Flash (2014) has Mark Hamill reprising his role as the Trickster from the 1990 live-action show and Justice League Unlimited, while Amanda Pays reprises her role as Tina McGee. Vito D'Ambrosio also returns as Bellows, though this time, the character is the mayor, not a cop ("Elongated Journey into Night" later establishes that he used to be a cop). Additionally, the Season 3 premiere, "Flashpoint", sees Alex Désert reprise the role of Julio Mendez.
The Italian dub has Giorgio Lopez reprising the role of Trickster (again from the dub of the 1990 show).
Mark Hamill also plays the Trickster of Earth-3, who is clearly an Expy of the Joker. Hamill is well-known for voicing the Joker in animated series.
Corinne Bohrer reprises her role as Zoey Clark (AKA Prank), the Trickster's partner-in-crime. In this version, she was also his lover and even gave him a son. The photo of the Trickster and Prank during their crime spree 20 years before is a still from the 90's show.
An interesting case with John Wesley Shipp, who played Barry Allen in the 1990s show. In the 2014 show, he plays Henry Allen, Barry's dad. He later also plays Jay Garrick, the Flash of Earth-3, making it the second time Shipp has played a Flash (albeit a different one). A clip from the '90s show is also shown at one point, implying that the universe of the '90s show exists in the 2014 show's multiverse. Later it's revealed that this show takes place in Earth-90, and he once again plays the role of the '90s Barry Allen for the Elseworlds (2018) crossover.
Speaking of Smallville characters, Erica Durance also appears as Lois Lane alongside Elizabeth Tulloch as the franchise's normal Lois. Michael Rosenbaum was approached for an appearance as Lex Luthor, but unfortunately declined.
Burt Ward reprises his iconic role from Batman (1966) as an elderly (and seemingly retired) Dick Grayson. He even gets a callback to his old catchphrase where he shouts "Holy crimson skies of death!" after seeing the antimatter wave heading for his world.
Ash vs. Evil Dead brings back Bruce Campbell as his iconic character Ash Williams. Ellen Sandweiss, who played Ash's sister Cheryl in the original film, reprises her role in the show's second season.
Babylon 5: Julie Caitlin Brown played recurring character Na'Toth in the first season, but was unable to return for the second, resulting (after an attempt to recast the part proved unsatisfactory) in the character being written out with a line of dialogue explaining that she had gone missing in the war and was presumed dead. In the final season, Julie Caitlin Brown returned to the role for one episode to give the character a proper exit.
In the Japanese dub of the TV documental about the actress Audrey Hepburn, Audrey: More Than An Icon, the titular actress is dubbed by Masako Ikeda, who dubbed her in many of her films in the past.
Variant: Josh Groban sang "Evermore" on the soundtrack for Beauty and the Beast (2017). When the special Beauty and the Beast: A 30th Celebration came out, Groban downright played the Beast, and a scene of him singing "Evermore" was added even if it wasn't on the cartoon to highlight why Groban was there.
Buffy the Vampire Slayer pulled off a rather impressive string of actors reprising their characters in a single scene in the 7th season opener, with all previous Big Bads being impersonated by the new enemy who can take on the appearance of anyone dead or once dead. While one of them, Spike, had become a regular character on the series all of the others were reprised by the same actors.
Similar to the Buffy example, the climactic scene of the series finale of Desperate Housewives featured the spirits of almost every character who had died on Wisteria Lane, played by the original actors. The first to be seen was Mike Delfino (James Denton), who'd died in the final season, and the last was Mary Alice Walker (Brenda Strong), who'd committed suicide at the start of the first episode.
After 34 years, William Zabka and Ralph Macchio take on the roles that made them stars (Johnny Lawrence and Daniel LaRusso, respectively). Also returning is Randee Heller as Daniel LaRusso's mother and Martin Kove as John Kreese.
Season 3 sees the return of Kumiko and Chozen Toguchi, once again portrayed by Tamlyn Tomita and Yuji Okumoto. Even Traci Toguchi, the girl saved during the second film's hurricane, returns for a brief scene. Also Elisabeth Shue as Ali Mills.
The Degrassi franchise has had many instances of this.
Stefan Brogen, Pat Mastroianni, Stacie Mistysyn, Amanda Stepto and Dan Woods all were at some point or another series regulars on Degrassi: The Next Generation reprising their roles from Degrassi Junior High, well over a decade after the original show had ended. Other Degrassi Junior High cast members made sporadic guest appearances throughout Next Generation's run. The most prominent example of this was the show's first episode which involved a class reunion where eleven actors, in addition to the aforementioned five, came back to play their characters one last time. Other appearances, with several exceptions, were more or less walk-on cameos and stopped by the show's fifth season, by which point all the established Degrassi Junior High actors sans Brogen had either left the series or had their roles significantly downplayed.
As Degrassi dropped The Next Generation part of its name, the show sent many of the alumni characters off with movie-length episodes after which many of these characters were never seen again. However, Shane Kippel reprised the role of Spinner Mason on several occasions throughout the show's remaining years.
Degrassi: Next Class let the show's legacy come through a bit more, as several older cast members came back more often to reprise their roles. Jamie Johnston had a semi-reoccurring role as Peter Stone while an episode titled #Throwback Thursday had several Next Generation actors come back to visit as part of an alumni weekend. All of this reached its peak in 2018, when Drake's video for his song "I'm Upset" featured many actors from Next Generation reprising their characters - ultimately becoming the last piece of Degrassi media to be filmed at the show's set in Toronto before it was sold off.
As a long-runner, Doctor Who has done this several times.
An amusing example of this is with Michael Kilgarriff as the Cyber-Controller; originally appearing in "The Tomb of the Cybermen" (though voiced by Peter Hawkins), when the character returned two decades later in "Attack of the Cybermen", Kilgarriff reprised the role in both body and voice.
It doesn't even have to be a special occasion. Troughton loved coming back for "The Five Doctors" so much that he gladly did "The Two Doctors" a couple of seasons later.
The 2005 revival includes Elisabeth Sladen reprising her role as Sarah Jane Smith in "School Reunion", and later in spinoff The Sarah Jane Adventures, which also featured guest appearances from Katy Manning as Jo Grant and Nicholas Courtney as the Brigadier, forty years after their respective era as regulars on the mothership series had concluded.
The 50th Anniversary led to an increased number of reappearances:
Paul McGann reprised his role as the Eighth Doctor for the mini-episode The Night of the Doctor", essentially giving his incarnation a proper send-off after 17 years of mystery over his regeneration.
In the special itself, "The Day of the Doctor", Tom Baker, the Fourth Doctor, made his first reappearance since departing the show, to the joy of many fans.
"Empress of Mars": At the end, the Martians are welcomed into the Galactic community by Alpha Centauri, with Ysanne Churchman reprising her "gay civil servant" voice 43 years after "The Monster of Peladon" and 24 years after her retirement.
Tommy Knight, Daniel Anthony, and Anjli Mohindra all reprised their roles nine years after The Sarah Jane Adventures ended for a special webcast epilogue for the spin-off series, which also featured Mina Anwar, Katy Manning, and Sophie Aldred.
"The Power of the Doctor", a special episode scheduled as part of the BBC's centenary celebrations, featured return appearances by multiple Doctors and multiple companions — most notably William Russell reprising the role of Ian Chesterton, one of the series' original regular characters, for the first time since he left the show nearly 60 years earlier — setting a new Guinness world record for longest gap between TV appearances as the same character.
The trailers for the Blu-ray season boxsets often feature companions reprising their roles (although usually after many years of playing them for Big Finish Doctor Who).
In addition to Bonnie Langford as Mel, the Season 24 trailer "A Business Proposal For Mel" featured the return of Catherine Cusak as Drinking Fountain, the Blue Kang leader from "Paradise Towers", and Edward Peel as an Iceworlder who might be a somehow-resurrected Kane from "Dragonfire". And Sylvester McCoy as the Doctor!
Julian Glover, who played Richard I in the 1965 Doctor Who serial "The Crusade", reprised the role in the 1982 TV movie adaptation of Ivanhoe.
Jon Lovitz reprised his guest role from eight years after his first appearance, revealing that his drug habits had since cost him his job.
After appearing as a Guy of the Week for Phoebe in Season 1, Hank Azaria reprised his role of David several times in the latter years of the show's run, first in a one-off appearance in Season 7, and then as a recurring character in Season 9 before losing out on Phoebe's affections to Mike.
Girl Meets World, the Sequel Series to Boy Meets World, features Ben Savage and Danielle Fishel reprising their roles as Cory and Topanga, now raising a family of their own. Additionally, characters from throughout the run of Boy Meets World have been brought back, always with the original actor playing them — with the sole exception of Cory's younger brother Josh, who is given The Other Darrin treatment (to be fair, he was a toddler at the end of the original show's run, and played by a non-actor to boot).
Season 2 has Paul Reubens playing the Penguin's father, a role he originated in the 1992 movie Batman Returns, though the character has a different name — nor is that the only difference ElijahVan Dahl has from TuckerCobblepot.
According to the commentary for Batman: Hush, Peyton List playing Ivy in the series actually falls under here, as producer James Tucker stated she'd recorded for the movie before she was cast to replace Maggie Geha in Season 4.
When the Hi-de-Hi! stage show went on a six-month tour in 2010, Barry Howard once more returned to the role of Barry Stuart-Hargreaves, which he had last played in 1986. His in-series wife Yvonne was played by Nikki Kelly, who had played Sylvia in the TV series (even if they wanted the original Yvonne - Diane Holland - back to join Howard, they couldn't; she had died the previous year).
iCarly (2021) sees Miranda Cosgrove, Jerry Trainor and Nathan Kress reprise their roles as Carly Shay, Spencer Shay and Freddie Benson from the original iCarly. Jennette McCurdy and Noah Munck opted not to return, so Sam Puckett and Gibby Gibson were simply written out. Other returns include Mary Scheer as Marissa Benson, Reed Alexander as Nevel Papperman, Danielle Morrow as Nora Dershlit, Tim Russ as Ted Franklin, Doug Brochu as Duke Lubberman (a minor character who hasn't been seen since the first season of the original show) and Drew Roy as Griffin. The second season brought more familiar faces back, including Jeremy Rowley as Lewbert Sline, Ryan Ochoa as Chuck Chambers, Ethan Munck as Guppy Gibson and Greg Mullavey as Granddad Shay.
Chae Shi-ra plays the older version of Queen Insu. Over ten years earlier she'd played the same role in the 1998-2000 series The King and the Queen.
Chae Sang-woo plays King Danjong. Two years later he played the same role in the 2013 film The Face Reader.
Michelle Jenner and Eusebio Poncela reprise their Isabel roles of Queen Isabella and Cardinal Cisneros in an episode of The Ministry of Time, even though it's a completely different genre and obviously not in the same continuity (for one, the actor who played King Ferdinand in the former is the main character in the latter: a Turn of the Millennium man that travels in time).
It's fairly common for past Kamen Rider characters to return in crossover movies and anniversary specials, though this is often done via Fake Shemps since many of the actors have moved on to other projects. The Kamen Rider Gaim film Kamen Rider Taisen is a notable exception, since it featured Hiroshi Fujioka reprising his role as the original Kamen Rider from way back in 1971, as well as Ryo Hayami reprising his role as Kamen Rider X and Shun Sugata reprising his role as Kamen Rider ZX. A number of the actors from more recent productions like Kamen Rider 555, Kamen Rider Decade, Kamen Rider W, and Kamen Rider Wizard returned as well.
The entire concept of multiverse in Kamen Rider Decade might stem from the fact not all of the 9 Heisei Riders' actors are available, especially Joe Onodera, not showing a single sign of willing to reprise the role of Yuusuke Godai, and Hiro Mizushima, who has seemingly have never been called back to reprise the role of Souji Tendou.
Kim's Convenience is based on a play; two members of the main cast, Paul Sun-Hyung Lee (Mr. Kim) and Jean Yoon (Mrs. Kim), reprise their roles from the Toronto Fringe Festival and Soulpepper Theatre versions of the play for the TV show.
Kung Fu: The Legend Continues: In the 1995 episode "Gunfighters", Clint Walker reprised his role of Sheriff Cheyenne Bodie from the 1955-1963 show Cheyenne. He had previously played Cheyenne in the 1991 film The Gambler Returns: The Luck of the Draw.
The reboot of Legends of the Hidden Temple has Dee Bradley Baker return to voice Olmec as he did in the original show, the TV movie adaptation, and the crossover with The Loud House.
Limitless has Bradley Cooper playing the recurring role of his character from the 2011 movie, acting as a sort-of mentor for the new protagonist.
Whatever Happened to The Likely Lads has James Bolam, Rodney Bewes, Brigit Forsyth, and Sheila Fearn all reprise their characters from The Likely Lads nearly ten years earlier. (Forsyth is a particularly interesting example, since she only appeared in one episode of the original series but is promoted from Girl of the Week to Bob's fiance.)
The L Word: Jennifer Beals (Bette), Katherine Moennig (Shane) and Leisha Hailey (Alice) all return to play their characters again in the Sequel SeriesThe L Word: Generation Q. Laurel Holloman (Tina) also appeared as did Rosanna Arquette (Cherie Jaffe) and Anne Archer (Lenore Pieszecki) in recurring or guest roles as their characters on the original show too. Daniel Sea reappears as Max in one episode in Generation Q's second season, now in a happy relationship with four children (three biological, one adopted).
In an example crossed with Casting Gag, the ending of Episode 5 features the surprise return of Evan Peters as Quicksilver, the role he previously played in the X-Men movies. What makes this such a surprise is that those films were produced by another studio (20th Century Fox) and are not part of the Marvel Cinematic Universe. It is later revealed, however, that Peters was merely playing a man who'd been brainwashed into thinking he was Quicksilver, explaining the lack of resemblance to Aaron Taylor-Johnson (who previously played Quicksilver in the MCU).
The 1980's revival of Mission: Impossible featured the return of Peter Graves as Jim Phelps. Additionally, Greg Morris reprised his role of Barney for a 2-part episode.
In the first arc of murder mystery series Miss Marple, 1984's "The Body in the Library", Gwen Watford played Miss Marple's friend Dolly Bantry. She returned to the role in the show's very last story, the 1992 Made-for-TV Movie "The Mirror Crack'd from Side to Side".
The 1987 Murder, She Wrote episode "The Days Dwindle Down" featured Jeffrey Lynn as Sam Wilson, a man falsely convicted of murder thirty years earlier, Martha Scott as Georgia Wilson, his wife, and Harry Morgan as Lt. Webb, the investigative officer on the case. These characters all appeared, played by the same actors, in the 1949 film noir Strange Bargain, which is used for Flashbacks.
Mystery Road: Along with Aaron Pederson playing Jay again, naturally, Mary (his ex-wife) is played here by Tasma Walton like in the film.
John Hurt, who played Quentin Crisp in the 1975 ITV biopic The Naked Civil Servant, reprised the role in the 2010 sequel An Englishman in New York ... which opens in 1975, with Crisp gaining new fame in the wake of the ITV film.
Now and Again: In the first act of the first episode John Goodman's character Michael Wiseman is killed in a subway accident and his brain is put into a new body, played by Eric Close. One episode of the series is told largely in Flashback and stars Goodman instead.
Olive and Otto left Odd Squad, and by extension the show, in the Season 1 finale "O is Not For Over", taking their respective actors Dalila Bela and Filip Geljo with them. Both Dalila and Filip would return a month later to reprise their roles for Odd Squad: The Movie. Additionally, Dalila would also reprise her role as Olive for the OddTube episode "Interview with Olive", albeit in a voice-acting position and not as a physical appearance like in the movie.
Olympia and Oona, as well as Anna Cathcart and Olivia Presti respectively, leave the show after the second part of the Season 2 finale, "Odds and Ends". Anna Cathcart would later go on to reprise her role in the OddTube episode "Welcome to OddTube Season Two!" in a similar voice-acting setting as Dalila Bela with Olive in "Interview with Olive". Olivia Presti, on the other hand, would reprise her role in two episodes of the show's podcast, the Odd Squadcast.
Once Frozen (2013) characters were introduced in Once Upon a Time, most foreign dubs had the voice actors from the local dubs of the movie reprise their roles.
In the Latin American Spanish dub, Dafnis Fernández and Georgina Sánchez once again return to voice Roronoa Zoro and Nami, respectively, from the anime.
The German dub brings back Daniel Schlauch as Monkey D. Luffy, Uwe Thomsen as Roronoa Zoro and Stephanie Kellner as Nami from the animated productions.
Still Open All Hours has Granville, Mavis, Mrs Featherstone and Nurse Gladys Emmanuel all played by the original actors, nearly 20 years after the previous series.
Raymond Burr and Barbara Hale reprised their roles from the original Perry Mason series in the TV movies, 19 years later.
Poirot: Eleven years after "Murder in Mesopotamia", the last episode to feature Hugh Fraser as Captain Hastings, the final season has him return for "The Big Four" and "Curtain: Poirot's Last Case" (both of which have Hastings returning after an absence in the original books). "The Big Four" also has Philip Jackson as Inspector (now Assistant Commissioner) Japp, who last appeared in "Evil Under the Sun" the year before "Murder in Mesopotamia".
Power Rangers and Super Sentai often has the previous years' cast reprise their roles for a crossover with the current Ranger team. It also sometimes brings back older characters into later series as semi-regulars. For example:
Almost all former Red Rangers, including Austin as Jason and Jason David Frank as Tommy Oliver, returned for Power Rangers Wild Force's Milestone Celebration episode, "Forever Red". The only Red Rangers not played by their original actors were Aurico (who was a Fake Shemp) and Rocky, who was absent completely. Bulk (played by Paul Schrier) and Skull (played by Jason Narvy) also returned.
In Power Rangers Samurai, Schrier would reprise as a main cast member, while Narvy reprised for a cameo in the season finale.
The Sentai equivalent, Hyakujuu Sentai Gaoranger vs Super Sentai, brought back three recent Rangers and two older ones: Daimon Tatsumi (Kenji Shibata), Gouki (Teruhide Takahashi), Miku Imamura (Mima Higashiyama), Yuusuke Amamiya (Daisuke Shima), and Soukichi Banba (Hiroshi Miyauchi).
Tommy would return as a series regular in Power Rangers: Dino Thunder, again played by Jason David Frank, and would reprise in Super Megaforce’s “Legendary Battle” and Super Ninja Steel’s “Dimensions in Danger”.
For the 15th Anniversary special, the show got 5 Rangers from previous series to return as part of a grand alliance of veterans. While four of these were from themostrecentseries, the team was led by Adam Park, a Ranger from the earliestdaysof the franchise. This required Johnny Yong Bosch to reprise the role for the first time in 9 years.
First, when MMPR was dubbed back into Japanese, Machiko was brought back as Rita's voice actor. It's not unheard of for Super Sentai alums to dub their Power Rangers counterparts like this, but this is one of the few if only times that the person dubs over all of their own old footage.
Power Rangers Megaforce, especially for the second half's finale, saw many actors reprise their roles, particularly from the Saban era. Its Japanese counterpart Kaizoku Sentai Gokaiger was an even huger example - there was at least one reprisal for each of the preceding 34 seasons of the franchise, from Naoya Makoto coming back to play original Red Ranger Tsuyoshi Kaijo to the entire cast of Tensou Sentai Goseiger reprising their roles in the Milestone Celebration movie.
For the thirtieth anniversary of the franchise, a standalone special Mighty Morphin Power Rangers: Once & Always brought back a variety of characters from the original incarnation of the series.
Quantum Leap (2022): In the original Quantum Leap, Susan Diol plays Beth Calavicci, Al's One True Love, whose marriage to Al is saved by Sam's actions in the series finale. In the 2022 reboot, which features Al's and Beth's daughter Janis as a recurring character, Diol returns as Beth.
Mac McDonald made three guest appearances as Captain Hollister in the first two series and then reprised his role as a Recurring Character in all but one episode of Series VIII, broadcast eleven years later.
Clare Grogan also made numerous appearances in the first two series as the original Kochanski and then returned for a brief scene in Series VI five years later.
Selby and Chen, Lister's buddies seen twice in Series 1, also return eleven years later for the premiere of Series 8 with the same actors. Alas, Petersen wasn't there to complete the trio, but is referenced more than once.
Norman Lovett also returns as Holly, beginning with "Nanarchy", having not played the role since Series II.
The Dave era, beginning with Back to Earth, sees all the main actors (except either Holly - even Chloë Annett makes a cameo) return, a decade after the end of Series VIII.
The Series XII episode "Mechocracy" features the return of Talkie Toaster, still voiced by David Ross some 26 years after "White Hole".
And "Skipper" sees the return of Lovett as Holly and McDonald as Hollister, 18 years after their last role reprisals.
Romper Stomper: Jacqueline McKenzie is Gabrielle once again, who's now risen to a corporate medical job, though her son's a Neo-Nazi thug like she had once been with. Dan Wyllie (Vic/Cackles) is back, and still a far-rightist, but now with those who present a more "clean cut" look (as he does now too). John Brumpton reappears as Magoo, who's now become a survivalist type living in a shack far out in the wilderness where he has tons of weapons along with far-right gear. However, he still works with other far-rightists (Vic included).
Sam & Cat was a spin-off/crossover/sequel series to iCarly and Victorious, so it was only really a matter of time before some of the actors from the parent show reprised their characters in this series. This resulted in Eric Lange as Cat's odd improv teacher Sikowitz appearing in #MommaGoomer, Liz Gillies as Cat's close friend Jade West, Matt Bennett as Cat's friend and crush Robbie Shapiro, and Nathan Kress as Sam's close friend and ex boyfriend Freddie Benson in #TheKillerTunaJump, and Danielle Morrow as crazy ex-iCarly fan Nora Dershlit, Reed Alexander as blogger and long time iCarly enemy Nevel Papperman, and Noah Munck as the loveable but idiotic Gibby Gibson in #SuperPsycho.
Additionally Original Series actors Leonard Nimoy and James Doohan reprised their roles of Spock and Montgomery Scott, respectively, during the series.
John Colicos reprised his Original Series role as Kor in Star Trek: Deep Space Nine, decades after playing him in the original series, alongside William Campbell as Koloth and Michael Ansara as Kang. Kor would become a recurring character in DS9, and Kang would return in Voyager. The same Voyager episode, "Flashback," had George Takei return as Sulu re-enacting elements of Undiscovered Country, which includes Grace Lee Whitney as Lieutenant Rand and a one-off background character in a more pivotal role.
Carolyn McCormick playing a memorable holographic character named Minuet in a first season episode, then reprised the role in a very brief but pivotal cameo 2 years later.
The role of the Borg Queen was first played by Alice Krige in Star Trek: First Contact. When she was brought into Star Trek: Voyager she was played by Susanna Thompson. In the Series Finale, however, Krige returned to the role.
The DS9 episode "Trials and Tribble-ations" begins with the Defiant picking up an apparent human in Cardassian space who turns out to be Arne Darvin, still played by Charlie Brill some 29 real-time years and 105 in-universe years after "The Trouble with Tribbles".
The episode "Watcher" has Kirk R. Thatcher reprise his iconic role of Punk on Bus, 36 years after Star Trek IV: The Voyage Home.
The third and final season features the respective returns of Levar Burton as Geordi La Forge, Michael Dorn as Worf, and Gates McFadden as Dr. Beverly Crusher, rounding out the core Star Trek: The Next Generation cast.

In a rare animated to live-action transition, Corey Burton reprises his role as the voice of Cad Bane from Star Wars: The Clone Wars, though Dorian Kingi physically portrays the character.

Diego Luna and Forest Whitaker reprise their respective Rogue One roles as Cassian Andor and Saw Gerrera. Alan Tudyk will also return as the voice of K-2SO in the second season.
Genevieve O'Reilly reprises her role as Mon Mothma, which she originally played in a deleted scene from Revenge of the Sith before going on to play the character again in both Rogue One and the Star Wars Rebels animated series.
William Sadler actually played The Grim Reaper first in an obscure comedy sketch show called Assaulted Nuts. Then came the more famous portrayal in Bill & Ted's Bogus Journey, after which he played the Grim Reaper for a third time in the Tales from the Crypt episode The Assassin, this time as co-host with the Crypt Keeper.
The pilot of The X-Files featured alien abductees Billy and Theresa, who returned years later in "Requiem", and even had some appearances in the following season. FBI agent Jeffrey Spender, after having apparently died in Season 6, came back horribly disfigured in one of the last episodes of season 9. All were played by the same actors.
Dear White People: Brandon Bell and Marque Richardson reprise their roles playing Troy and Reggie.
It's quite common for Ultra Series actors reappear as their characters in other series. Here some of the notable ones.
Return of Ultraman: For the first of many times to come Kohji Moritsugu and Susumu Kurobe reprise Dan Moroboshi and Shin Hayata respectively to team up and rescue Hideki Goh from the clutches of the alien Nackle.
Kohji Moritsugu returns as Dan again in Ultraman Leo, this time as Gen Ootori's mentor and captain of MAC.
Since Ultraman Dyna is the Sequel Series to Ultraman Tiga, many of the actors on the latter show reprise their characters, notably Hiroshi Nagano and Takami Yoshimoto as the now-married Daigo and Rena in the finale.
Ultraman X: Sota Aoyama reprises Kaito Touma in the show's celebration of the tenth anniversary of Ultraman Max. Additionally, Takuya Negishi, Kiyotaka Uji, and Yukari Taki return as Hikaru Raido, Shou, and Arisa Sugita respectively.
Some of the voice actors from the donghua and the audio drama adaptations of Mo Dao Zu Shi return in the Live-Action Adaptation to dub over the actors playing the characters they voiced. There's Lu Zhixing as Wei Wuxian, Bian Jiang as Lan Wangji, Qiao Shiyu as Wen Qing, Tang Shuiyu as Jiang Fengmian, and Qiu Qiu as Wang Lingjiao.
Other voice actors from either adaptation are also lending their voices in the The Untamed, but they're not playing the characters they previously voiced. For example, Wang Kai note Lan Xichen's audio drama VA voices Jiang Cheng, Su Shangqing note Jin Ling's donghua VA voices Jin Guangyao, Chenzhang Taikang note Lan Sizhui's donghua VA voices Xiao Xingchen, Liu Sanmu note Nie Huaisang's donghua VA voices Xue Yang, Liu Cong note Lan Qiren's donghua VA voices Wen Ruohan, and Zhao Yi note Jin Zixun's audio drama VA voices Nie Mingjue.
Hikaru Midorikawa and Toshiyuki Morikawa, who voiced Jiang Cheng and Lan Xichen, respectively, in the Japanese dub of the audio drama will return to voice the same characters in the Japanese dub of the live-action drama.

Lars von Trier's Riget was originally broadcasted as two seasons in respectively 1994 and 1997, and despite plans for a third series, the show was shelved indefinitely due to the death of some of the principal actors. Trier would however announce in 2020 that he was bringing the show back for a Grand Finale, called Riget: Exodus, in 2022, that that several of the actors from the original two seasons were set to reprise their roles after 25 years; these include:
Supernatural ran for 15 seasons. There have been a few actors returning after a lenghty absence.
Loretta Devine returns as Missouri Moseley in Season 13 episode "Patience" 13 years after her season 1 appearance.
Season 15 episode "Our Father Who Arent In Heaven" Jake Abel returns as both Adam Milligan and Michael for the first time since "Swan Song", over nine years ago.

The Grand Finale "Carry On" has Christine Chatelain returning as Jenny for the first time in 14 years since Season 1's episode "Dead Man's Blood".
" and the Season 8 trailer Jo Grant vs the Autons... Again?!
