Acting and voice acting can be a fickle thing, but sometimes what can be simply corrected with The Other Darrin will not be possible; we call that the Actor Existence Limbo.
Actor Existence Limbo is when a Voice Actor worked on a series, but an incident caused the voice actor to be missing in action. Rather than replacing the VA, they make the character role unvoiced. So if that character is part of a piece of media that requires voice acting, reused lines from previous appearances would be possible at best. If the media were a video game, then said character would likely be an NPC if reused lines aren't enough.
One of the reasons why an Actor will be placed in limbo rather than replacing them is due to potential of bad publicity. Affairs can be called out by the press, possible grudges can happen between both sides. Simply put, an AEL can be harmful to those who enjoyed the actor.
When the character is plain killed off due to the Actor Existence Limbo becoming too much, it becomes a case of McLeaned. When the network does this, it is a Role-Ending Misdemeanor. See also Demoted to Extra and Fake Shemp.
- In 2011, after Gilbert Gottfried's Role-Ending Misdemeanor, the Aflac duck, whose annoying voice as he quacks out "AFLAAAAAC!" is pretty much his whole shtick, was in trouble, right? Wrong! The next ad with him was filmed in Silent Movie style. The ad ends with the duck hit by a train, oh no! ...but then we see him harmlessly stuck to its front. The whole thing was pretty much a Lampshade Hanging - he was silenced for the time being, and thought to be gone, but it's not over yet! He got his voice back when Dan McKeague took over.
- The very rare case of a TV production team willing to wait out Actor Existence Limbo is the reason Spartacus: Blood and Sand has a prequel in place of its second season. The lead actor of the show, Andy Whitfield, was diagnosed with cancer and the chemotherapy understandably made it impossible for him to portray his muscle-packed character for a while, so they filmed the backstory of all the other characters before Spartacus was forced to join the gladiator school. Unfortunately, the therapy didn't take, leading to the protagonist being recast for the rest of the show.
- The Muppets:
- Rowlf was for years unvoiced in movies and TV specials (or only made small grunts or laughs) after Jim Henson's death, since it was thought that he was the character that most resembled Henson.
- Henson's Dr. Teeth and fellow Muppeteer Richard Hunt's Scooter and Janice were in the same boat for the longest time as well.
- After Steve Whitmire was fired, Matt Vogel took over Kermit; Eric Jacobson took over the Newsman; David Rudman, who has performed many of Richard Hunt's roles for the past decade, took over Beaker; and Peter Linz took on Statler, Lips and Link Hogthrob. They have yet to find a new performer for Whitmire's iconic role of Rizzo the Rat.
- This was also the case for many of Henson and Hunt's Sesame Street characters. Ernie didn't start reappearing in new material until three years after Henson's death and other characters like Guy Smiley and Gladys the Cow have only recently started appearing with speaking roles again.
- When Earle Graser, who played The Lone Ranger on radio, was killed in a car accident in 1941, Brace Beemer was almost immediately picked by the show's producers to replace him. Since Beemer's voice was quite different to Glaser's, a story was quickly written in which the Lone Ranger spent five episodes recovering from serious gunshot wounds and unable to speak, so that listeners would either not notice the change in voice or put it down to the injuries.
- AkaSeka and Yume100, from the same publisher, left new versions of Yuichiro Umehara's characters Ono no Imoko and Hinoto, respectively, unvoiced while he was on hiatus due to illness.
- Murphy Guyer didn't return for Neverwinter Nights 2: Mask of the Betrayer, and Ammon Jerro suddenly became an unvoiced NPC.
- Bill from Left 4 Dead got McLeaned in the second game's DLC, since his VA was unavailable for nearly a year. Bill was also not voiced for the Crash Course DLC due to having no time left to record lines for the character since the DLC was so close to release. Zoey, Francis, and Louis all have new lines while Bill just reuses lines that were in the game before the DLC.
- Cagalli became unvoiced after Mobile Suit Gundam SEED Destiny in Super Robot Wars since Naomi Shindo refused to reprise her role, so any games requiring her role will be a NPC only. The only moment she is playable so far is Super Robot Wars K (because K is on the DS and lacks voices).
- Dearka's voice actor Akira Sasanuma was also missing in action since Destiny. This is extra confusing in Super Robot Wars Z, where Sasanuma is in the game as another SEED character, Andrew Waltfeld's Number One Martin Dacosta.
- Naomi Shindo returned to voicing Cagalli in Dynasty Warriors: Gundam Reborn and Gundam Extreme Vs. Full Boost.
- Due to Chikao Ohtsuka's death in 2015, Aletheia of Granblue Fantasy hasn't made any major appearances in events or received a 5★ upgrade out of respect for him. Aletheia did appear in the Glorybringer quest in 2018, but the audio used for the characters appearing in the quest were purely short voice clips, possibly reused.
- Subverted with Guilty Gear: when Zato-1's voice actor Kaneto Shiozawa passed away, the character remained in the series... technically. Zato-1 was losing control of his body to a sentient parasite named Eddie (voiced by Takehito Koyasu in the XX series), who continued to use his body and appear under that name after Zato's death. The character is referred to again as Zato-1 in Guilty Gear Xrd, due to Zato being revived between games by the Big Bad Triumvirate of the first installment, -SIGN-, though both Zato and Eddie are now voiced by Koyasu.
- Metal Gear:
- Kaneto Shiozawa, the Japanese voice of the Cyborg Ninja in the first Metal Gear Solid, died of a brain concussion after falling down a flight of stairs on May 10, 2000. As a tribute, his voice recordings from the original MGS were used for Metal Gear Solid 2 for the second Cyborg Ninja (who was actually another character), as well as in Super Smash Bros. Brawl.
- Takeshi Aono, the voice of Colonel Campbell, passed in 2012. Campbell had previously appeared with other members of the Metal Gear cast in Super Smash Bros. Brawl, where Snake was a Guest Fighter and could contact his support team via codec to discuss his opponents. When Snake returned in Super Smash Bros. Ultimate, it brought back the original codecs but no new ones were recorded for characters added since Brawl; with Aono's absence believed to be the reason for it.
- Isamu Tanonaka, the voice of Igor in Persona 3 and Persona 4, died in 2010 due to myocardial infarction. To work around his death, they re-used his previously recorded lines in Persona 4 for The Animation in 2011 and Persona 4: Arena, with the character being absent from Persona Q: Shadow of the Labyrinth and being replaced with Elizabeth and Margaret, based on the player's path. He was seemingly recast for Persona 5 with Masane Tsukayama, only for the new Igor to be revealed to be an impostor who had captured the real Igor, still voiced by Tanonaka's old recordings.
- Ulf Andersson, voice of Wolf in PAYDAY 2, damaged his vocal cords while recording a Christmas carol for the game in late 2014. The recovery process took about a year, during which he announced he would be leaving Starbreeze Studios to found a new company. Edited versions of his present lines are used anytime an update adds content that requires more dialogue.
- Super Smash Bros. Ultimate could not use an English voice for Cloud Strife because his regular voice actor Steve Burton is the only one legally allowed to voice the character in English, but the game is a non-union project and Burton can't get around a union loophole since his contract bars him from working under a pseudonym or going uncredited. As a result, the game uses the Japanese recording for Cloud.
- When one of Dragon Ball Z Abridged's voice actors, Vegeta3986, left the team, the character he voiced, Yamcha, was given no lines to say. Rather, when he would try to speak, other characters would immediately cut him off, because they don't care what he thinks. This continued until he was recast to be voiced by Faulerro.
- Due to having numerous Celebrity Voice Actors, The Batman reduced many villains to non-speaking roles after their debut episodes. Poison Ivy, however, was featured prominently in a two-parter without any lines at all.
- Bojack Horseman: Abe D'Catfish, a minor character brought in after Kelsey's firing from Secretariat 's biopic, featured Garry Marshall as his VA for a Casting Gag/Self-Deprecation nod by playing a hack director and a stand-in of how watered down the once gritty project had become. Early season 3 deals with its premiere in film festivals, but Marshall passed away before recording could begin. Now what? How about having his last cameo set in his native Pacific Ocean City with bubbles muffling his speech? That'll do it!
- After already being replaced once, Valmont in Jackie Chan Adventures is reduced to a nonspeaking cameo in Season Five.
- The Simpsons:
- After Phil Hartman's death in 1998, his characters Lionel Hutz and Troy McClure were reduced to cameos in group shots. However, Troy McClure and Lionel Hutz both continue to appear regularly in the comics, since a voice actor is not necessary.
- Likewise Marcia Wallace as Edna Krabappel.
- After Doris Grau's death in 1995, Lunchlady Doris also became a mute background character, until 2006 when she returned, voiced by Tress MacNeille.
- A coincidental example in Avatar: The Last Airbender. Before Mako's sad passing, several episodes were written in the first half of Season 3 where Iroh was imprisoned and largely silent, which wound up serendipitously working out. His replacement actor Greg Baldwin briefly voiced a few lines in Season 2 to get viewers used to his new voice before the character fully returned later, and Baldwin does a good enough impression of Mako that those not in the know might not even have noticed (it helps that Baldwin was a self-taught Mako understudy before the latter's death).
- Jazz and Cliffjumper stopped appearing in The Transformers when Scatman Crothers fell ill and Casey Kasem quit. What made their disappearances ironic is that they were two of the very few season one characters who survived the infamous movie.
- The cast of Star Trek: The Original Series, minus James Doohan, appeared in the Futurama episode "Where No Fan Has Gone Before," but since DeForest Kelley had died, he had no lines.
- After its cancellation by Fox and resurrection by TBS, Mike Barker left American Dad! over "creative differences." Since then, while Terry Bates still appears in the show, he has not spoken a line since Season 12, Episode 3. Eventually he's Put on a Bus, leaving Greg to follow a tour across the country.
- In Steven Universe, fusions tend to be voiced by famous singers, such as Nicki Minaj and Aimee Mann. Due to the obvious difficulty in getting characters voiced by people in a field known for constantly traveling to be recurring characters (as well as the potential salary issues involved), fusions are rarely used despite their many abilities, and are often silent outside their first appearance, such as in the case of Opal, who hasn't had a single line since her debut. This receives a Lampshade Hanging in "Know Your Fusion," where Sardonyx actually breaks the fourth wall to ask if they'll have to pay "her" for using recycled sound bites from Sugilite's previous appearance.
- Family Guy: After Carrie Fisher's death in 2016, her recurring character Angela was retired from the show, and a new character played by Bryan Cranston replaced her as Peter's boss.
- On Cyber Chase , Slider's father Coop was voiced by Tony Hawk in "Measure For Measure". Subsequent episodes have the character silent, mostly because he appears in cameos, and they wouldn't get a big name like him for a brief cameo in a Canadian show.
- In The Fairly Oddparents, the voice actor for Trixie Tang retired prior to Season 9, which has resulted in Trixie at best being occasionally seen in background shots, but not voiced.
- Nemo, Francines cat, becomes a permanent non-speaking character after Season 19 due to the passing of voice actor Greg Kramer in 2013. The S19 finale The Last Day was dedicated to him.
- Principal Haney also gets written out following the death of his voice actor Walter Massey in 2014. The shows writers likely felt recasting him would be in bad taste. Season 19s opening episode Brain Sees Stars was dedicated to him.
- Sofia the First: Grand Mum appears in the series finale after her voice actress Florence Henderson's death but has no lines.
- DC Super Hero Girls has a large cast of characters and episodes usually running for 2-4 minutes. It's because of this not every character will speak when they appear. Some standout examples include Wonder Woman's Hero Of The Month episode (which has the distinction of being the only HOTM episode where the honored hero doesn't speak), "Ha Ha Horticulture" (everyone at school that's not Harley and Ivy falls asleep due to Ivy's plant serum going wrong, but Principal Waller is the only person who speaks when waking up), and "Mood Ring" (of the eight characters affected by Star Sapphire's broken Violet Lantern ring, only Batgirl, Harley, and Grodd speak).
- Justice League Action follows this idea the same way DC Superhero Girls does. For example, of Zatanna's nine appearances in the series (including the shorts), she only speaks in four of them. Two episodes had Batman being respectively controlled by Poison Ivy and captured by the Joker, but he doesn't get a single line.
