Across all media:
- Similarly Named Works: It can get pretty confusing if you're looking for the Luc Besson movie and get Judd Hirsch instead. Or looking up the pinball machine and wondering how to pick up Andy Kaufman as a passenger...
For the television series:
- Actor Allusion: There were a number of in-joke references to Andy Kaufman's stand-up act, including having his alter ego Vic Ferrari sing the "Mighty Mouse" theme.
- Actor-Shared Background: Tony Danza was an amateur boxer prior to appearing on Taxi.
- Adored by the Network: While Taxi was one of the "bottom 10" shows of the 1981-1982 television season, somehow NBC saw a worthy product in it and Un-Cancelled the show after ABC dropped it. Unfortunately, it "fared" no better with viewers on its new network and NBC was forced to cancel it (neither Cheers nor Family Ties got better numbers, but were spared by their numerous Emmy nominations; both wound up running much longer than Taxi).
- The Cast Showoff: Kaufman was able to perform dead-on impersonations of both Judd Hirsch and Tony Danza at some point during the series' run, in addition to creating the Vic Ferrari persona.
- Channel Hop: From ABC to NBC in its last season. Ironically, the show which beat it in the ratings during the third season on NBC, Diff'rent Strokes, moved to ABC during its eighth and final season.
- The Character Died with Him: Victor Buono played Jim Ignatowski's father in one episode. When he died, they killed off the character as well.
- Creator Backlash: The cast despised it whenever Andy Kaufman played Tony Clifton on the show because Kaufman refused to break character and acted as boorishly as humanly possible to everyone. It got to the point where everyone banded together and threatened to revolt if Kaufman wasn't fired immediately. The producers managed to come up with a compromise where they called Tony Clifton into a cast meeting, fired him, and had security guards physically throw him off the lot. This ensured that Kaufman couldn't bring the Clifton persona back onto the show and satisfied the rest of the cast enough to keep on working with Kaufman.
- The Danza: Tony Danza played Tony. (Trope Namer Ur-Example, since this was Danza's first role.)
- Jeff was played J. Alan Thomas; the "J" is for Jeffrey.
- Directed by Cast Member: Danny DeVito (3 episodes).
- Doing It for the Art: After ABC cancelled the show in 1982, HBO made a bid to pick it up. At the time no cable network had even aired a sitcom before (mostly because almost no one had cable back then), which would have made for a very daring (and risky) move. However, Paramount decided to have Taxi on either CBS or NBC, the latter of which ended up airing the show in its final season.
- Enforced Method Acting: One episode called for Louie DePalma to whisper something to Elaine Nardo, and for her to respond by slapping him and saying "That's disgusting!". Danny DeVito whispered such sweet things to Marilu Henner during rehearsals that she was genuinely shocked when he started whispering not-so-nice things, and she blew several takes because of it (to DeVito's delight).
- When Carol Kane joined the cast as Latka's girlfriend Simka, Andy Kaufman taught her their country's "language" by inviting her to dinner and refusing to speak English or let her do so.
- In one episode, guest star and real-life boxer Carlos Palomino accidentally delivered a real left hook to Tony's face. You can see Palomino pull his hand towards his mouth in horror for a second on realizing what he did before getting back in character and turning around to exit.
- Playing Against Type: Ted Danson turns up in one episode playing an arrogant Jerk Ass hairdresser.
- Reality Subtext: Andy Kaufman's character develops multiple identities? You don't say!
- Real-Life Relative: Louie's girlfriend Zena was potrayed by Danny DeVito's real-life wife Rhea Perlman.
- Also, DeVito's own mother Julia appeared as Louie's mom in a few episodes.
- Tony Danza's son Marc Anthony appeared in two episodes of the second season, appearing in one as the kid Tony wanted to adopt.
- Averted with Christopher and writer David Lloyd, with both being unrelated. Ironically, David is the father of another (also unrelated) Christopher Lloyd.
- Screwed by the Network: An unintentional example. To boost the show's ratings, ABC placed Taxi for its third season on Wednesday, opposite NBC's hit show, Diff'rent Strokes. To be short, ratings dipped considerably (but not to the extent of Soap, which, by competing with The Facts of Life, hit rock bottom and was swiftly canned).
- Star-Making Role: For Hirsch, DeVito, Danza, Kaufman and Lloyd.
- Troubled Production: Andy Kaufman never took the show seriously and often made ludicrous demands, most notably his showing up to the set in-character as Tony Clifton and causing utter chaos. To a lesser extent, Jeff Conaway suffered from a heroin addiction that kept leaving him unable to work for long periods, until he was fired.
- Un-Cancelled: The show was abruptly cancelled by ABC after its fourth season, but it was picked by NBC for another year before being cancelled for good.
- What Could Have Been: The Season 1 episode "A Full House for Christmas" was supposed to guest star Tony Clifton as Louie's brother, but Clifton's behavior on the set was so awful that he was fired; he wound up being escorted off of the Paramount lot.
For the movies (original and remake):
- Fake Nationality: Swedish actress Emma Sjöberg as German policewoman Petra.
