* AlternativeCharacterInterpretation:
** Is Travis a "rebel with a cause" who targets Palantine mistakenly...or is he dissolving into insanity, and his rescue of Iris is just him looking for a justification for his desire to give in to violence? Or perhaps both...? For that matter, we never actually learn what is wrong with Travis. He shows signs of [[UsefulNotes/AspergerSyndrome Asperger's Syndrome]], schizotypal personality disorder, and [[HeroicBSOD post-traumatic stress syndrome]] (possibly from his time in Vietnam), [[AmbiguousDisorder but it's not clear which if any disorder he actually has]] or how it/they influence(s) his deteriorating mental state.
** Is returning Iris back to her parents a really heroic action? Iris claims that her parents hate her and that she ran away from home. She might be lying but given the tone of the letter at the end where the parents promise to make sure that Iris never leaves them again, one wonders if she was fleeing AbusiveParents and Travis has in fact returned her back to them. [[FridgeHorror How bad must her previous life must have been that she favours her current life as a drug-using child prostitute?]] For that matter, can we even trust what Iris tells us about her life?
** Did Travis Bickle live, or was the last scene a dying dream?
* AwardSnub: Lost Best Actor (Peter Finch) and Best Supporting Actress (Beatrice Straight) to ''Film/{{Network}}'', Best Original Score to ''Film/TheOmen1976'', and Best Picture to ''Film/{{Rocky}}''. Creator/MartinScorsese wasn't even ''nominated'' as Best Director. Neither was Creator/PaulSchrader for his brilliant screenplay. Considering that year was amongst the most competitive in the history of the Oscars, the Oscar losses might be justified or debated against.
* SugarWiki/AwesomeMusic / EarWorm:
** The title theme.
** In fact, the score overall. Music/BernardHerrmann's last and best work.
* FridgeBrilliance: Easy Andy tells Travis a great deal about the guns he's buying, but it's all very inaccurate and leaves one wondering why an arms dealer wouldn't know his own merchandise. Then one realizes Travis probably doesn't know anything about the history of the merchandise he's buying and Andy is just telling him this stuff to convince him to buy it.
* HarsherInHindsight: Knowing about the real-life [[https://en.wikipedia.org/wiki/Bernhard_Goetz Bernie Goetz]] case (which happened eight years after the movie came out) can make watching Travis' shooting rampage much more uncomfortable.
** Travis considers assassinating Presidential candidate Palantine, which would infamously be mirrored by John Hinckley Jr trying to kill President Reagan to impress Jodie Foster.
* HilariousInHindsight:
** Wizard's line about California being more progressive than New York when it comes to gay marriage is rather funny since, of the two states, New York legalized gay marriage first.
** Travis mentions "moonlighting". Years later, Cybill Shepard would star in ''Series/{{Moonlighting}}''.
* MisaimedFandom:
** The film has badly suffered from being idolized by gun-toting sociopaths who believed they'd found their representative in Travis (most infamously John Hinckley Jr). The other side of the fandom is nutjobs who take Travis' racism and vigilante ways as something to be admired. Like ''Film/AClockworkOrange'' five years earlier, a brilliant work of art that suffered because it was viewed by dangerous idiots.
** There are also those who use his famous "You talkin' to me?" scene as a sort of BadassBoast, when in context Bickle's just talking to himself and fantasizing. Specifically he was irritated by how stupid he came across interacting with secret service agents and wanted to be commanding and intimidating in his next interactions. [[DirtyCoward Eventually, he flees when said secret agents spot him and chase him]].
* NeverLiveItDown: John Hinckley trying to emulate Travis by shooting Ronald Reagan to impress Creator/JodieFoster. Not that any sane person would ever see that link otherwise, though.
* OneSceneWonder: Creator/MartinScorsese's cameo as a psychopathic passenger that Travis picks up. Apparently Scorsese never planned to be in the scene, the actor they hired got sick on the day of the shoot and so Scorsese had to step in.
** Easy Andy the gun salesman.
* TheProblemWithLicensedGames:
** A never released video game was in the works. According to [[http://rpgcodex.net/phpBB/viewtopic.php?p=1005431#1005431 to one]] [[http://rpgcodex.net/phpBB/viewtopic.php?p=1005870#1005870 of the staff]], it was going to be a ''VideoGame/GrandTheftAuto'' Clone, written by Hollywood Writers who had never played a video game or seen the movie (beyond the mirror scene) before. [[http://rpgcodex.net/phpBB/viewtopic.php?p=606445&highlight=taxi+driver#606445 Featured stupid dialog with awful voice acting]] and made Travis a mass-murdering psychopath instead of a deranged loner posing in the mirror. It even went through a period where the license was removed from the game before getting it applied again.
** Creator/PaulSchrader has noted that he and Scorsese have regularly halted, blocked and stalled attempts to license ''Taxi Driver'' spin-offs.
---> ''"We really have fought over the years to keep people's hands off Taxi Driver, to keep it from being a video game and to keep it from having a sequel. It's a one-off kind of film."''
* RewatchBonus: Could the[[spoiler: reunion with Betsy]] possibly be a hallucination Travis conducted?
* SpiritualAdaptation: Of Literature/NotesFromUnderground and parts of Literature/CrimeAndPunishment. Both Creator/PaulSchrader and Creator/MartinScorsese were great admirers of Creator/FyodorDostoevsky and Schrader described Travis Bickle as an American version of the "underground man" featured in Dostoevsky. Scorsese had wanted to adapt ''Notes from Underground'' himself before coming across Schrader's script and feeling that no direct adaptation could beat it.
* TheWoobie:
** Travis fuses this with JerkassWoobie. Sure, he may be a violent, misguided VigilanteMan, but after being spurned by his crush, mocked by the one he's trying to help, and generally disturbed by his own surroundings, it's impossible not to feel for him to some degree.
** Iris and other child prostitutes who are totally used to that kind of life and cynical enough to be skeptical of such would-be rescuers as Travis. Suffice to say seeing that bloody rampage committed by Travis will give her nightmares for years and years, in addition to her time as a prostitute and her ([[UnreliableExpositor supposedly]]) abusive parents, whom she says she ran away from and Travis returned her back to.
* WriterInducedFanon: Travis Bickle is never explicitly identified as TheVietnamVet, but the hints are there in his overall behaviour and jackets, the social context of 70s New York and the mention of him being in the Marines and a charred NVA flag in his apartment. Nonetheless Martin Scorsese considers him to be a ShellShockedVeteran returning from Vietnam. Creator/PaulSchrader, for his part, while never opposing this interpretation, kept it intentionally vague because he modelled the character on his own personal breakdown and embellished it with more general feelings, so as to lend the film to considerable {{Applicability}}.
