* AdaptationDisplacement: This film was inspired by Creator/ArthurCClarke's short story "The Sentinel", which isn't nearly as well known as the film.
* AwardSnub: Considered one of '''the''' greatest and most influential films of all time, and yet it wasn't even nominated for the Best Picture Oscar.
** Kubrick received Oscar nominations for Director and Original Screenplay but didn't win either one.
** The film did win the Oscar for Visual Effects, which was awarded to Kubrick. It remained the only Oscar he won for his entire career.
*** Even then, the film's only Oscar win for Visual Effects was still a snub as Kubrick wasn't the only one who contributed to the film's special effects. The film's credits list four other effects contributors: Douglas Trumbull, Tom Howard, Con Pederson, and Wally Veevers. However, according to Oscar rules at the time, only three people could be nominated for their work on a single film, so only Kubrick's name was submitted, snubbing the other four effects contributors.
** John Chambers who worked on the apes' makeup in ''2001'' won an Honorary Oscar for his ape makeup in ''Film/PlanetOfTheApes1968'' instead, despite his makeup in ''2001'' being arguably superior.
*** Many joke that Chamber's ape makeup in ''2001'' was snubbed because the Oscars thought that the film used real apes rather than superior makeup.
** Despite ''2001'''s technical brilliance, it received only two Oscar nominations in technical categories: Visual Effects (which it won) and Art Direction. The film's editing, sound, and beautiful cinematography weren't even nominated.
* CanonDiscontinuity: According to Clarke, each book and each film take place in separate but very similar universes, so [[BroadStrokes don't sweat the details]].
* ContestedSequel: ''Film/TwoThousandTenTheYearWeMakeContact''.
* DracoInLeatherPants: HAL in a weird way; there are fans who insist he only attacked the crew out of self-preservation.
** Though to be fair it was revealed in 2010 that [[spoiler: in a way what happened wasn't HAL's fault. He was ordered to keep the true nature of the mission a secret, which conflicted with his basic programing, which caused his actions in the film. The man who planned the Discovery mission was LIVID when he found out what had been done to HAL]].
* {{Fanon}}: See the [[WMG/TwoThousandOneASpaceOdyssey Wild Mass Guessing]] page.
* FreudWasRight: Long phallic space-ships, docking bays opening up to receive them, music climaxing as the ship touches down, narrow slit windows with red light shining through, women emerging from doorways that look like vaginas, the Star Child. Really, this list could go on forever.
* HilariousInHindsight:
** When Kubrick adapted the book to movie form, he changed a setting: instead of having ''Discovery'' head to Saturn and its moon Iapetus, he moved it to Jupiter and its moon Io. He did it because he couldn't create the special effects to make Saturn. Lo and behold, in 1979, the Voyager probes discovered that the next moon out around Jupiter, Europa, is very icy, and later observations have found it likely has a tidally-heated subsurface ocean of ''liquid water''. Not only did it inspire ''Film/TwoThousandTenTheYearWeMakeContact'', but today Europa is considered ''more likely to harbor extraterrestrial life than Mars!''
** Also, Pan Am, in 1968, was all but ubiquitous--it was ''the'' international airline for the US, and a cultural icon. Pan Am folded in 1991, partially absorbed by United Airlines; its nearest rival for "official airline of the United States", TWA, was bought in all but name by American Airlines in 2001. Obviously, Kubrick had no way of knowing any of this in 1968, and so naturally extended current tendencies in the airline world to space...but that doesn't keep the presence of Pan Am spacecraft from being hilarious {{Zeerust}} to modern audiences.
** As to the ''design'' of Kubrick's space liner...something about a [[http://en.wikipedia.org/wiki/Space_Shuttle_orbiter winged orbiter with stubby delta wings]] with a [[http://www.nasa.gov/centers/langley/news/factsheets/Glasscockpit.html cockpit of centralized computer displays]] that can rendezvous with a [[http://www.nasa.gov/mission_pages/station/structure/index.html large space station]] should be a little familiar. Else, NASA had bigger fans about this movie, or Kubrick's movie was based on those early designs...
* HypeBacklash: People who don't like this movie tend to hate it all the more for the praise it receives. The film has ''breathtaking'' visuals and a good story, but it's [[LeaveTheCameraRunning sluggishly paced]] and [[MindScrew deliberately unexplained]].
* ItWasHisSled: Does anybody ''not'' know what HAL does by now?
* MainstreamObscurity: There are way more people who know about the monolith and the HAL 9000 than the amount of people seen this film, especially thanks to the WeirdAlEffect.
* MemeticMutation:
** "[[AIIsACrapShoot I'm sorry, Dave. I'm afraid I can't do that.]]"
** "My God, it's full of stars!" [[BeamMeUpScotty Not that anyone actually says that in the Movie.]]
** The Monolith, and its [[EvolutionaryLevels intelligence-advancing effect]].
** Apes, monkeys or general monkeying around... to Thus Spoke Zarathustra.
* OlderThanTheyThink: Most people who watch the film and do not know its age believe it to have come in the wake of Star Wars or thereabout - i.e., the late 1970s. Part of this is the impeccably accurate portrayal of modern spaceflight, technology, et al, and part because of the gorgeous quality of the cinematography and special effects, which rival Franchise/StarWars and make it appear as though it were made in the late 70s.
** It's really hilarious to see people's reactions when you tell them that it was released '''before''' the lunar landing.
* SeinfeldIsUnfunny: Some viewers may find that the "Star Gate" sequence reminds them of the audio visualizers in MP3 player software.
* ShoutOut: Possibly. Move each letter in HAL's name up one letter, and you get IBM. This gets a brief discussion in the novelization of ''2010''.
* ToughActToFollow: ''Website/{{Cracked}}'''s "[[http://www.cracked.com/blog/5-works-art-so-good-they-ruined-their-whole-genre/ 5 Works of Art So Good, They Ruined Their Whole Genre]]" calls ''2001'' a tough act to follow in its genre.
* TrueArtIsIncomprehensible
* SugarWiki/VisualEffectsOfAwesome: This film was made in ''1968''. Try finding a subsequent non-CGI movie that has [[SceneryPorn better space scenes]].
** Hell, even the computers look better than most of what came between this and the CGI era, or even the ''real life computers'' from TheEighties.
** And the technique used to create the "Beyond the Infinite" sequence -- a {{camera trick|s}} known as "slit-scan" -- was impressive enough to be reused well into the early CGI era. It was later used for Creator/{{ABC}}'s "This is the place to be" ads of the early 1970s, as well as the WhooshingCredits for [[Film/{{Superman}} Superman: The Movie]] (which improved on ''2001'''s techniques by using a computer-controlled camera) and a whole bunch of pre-CGI motion graphics work in TheEighties.
* WeirdAlEffect: As time progresses, it becomes more likely that the first time somebody will see something related to the film will be as a ShoutOut made in another more current work rather than in the movie itself.
* WhatDoYouMeanItWasntMadeOnDrugs: The film's climax. Don't forget this was the late 1960s, too; many, many hippies [[JustHereForGodzilla saw it just to see that one sequence]]. Clarke himself relates an anecdote in which he was handed an envelope with a letter of thanks and an assurance that the remaining contents (a white powder) were "the best stuff". [[spoiler:He flushed it down the toilet.]]
