A 1968 science-fiction film, written and directed by Stanley Kubrick, with help from Arthur C Clarke (who also wrote a novel version in tandem with the film's production), and inspired in part by Clarke's short story "The Sentinel". Nearly universally recognized by critics, filmmakers, and audiences as one of the greatest and most influential films ever made, of any genre.The film's story tracks long-term human evolution as it is influenced by unseen aliens. The unearthing of one of their artifacts on the moon leads to an ill-fated expedition being dispatched to Jupiter, culminating in a famously incomprehensible climax. (The novel offers a if not the explanation for the latter.)Still one of the "hardest" sci-fi films ever made, it is known for its very slow pacing and enigmatic plot. It's also the reason you see Thus Spoke Zarathustra paired with sunrises, and Blue Danube Waltz paired with zero-gravity.Clarke went on to write several sequel novels (titled 2010, 2061, and 3001) which mostly followed the film's continuity, and one of them was made into a movie as well (2010: The Year We Make Contact).
This film provides examples of:
Adaptation Expansion / The Film of the Book: Clarke's original short story, "The Sentinel", dealt only with the part about the Monolith on the Moon. Kubrick and Clarke then expanded the story into a film and book that were released simultaneously. Clarke stated the book should be credited as "Clarke and Kubrick", with "Kubrick and Clarke" credited for the screenplay. Unlike a Novelization, there are distinct differences between the two; for starters, Clarke's Discovery travels to one of Saturn's moons, while Kubrick's Discovery goes to Jupiter. The reason for this change was to avoid a Special Effects Failure: the film crew couldn't build a model of Saturn that Kubrick liked, so he changed it.
A.I. Is a Crapshoot: HAL goes rogue and murders the crew of Discovery because of a Logic Bomb accidentally created by his programmers. This became an archetypal example of "malevolent AI" in popular culture, especially since the film version doesn't adequately explain the reasons for his malfunction.
Alas, Poor Villain: HAL basically goes out begging for mercy and appealing to Dave's friendship while he is slowly lobotomized.
Aliens Steal Cable: In the novel, the "hotel" area constructed by the Firstborn to receive Bowman is based on TV broadcasts received by the Monolith. The hotel room is supposed to give Bowman an environment he's comfortable with, but in the movie the aliens clearly did not research things very well, because a room with lights in the floor looks intensely disturbing. They also put the bathroom mirror over the tub instead of the sink. In the book, there are other anomalies, such as writing that is blurry in close-up, and all the food containers have an identical substance that in no way resembles human food while still being perfectly nutritious.
All There in the Manual: Clarke's accompanying novel is actually better than the film in a lot of ways, because of the amount of time he spends elaborating on the more opaque aspects of the film.
And I Must Scream: The flash-cuts of Bowman's horror as he's taken Beyond The Infinite. The journey reduces him to a quivering wreck — then he appears in the alien hotel room. It appears that that will turn out to be Bowman's purgatory, but it's ultimately averted as Bowman Ascends To A Higher Plane Of Existence.
Battle Chant: Subverted with the hominids. When Moonwatcher's group first encounters another group at the waterhole, the two groups shriek and howl at each other until Moonwatcher's group retreats. Soon after, Moonwatcher's group has contact with the monolith. When the two groups meet again at the waterhole, the second group makes a cacophany, while Moonwatcher's group is silent. The second group mistakes this for weakness, and their leader charges. Moonwatcher easily clubs his foe to death, causing the second group to quail and retreat. Silence, in this case, proved more unnerving than bluster.
Cosmic Horror Story: This was the real reason for Kubrick's use of Leave the Camera Running and Mind Screw: to convey that space is an immense and hostile place in which humans are insignificant by comparison, where if we encounter aliens they'd be incomprehensibly advanced, refuse to explain themselves to us, and be interested only in using us as tools. Lampshaded in the out-takes book The Lost Worlds of 2001, which covers parts of the astronauts' pre-mission training. They are told simply to take lots of pictures and not to try too hard to make sense of what they see... and to hope their hosts (if any) are aware of their limitations.
Creepy Monotone: Inverted. HAL's voice isn't a monotone at all; while calm and unemotional, his voice is actually much more expressive than any other character. That's precisely why it's so damn creepy.
Cryonics Failure: HAL intentionally kills the three hibernating astronauts by forcing a malfunction in the coldsleep system; in the novel, he depressurizes the ship as Bowman attempts to wake all three of them.
Cukoloris: 2001 was the first movie to show computer monitors projecting their images onto the user's face. This is pure Rule Of Cool, because in order to get this effect in real life you'd have to be staring straight into the bulb of a projector. There were 16mm projectors behind all the flatscreens on the sets, so all Kubrick had to do was take the screens off.
Electronic Speech Impediment: When Bowman disassembles HAL's neural circuitry, it reverts to demo mode and sings "Daisy Bell" in an increasingly slow, distorted manner before finally shutting down.
Escape Pod: Technically, the EVA pods, although they are not used for this, and there would be no way to rescue them anyway, save sending another pod from the same vessel. They're more like Maintenance Pods, really.
Everything Is an iPod in the Future: Ur Example — the iPod was named after the space pods in this movie, and the white surfaces and black control panels on all of Discovery's equipment were an inspiration for its design. Similarly, the novel describes a device that is extremely similar to modern concepts of the tablet computer.
Evolutionary Levels: Self-evolution, but still mentioned - the Firstborn's status as Energy Beings is stated to be the ultimate stage in physical evolution. "And beyond that, there could only be God." The opening "Dawn of Man" sequence is about the Firstborn giving human evolution a kick in the pants.
Explosions In Space: In an aversion of the typical trope, the explosive bolts that decompress Bowman's EVA pod go off silently with just a puff of gas.
Explosive Decompression: Averted. (Though used in the literal, scientific sense in that Bowman went almost instantly from full external air pressure to vacuum when he blew the pod's explosive bolts.)
First Contact Math: In the novel, Bowman tries unsuccessfully to communicate with the Iapetus monolith by broadcasting primes at it. Unsuccessfully in this case because it already knows he's there and what it intends to do with him. There is some speculation as to whether the 1:4:9 ratio of the monolith's sides is significant in this respect; it is, but the details are never revealed.
Flip Flop of God: What exactly the orbital platforms are for. Originally they were intended to be nuclear delivery systems, but this was later retconned to leave their purpose ambiguous.
Food Pills: Meals include a collection of zero-gee liquids sucked up through straws, horrible-looking preprocessed sandwiches, and trays of (essentially) Astronaut Chow on Discovery. It all almost makes the raw tapir meat the ape-men eat at the Dawn of Man look appetizing. The book, on the other hand, has the food on Discovery be designed to be just like "real" food, including fresh baked bread, in order to help make the years long space trip tolerable.
Word Of God has it that the food in the movie was intended to resemble baby food, on the grounds that as far as space-faring civilizations go, the human race is extremely infantile. The three things all babies have to learn is how to eat, walk and control their own bodily functions. Space faring humans are shown taking baby-steps with Velcro shoes around the cabins of space liners, eating stuff that resembles baby food, and needing a lengthy instruction manual to use the space toilet (see Nobody Poops below) to highlight humanity's childlike status.
HAL: "Let me put it this way, Mr. Amor. The 9000 series is the most reliable computer ever made. No 9000 computer has ever made a mistake or distorted information. We are all, by any practical definition of the words, foolproof and incapable of error."
Lampshaded by Dave when he's discussing the HAL situation with Frank in the EVA pod. He points out that the statement about the 9000 series having a perfect operational record sounded rather too much like Famous Last Words for his taste.
In the sequel (for those who didn't read the original novel), the previous and following statements were proven true, making the foreshadowing truly epic, although the fate tempting loses a little credence.
HAL: "It can only be attributable to human error. This sort of thing has cropped up before, and it has always been due to human error."
Government Conspiracy: The U.S. government tries to cover up the discovery of the Monolith by cutting off all communication to Clavius Base, spreading rumors about an epidemic, and concealing the Monolith's existence from Dave and Frank.
The Great Politics Mess-Up: The USSR is surprisingly healthy in 2001. On the other hand, relations between the US and USSR are remarkably amicable, from the point of view of the 1960s. (Kubrick's previous film wasDoctor Strangelove.) They have built a huge space station together, and are generally cooperating in the exploration of the moon. The Russians being suddenly shut out of the Clavius moon base is seen as a very unusual event.
Hemisphere Bias: Although the Earth as seen from the moon looks unrealistically washed out (see Science Marches On), North America is always visible every time we see it.
Hitler Cam: The scene of Bowman unlocking the door to HAL's Logic Memory Center and crawling inside is shot from a worm's-eye-view: the camera is on the floor and Keir Dullea has to step over it. By making him look huge and threatening, Kubrick gives us the impression that Bowman is going on a Roaring Rampage of Revenge against HAL without him having to say anything.
Invisible Aliens: Sort of. While there is ample evidence for the presence of alien intelligences, neither humanity, nor Dave Bowman, nor the reader/viewer ever finds out what the actual aliens themselves look like. In the novel it's revealed that they had long since evolved into Energy Beings.
I Want My Jetpack: In 2001 we have manned interplanetary spaceflight, permanent bases on the Moon, suspended animation and sentient computers. Contrast with Zeerust below.
Leave the Camera Running: Often cited as one of the film's shortcomings, in the many lengthy shots (by today's standards).
Logic Bomb: Revealed in the novel (and the movie 2010) as the cause of HAL's malfunction. HAL is programmed not to keep secrets. And ordered to ensure that the human crew of Discovery do not learn about what is at Jupiter. So he sets about killing the crew.
Lzherusskie: Brit Leonard Rossiter as Dr. Smyslov, the guy who grills Floyd about just what's going on at Clavius.
Narrative Filigree: Many scenes, especially the middle. The subplot with HAL, which is the most memorable part of the movie, serves only to leave Bowman as the Sole Survivor, and it doesn't really have any connection to the Monolith plot except as a consequence of the Government Conspiracy.
No New Fashions In The Future: This is most obvious with the very '60s-looking womens' hairstyles, and the matching plaid suit and pants worn by the photographer at the moonbase.
Nobody Poops: Averted by Floyd when he has to read through the entire set of instructions for the Zero Gravity Toilet before he can use it.
Offscreen Reality Warp: This provides much of the Mind Screw in the hotel room scene at the end of the movie. Bowman is in the pod, then he sees a slightly older version of himself in his spacesuit outside the pod, then the pod disappears. From the bathroom, he sees an older version of himself having dinner, then when the middle-aged Bowman gets up to look in the bathroom, the spacesuited Bowman has disappeared. The middle-aged Bowman sees an even older version of himself in the bed, then he and the dining table have been replaced by the Monolith....
Oh Crap: David Bowman as he is taken Beyond the Infinite.
Dave gets three Oh Crap's in a row in the space of about a minute.... First, "I know you and Frank were planning to disconnect me." He tries to bluff, but then Hal answers, "Although you took very thorough precautions in the pod against my hearing you, I could see your lips move." Finally, the look on Dave's face when he realizes that he forgot his helmet.
"Dave, this conversation can serve no purpose any more. Goodbye."
HAL gets one of his own. "My mind is going... I'm afraid..."
Ominous Latin Chanting: György Ligeti's "Requiem" and "Lux Aeterna" are so ominous, you can't even tell they're in Latin anymore. (Or Greek, in the case of the Kyrie from the "Requiem"!)
Prop Recycling: Deliberately averted. Kubrick had all the sets, special effects models, and design notes destroyed after filming was complete, to prevent them being reused in low-budget B-movies. The production crew for 2010 had to rebuild everything by examining the film itself, frame-by-frame. A deliberate case of No Plans, No Prototype, No Backup.
It didn't work. Several models (rebuilt or maybe the same film clip) have been used. Space1999 used the same rocket landing site on the Moon.
Public Domain Soundtrack: Classical music, used brilliantly. There was a soundtrack by Alex North in the works for the movie, but until it was ready they used the classical music as a placeholder. Kubrick ended up liking the classical music version so much he never used North's compositions.
Besides technology progressing slower than the production team anticipated, there are two details of astronomy in this movie that have since become dated. Kubrick insisted that the artists paint the Earth very pale blue because its albedo is 0.38. Only a few years later, photos from the Apollo missions made everybody realize that this figure is averaged over the pure white clouds and the deep blue oceans. Jupiter and its moons were also intentionally depicted vaguely because of the limitations of ground-based telescopes.
The film's depiction of the lunar landscape owes much to the craggy, mountainous terrain that was common in science fiction before the Apollo landings. Nonetheless the film is surprisingly accurate given that the production predated even the Surveyor probes, let alone manned exploration.
Floyd and everyone else on the Moon walk around completely normally. The Apollo landings later revealed that a loping gait was required in the Moon's 1/6 gravity.
The proto-hominids in the opening sequence are all about the same size, but current theories and fossil evidence suggest that the males should've been substantially larger than the females.
During HAL's death scene, he sings a brief snatch of the song "Daisy Bell" ('Daisy, Daisy, give me your answer do...'); this was chosen because Arthur C. Clarke had, a few years previous, visited a Bell Labs demonstration of synthesized speech, which included singing the song in question, and was the first example ever of computer speech. This Shout Out is itself a frequent source of shout-outs in other films.
A wheel-shaped space station and an interplanetary mission jeopardized by Space Madness were previously seen in George Pal's Conquest of Space, released in 1955.
Show, Don't Tell: This is why the novel works so well as a companion piece. Whereas the film has astonishing visuals, the story is deliberately vague. The novel obviously can't show any visuals, so Clarke devotes a lot of time to explaining the backstory, the history of the technology in the film, and what's really happening with the prehistoric humans and Bowman after he enters the Star Gate.
Shrug of God: Certain ambiguous or unrealistic elements have been shrugged off by Kubrick and Clarke, such as the true meaning of the Monolith or how HAL was able to read lips from the side.
Silence Is Golden: Long stretches of the film have no dialogue, including the first 22 and last 24 minutes (not counting the overture and end credits/exit music).
Subspace Ansible: Averted, with a plot point in the novel being the length of time it takes the signals from the Monolith to travel around the cosmos. (If the signal had traveled instantaneously, the humans wouldn't have known it was directed at Jupiter.)
In the book, the signal is tracked by the impact of its wake on the probes that detect it. It was a tipoff to humanity to tell it where to look next, if it could.
Also averted in the film, when the BBC announcer mentions that his interview with Bowman and Poole edited out the time lag caused by the transmission from Earth to the Discovery.
Zeerust: HAL is a mind-bogglingly advanced, sentient computer, but can't print plain text onto looseleaf paper. Humanity in 2001 can build spectacular space-stations and has mastered interplanetary flight, but people are still using typewriters.
