2001: A Space Odyssey/Trivia

* Beam Me Up, Scotty/Stock Shout-Outs:
	+ ***"I'm afraid I can't do that, Dave."***
	+ "My god, it's full of stars!" — This line appears in *2001* the book, but not in the movie. Nevertheless, in *2010* **the movie,** it's claimed Bowman said this before entering the Star Gate.
	+ Any time jaunty classical music is used in a space setting, particularly Johann Strauss Jr.'s Blue Danube waltz.
* Cast the Expert: After failing to find a British actor who could play the Mission Control CapCom, Kubrick hired a real U.S. Air Force air traffic controller stationed in Britain. The interviewer from the BBC was also played by a real BBC newsreader.
* Doing It for the Art: Stanley Kubrick and Arthur C. Clarke spent enormous efforts into making everything as realistic as possible. The earth moving equipment seen on the Moon would *actually* work on the real Moon. Quite a few experts from NASA and IBM were asked to help design the sets.
	+ Clarke published a few lines from his diary from pre-production in the introduction of a re-issue of the novel. They include "rang Isaac Asimov to ask him about the biochemistry of turning herbivores into carnivores." (Asimov, besides writing science fiction, was a professor of biochemistry.) And they never even did anything with that...
	+ Kubrick required the compositing work to be done by a team of British animators painting traveling mattes by hand, frame-by-frame, to mask out each element, rather than using bluescreen. When production ended, most of them signed onto *Yellow Submarine* in order to work on something colorful after spending two years painting little black blobs.
	+ Instead of storyboarding the docking sequence, multiple model sequences were shot so Kubrick could *edit them down.*
* Enforced Method Acting: Douglas Rain was only given HAL's lines, not the full script - thus keeping the Creepy Monotone at all costs.
* Fake Russian: Brit Leonard Rossiter as Dr. Smyslov, the guy who grills Floyd about just what's going on at Clavius.
* 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.
* Life Imitates Art: In spite of the long Science Marches On listing below this, the movie features a brief sequence wherein HAL and Dave play chess together. This was years before computers were designed with the ability to play chess, and then later stacked up against Grandmasters.
* 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.
	+ Bowman's spacepod can be seen in the background of Watto's scrapyard in *Star Wars Episode I: The Phantom Menace*. Interestingly, the book *Inside the Worlds of Star Wars: Episode I* notes it as a "repair and maintenance pod of unknown origin".
	+ The model for Saturn was used for *Silent Running*.
* Science Marches On:
	+ 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.
* 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.
* What Could Have Been: Kubrick had allegedly asked Osamu Tezuka to work as a production designer for the film, but sadly, The God of Manga was far too busy with his own projects to oblige.
	+ Also worthy of note is that Kubrick approached the rock group Pink Floyd to do the music to the film (as well as the later Clockwork Orange), but they declined. Roger Waters later said not scoring 2001 was one of his biggest regrets. (Supposedly "Echoes" syncs up to the third act of 2001, try it out.)
	+ Early drafts had the ship powered by an Orion Drive.
