* This Creator/JohnCarpenter's first feature length film is mostly a slow parody of ''Film/TwoThousandOneASpaceOdyssey'' and other "philosophical" SF films. It ends with the main characters failing to convince an artificially intelligent bomb to not explode. Only two characters survive the blast. One is taken by a group of asteroids out of nowhere. The other? ''He surfboards down a planet's atmosphere on a piece of wreckage.''
* In a meta sense, the scene where an alien tries to push an astronaut down a shaft? That scene inspired the screenwriter, Dan O'Bannon,to write the script for what would eventually become ''Film/{{Alien}}''. That's right, this film '''inspired one of the biggest sci-fi blockbusters of all time'''.
