Ten years after the events of failed Discovery 1 mission, Heywood Floyd is now working as a professor. He is approached by Dimitri Moisevitch, who explains to him that the Soviet Union is almost ready to launch another expedition to Jupiter, and proposes that a group of Americans should be brought to examine the Discovery and possibly find out why HAL malfunctioned.
- Stanley Kubrick had all models and sets from 2001: A Space Odyssey destroyed to prevent their reuse, thus the model of the spaceship Discovery had to be constructed from pictures.
Differences from the NovelEdit
- In the novel Hal repeats the words: "All these world are yours except Europa. Attempt no landings there." The movie adds the words "Use them together. Use them in peace."
