E.T. The Extra-Terrestrial was 1982's biggest movie at the box office, but it was a banner year for alien movies and the sci-fi genre. Movies like Star Trek II: The Wrath of Khan, Blade Runner, and Tron all featured aliens, advanced technology, or interplanetary travel, highlighting versions of a future that vacillated drastically between hopeful and altruistic to gritty and dark. E.T. was a family-friendly adventure from Steven Spielberg about a strange-looking but loving alien who crash lands on Earth and befriends a young boy and his friends who must help him get home before the government finds out about his existence.
