1. 'Star Trek II: The Wrath of Khan'
After the disastrous Star Trek: The Motion Picture, the people behind the franchise made the very wise decision to simply bring back a beloved villain from the old show and watch the sparks fly. Ricardo Montalbán was making Fantasy Island at the time and only had dim memories of playing Khan Noonien Singh on the 1967 episode Space Seed, but he was game to suit up and give it another go. The movie begins with Khan stranded on a barren planet with his army of genetically engineered warriors, blaming Kirk for all his problems. He steals a spaceship and sets off to gain his revenge, setting up a killer confrontation even though the two men never actually come face-to-face. Their interactions are completely though view screens. Khan died in the end, but he takes Spock with him. At least, that's how it seemed until the next movie rolled around.
