With Star Trek II: The Wrath of Khan, the series took a swing in the exact opposite direction from Star Trek: The Motion Picture, putting things on a raw emotional level. This is a sequel, not of the first film, but of an original “Star Trek” episode, “The Space Seed”, also starring Ricardo Montalban in the Khan role. Now, it is 15 years later, and Khan and his men are marooned on a desert planet which is slated as an experiment in the Federation’s Genesis project. This project is actually a bomb of sorts that can take any uninhabited planet and make it habitable for life as we know it, transforming it into a tropical paradise. Khan hijacks a small cruiser piloted by Chekhov (Walter Koenig) and the duel between Khan and Kirk (William Shatner), the man with whom he is filled with hatred, for control of the bomb and for sheer revenge. Nicholas Meyer directs.
