Star Trek II: The Wrath of Khan (1982)
"Khaaaaaan!" Ricardo Montalban reprises a role from the original series, looking for revenge over Kirk and the crew of the Enterprise. Surely William Shatner's finest hour, and easily the best of the Star Trek series. Who will ever forget Spock and Kirk's exchange: "The needs of the many, outweigh the needs of the few... or the one"?
