Soon after the release of Star Trek II: The Wrath of Khan, Leonard Nimoy took to the streets to quiz fans about Spock's death. Widely regarded as one of Star Trek's best films, The Wrath of Khan premiered in 1982 and set a world record for its first-day box office gross. Star Trek II saw the return of former Earth dictator Khan Noonien-Singh (Ricardo Montalbán), who had made his first appearance in Star Trek: The Original Series season 1, episode 22, "Space Seed." After Captain James T. Kirk (William Shatner) marooned Khan and his followers on a desolate planet, he mistakenly believed he'd seen the last of them.
