Robert Sallin, producer of "Star Trek II: The Wrath of Khan," tried to keep the film's script secret, but word got out about the plan for Spock's death. Fans were incredibly upset. The outcry may have helped lead to Leonard Nimoy's decision to return to the franchise for the next movie. Sallin kept this clipping from a Wall Street Journal article about the fan reaction. He even received an anonymous death threat from a misguided fan.
