Star Trek III: The Search for Spock Easter Egg - Director Cameo (Well, Sort Of...)

In the scene showing Scotty talking to Captain Styles of the Excelsior during the "Stealing the Enterprise" sequence, Scotty goes into a turbolift. The elevator voice who asks Scotty for the level he wishes to go to, billed in the credits as "Frank Force," is in actuality, TSFS director Leonard Nimoy.
