who played young spock in star trek 3
Star Trek III: The Search for Spock Nimoy, in addition to his directing duties, appears towards the end of the film as Spock, but only appears in the opening credits as the director. Nimoy found the most difficult scene to direct was one in which Leonard McCoy talks to the unconscious Spock in sickbay, en route to Vulcan. Nimoy recalled that not only was he in the scene, but his eyes are closed, making it difficult to judge the quality of the shot or the actor's performance: "It drove DeForest Kelley crazy. He swears that I was trying to direct him with the movement and flutter of my eyelids." Nimoy was thankful the story required him to appear in a minimal number of scenes.[4] The rapidly aging Spock, at the ages of 9, 13, 17, and 25, was portrayed successively by Carl Steven, Vadia Potenza, Stephen Manley and Joe W. Davis. Frank Welker provided Spock's screams, and Steve Blalock doubled for Nimoy, so that a total of seven actors contributed to the role.[7]
