Leonard Nimoy failed to speak to actor Laurence Luckinbill on the set of Star Trek V: The Final Frontier over the latter’s role as Sybok.
Speaking this week to Star Trek.com, Luckinbill says that Nimoy was absolutely determined that Spock and Sybok should be twins, and that he should play both roles.
However, when Nimoy didn’t get his way, he took it out on his co-star. He reveals: “He did not say one word to me for quite a long time, other than ‘Hello’, because, I found out later, he had really, really pushed hard to have this be a double role, a dual role for him. I don’t know if this is absolutely true.
“That was the scuttlebutt and I got that from very high up in the food chain of information, that Leonard wanted to play Sybok and play Spock. That would have been a tremendous thing, to do that, but since they weren’t twins, they cast me. I think that Bill [Shatner] wanted a separate actor, and he was right.
“We were very different people. The best compliment I got was, in the last scenes, 20 or 25 weeks later, Leonard looked at me and said, ‘You know, you’re terrific in this’. I thought that was a great send-off.”
Later in the chat Luckinbill spoke of his endless conversations with Shatner over Sybok’s motivations and innermost desires — until shooting began and Shatner told Luckinbull to shut up about the motivations now, because it was time to make the damn movie.
