Star Trek: Leonard Nimoy Wanted Dual Role In Star Trek V: The Final Frontier
Nimoy wanted to promote Sybok from half brother to twin brother so that it would enable him to play both parts.
"He did not say one word to me for quite a long time, other than 'Hello.' I found out later he had really, really pushed hard to have this be a double role, a dual role for him. 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 Bill wanted a separate actor, and he was right. We were very different people."Nimoy apparently kept his distance from Luckingbill during the shoot but became more friendly towards the end;
"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."Luckingbill also commented on Star Trek V being the least liked Original Crew film and the unjust criticism William Shatner receives for it's perceived failings;
''I know a lot of people criticize Bill for what he didnt do or what he did do. Bill invites that because hes just got a big life and he plays it big. But I found him absolutely wonderful. I liked Bill and, to this day, think he did a good job with that film. Hes a favorite guy of mine.''
