The animateds sound very dull, and I assumed it was because said actor was speaking into a mic inches away, rather than to an actor across the set. This could be true of Nimoy looping, yes? But I have always assumed it was a portrayal: he jsut got interrupted from the kolinahr and his awakening and hand-hold scene are integral to the movie. Which has so much character stuff I REALLY wish the stupid pacing wasn't an issue.
Anyway, regarding his sound NOW?? Come on, the dude's roughly 80 and 83 in those flicks? If I'm walking and breathing then, I'll be happy, much less acting in a big movie in costume and alien makeup. He sounds like an OLD Spock, which he is. No prob here.
