Who besides Patrick Stewart and Colm Meaney have had great acting careers beyond Star Trek? Alexander Siddig has done okay... I might be forgetting one or two, but I think William Shatner is definitely in the top 5 as far as success outside of Trek. How many Trek actors have won emmy's for non trek roles? Or has enjoyed starring roles in multiple popular tv shows? Shatner has. I think Nimoy gave a better performance as Spock than 99% of trek actors, including shatner. Of course this is a matter of opinion.
