Re: How easily do you recognize Trek actors w/out makeup?
Edit: The actor is Phil Morris, who's probably best known for playing Jackie Chiles on Seinfeld.
Phil's Trek history goes back to when he was a child, playing one of the Onlies in "Miri". His dad (Greg Morris) was electronics wizard Barney Collier on the original "Mission: Impossible", which filmed at the same studio during TOS' run.
