Re: What guest stars would you have liked to see on TOS?
I think Michael Rennie would have been a class act for TOS. Just recently I've watched a couple of first season Voyage To The Bottom Of The Sea episodes. I can't help thinking it would have been cool to see Richard Basehart guest on TOS (despite the possible conflicting schedules) and also Canadian actor Lloyd Bochner as a heavy (he often played a heavy). He'd have made a great pain-in-the-ass Federation official.
STAR TREK: 1964-1991, 2013-?
