I saw him at a con in the late 80s.
By way of concession, when responding not so enthusiastically to questions from the audience about the shenanigans Shatner and Nimoy got up to in order to blow off steam during long shooting days, Doohan said that since he’d been in real combat in WW2, he had a different approach to work and not a lot in common with them.
Isn’t that what the sitcom Tawny Newsome is developing will be?
