I've always admired him since Quantum Leap. Growing up in the UK, we got a lot of that stereotype square jawed American hero type, but he was unique with a fatherly presence and brains as well as brawn.

I am still annoyed his first scene on Star Trek: Enterprise wasn't him sat in the captain's chair and saying "oh boy...", and that they didn't even reference it when Dean Stockwell was in an episode.
