Poll: A Less "Over the Top" Original Captain Kirk (Alternate Casting)

Okay, so it is the mid-sixties and you are casting a brand new television series about the Starship Enterprise that is going to be called "Star Trek (1966)." This guy named William Shatner has auditioned for the part of series star Captain James Kirk, but you think that he's too "over the top" and campy in his performance. You want someone more dramatic and with more acting skills (dramatic, romantic, physical, and comedic abilities required). Which actor from that era would you choose? Note: He has to be at least 30 years old (and under 60) and active in Hollywood by 1966. Discuss here: http://www.imdb.com/board/bd0000088/flat/248446212
