He may play one of TV's iconic characters in the upcoming Star Trek
movie, but Chris Pine believes he can add something new to the character of Captain James T. Kirk.
"No matter what your job, there are always ways to do something better than your predecessor," he tells the May issue of Men's Health
magazine. "That's why you were hired."
Not that commanding the U.S.S. Enterprise was an easy task. "When I started Trek
," he says, "I didn't have time for anything else but climbing the thing and getting to the top. There's tremendous responsibility. There's tremendous pressure. But all those just clarify your vision."
Tackling the role may have been daunting, but Pine knew he had to try. "I think the most dangerous word in the English language is should," he says. "'I should have done this.' Or 'I should do that.' Should implies responsibility. It connotes demand. Which is just not the case. Life ebbs and flows."
Lately, life has brought him to a happy place, complete with a sunny and optimistic girlfriend. Just one hitch: She's a morning person and he's not. "I'm so envious of that genetic wiring that immediately puts a smile on your face," he says. "My genetic wiring just puts creases in my eyebrows."
A buff Pine appears on the cover of the magazine, which hits the stands on April 21.
