William Shatner has said that he wants to be Canada's prime minister, a role that won't give him much of an opportunity to play many scenes with a torn shirt.

We have no idea whether he'll ever actually get the job, or if he's even serious. But one thing we're sure of is that if he does decide to make a run for it, he'll join a long list of actors who've appeared in a sci-fi movie or TV series and later made a run for office.

Win or lose, here are the 10 most prominent politicos:
