Ashton Kutcher on 'Two and a Half Men': 'I'm Not Filling Big Shoes'

"Extra" was on the set of Ashton Kutcher's "Two and a Half Men," where the returning-to-prime-time star says he's not filling any big shoes for his part as billionaire Walden Schmidt. "I'm just playing the character written for me. And hoping some guy's gonna get off work and turn on his television on Monday, and take a load off."

The star, who has replaced Charlie's spot in singing the "Manly Men" theme song in the show's open, notes his new surroundings of being on the set of a sitcom. "You can't really screw around when you've got a live audience. You're either good or you're not and they're gonna let you know right away."
