Ashton Kutcher may have mastered the role of the brainless male bimbo, a la “That ‘70s Show” and “Dude, Where’s My Car?,” but this savvy actor also knows how to capitalize off his Hollywood fame. The show Punk’d, his own creation, ended up being wildly successful. Kutcher is also executive producer for WB’s “Beauty and the Geek” and ABC’s “Miss Guided.” New to his credits is “Pop Fiction” and the 2008 comedy “What Happens in Vegas.” Kutcher is on a role, and he won’t slow down anytime soon.
