Kutcher lacks career confidence

Ashton Kutcher insists he doesn't hate critics who bash his lack of talent - because he shares their sentiments.

The 28-year-old star was a former model before making a name for himself in a string of dimwit roles including That 70's Show and Dude, Where's My Car?

He told Details magazine: "I'll read how sh**ty they think I am. I don't necessarily think all the critics are wrong … I don't think I'm that good.

"And they don't think I'm that good. So I'm not pulling that feeling out of my a**. They're just backing up that feeling that I already have about myself."

Kutcher claims he knows his limits when it comes to dramatic roles and insists that's why he dropped out of the running for Superman Returns.

He adds: "Could anybody f**king take me seriously as Superman? Let's be honest about that!"
