He may be a movie star now, but Johnny Knoxville isn't ready to give up his Jackass persona, because he's having too much fun.

Knoxville's new movie THE DUKES OF HAZZARD sits atop the US box office chart and a slew of movie offers are set to head his way.

But the 34-year-old is determined to continue putting his life and health in danger - even though he knows he shouldn't.

Knoxville, who recently rejoined Jackass pals Steve-O and Chris Pontius on their show WILD BOYZ for tours of Russia and Argentina, says, "I should quit, but man we have so much fun."
