'Killers': Ashton Kutcher knocked out a stunt man

 

Ashton Kutcher vowed to get serious about his movie stunt fighting after accidentally knocking out a stuntman on the set of his latest film, "Killers."

He stars with Katherine Heigl as his new bride and Tom Selleck and Catherine O'Hara as his in-laws in this action-packed romantic comedy about a former international hit man whose wife has no clue about her husband's past.

Ashton tells The Dish Rag, "I bought one of those exercise DVDs off the TV. I put it in and watched it, and got in shape. I did some fight training. I learned Krav Maga, Muay Thai and Kali, which is Filipino knife-fighting. and then I realized I should learn how to movie fight because, in the first fight scene, I knocked out a stunt guy.
