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.

]]>Rob Riggle in the face.” Rob tells us — with a straight face — that Ashton actually chipped his tooth during their one big fight. But we’re not sure if he was serious. Although he does have a chipped tooth in the film, post fight. “I hurt a lot of people,” Ashton says. “I just should’ve let the stunt guy do everything, to be perfectly honest, and stick to just making jokes!”   Follow Zap2it on Twitter and Zap2it on Facebook  for the latest TV, movie and celebrity news
