London, Feb 6 : American actor Steve Martin has insisted on using a stunt double on film sets, as he says his body is riddled with aches and pains from the active comedy roles he has been performing over the years.

Martin, 63, has been doing his own stunts for decades just to get a laugh after his career took off in the 1970s.

But now he has admitted that with age his body is slowing down and that he worries about the injury he might inflict himself.

"I worry now about being injured. You never get a major injury on a set (like new film Pink Panther 2), just little injuries that nag you for three years. I now use stunt men," the Daily Express quoted him as telling the New York Daily News. (ANI)
