Robin Williams Sues Celebrity Lookalike

It takes more than hairy arms and a good Mrs. Doubtfire impersonation to be Robin Williams.

The comedian and actor claims a look-alike named Michael Clayton duped a reporter and a charity organizer into thinking he really was Williams.

Williams' federal lawsuit claims the look-alike's agent, Michael Pool, called reporters in September to set up an airport interview with Williams.

Star Tribune gossip columnist C.J. interviewed the man and wrote that he "knows how to settle down and blend in; when there's no movie, he changes the hair color. If that guy wasn't blond, he'd look just like Robin Williams, some travelers seemed to be thinking." She went on to quote "Williams" talking about Prince ("I've watched that guy. Even Mrs. Doubtfire gets excited") and said he sometimes mimicked a Minnesota accent.

"I was completely suckered," C.J. wrote four days later after discovering the man was really Clayton. "When Pool arrived with 'Williams,' I was surprised by the blond hair. My suspicions eased when I saw Clayton's hairy arms."

The lawsuit, which includes allegations of false advertising, also says Clayton duped a woman who was organizing a charity for the Punkin Center Rural Fire Department in Missouri. The lawsuit said Shirley Collins questioned whether she was really dealing with Williams until Pool put a man on the phone who launched into a Mrs. Doubtfire impersonation.

The lawsuit asks for an unspecified amount of money, and that Clayton impersonate Williams only if he tells people that he isn't really Williams.

Clayton's Web site describes his act and says he is commonly mistaken for Williams. Clayton and Pool did not immediately return phone messages left by The Associated Press.
