Director Clooney has star filmed naked

George Clooney says he had the star of his new movie filmed naked on the first day of shooting.

He is directing Confessions Of A Dangerous Mind, which stars Sam Rockwell.

The film is based on the autobiography of game show host Chuck Barris.

"The very first day of shooting I had Sam Rockwell standing completely naked in front of a TV set. That typifies the way the film is going," Clooney said.

Barris, creator of The Gong Show, claims to have been a covert CIA assassin.
