Shipped on 03/28/05.
Chuck Barris (Sam Rockwell) has it all -- a hot TV hit, "The Gong Show," and the love of a good woman (Drew Barrymore). But he's got one big secret: He's a CIA assassin who kills while purportedly escorting his game show winners on their vacation prizes. George Clooney directs and co-stars with Julia Roberts in this film based on the book of the same name, authored by the real-life Barris.
