Good heavens! Drew Carey's (search) a Republican.

And great Caesar's ghost - so is Pat Sajak.

And you know who else? Ray Romano's TV wife - Patricia Heaton (search).

Well, I'll be a monkey's uncle - there are Republicans all over the darn place, reports a new documentary premiering tonight on AMC.

The revelation that not all celebrities march in liberal lockstep with Susan Sarandon (search) and Barbra Streisand is not exactly earth-shattering news.

What is newsworthy about "Rated R: Republicans in Hollywood" (search) is that a liberal Democrat could make a documentary about the conservative opposition that is so well-mannered.

The filmmaker, Jesse Moss, politely allows his interview subjects to explain their positions eloquently and at length. And at the movie's end, he even announces that he actually liked the people he interviewed, as if that were a huge surprise.

Given all the vitriol that has been spewed lately by the Bush-hating lefties in support of John Kerry, the views held by the interviewees in "Rated R" come as gusts of fresh air, as when Heaton describes the reaction at a Beverly Hills dinner party when she announced she and her husband both voted for President Bush.

"Literally," laughs Heaton, "you would have thought I had crapped in the middle of the table!"

With Republican movie star Arnold Schwarzenegger's (search) successful run for California governor as a jumping-off point, the film attempts to trace the origins of Hollywood's liberal-conservative divide back to the era of the McCarthy blacklists, which Sajak casually and refreshingly dismisses.

"We're a very forgiving nation," Sajak notes. "We have forgiven the Germans [and] we have forgiven the Japanese for bombing Pearl Harbor, but we just can't forgive that blacklist! ... It's as if McCarthy's prowling the hallways here and is going to come out and go, 'Boo!' one of these days."

Heaton complains that "civil" conversation on political topics is not possible in Hollywood. However, this documentary shows that it is possible, at least this once.
