Jason Merritt/ Getty Images, Jemel Countess/Getty ImagesFox News' Bill O'Reilly's fame is based on his opinions, but he doesn't think too highly of the famous who share theirs.
The O'Reilly Factor host especially can't stomach Oscar winner Sean Penn.
When the Hollywood Reporter asked him if there were any actors whose political leanings bugged him to the point of refusing to see their movies, he responded, "Just Sean Penn."
"He's a great actor, and if you hire him, you'll get a good performance," he said. "I'm just not going to give a guy who gives aid and comfort to people like [Iran president Mahmoud] Ahmadinejad, Hugo Chavez and Saddam Hussein, when he was alive, my 10 bucks. That's my right as an American."
While he admits he won't advocate that everyone do the same—"It's a personal decision," he says—O'Reilly neglects to share whether he saw Mystic River, for which Penn also took home an Oscar. The film, however, was directed by his favorite celebrity, Clint Eastwood.
Who else does the right-wing king love, hate and love-hate?
O'Reilly loves Al Pacino, Eastwood "because he's a self-made guy" and Gene Hackman "because I've never seen him give a bad performance."
More surprising is his affection for Jon Stewart.
"[He's] very funny, very smart," he gushes. "He's a left-wing guy, but he admits it, so I got no beef with him."
In addition to more obvious people like Keith Olbermann, O'Reilly also has "beef" with Bruce Springsteen and sometimes George Clooney.
"We took on George Clooney over the 9/11 charities, and we were absolutely right, but Clooney does a good job with Darfur," he explains. "We took on Bruce Springsteen for things he has done at concerts because we want to know what his frame of reference is."
For the folks keeping score at home, O'Reilly likes Eastwood, Pacino, Hackman, Stewart, sometimes Clooney, the late Ron Silver, Katie Couric and Helen Thomas. He dislikes Penn, Springsteen, Olberman and sometimes Clooney. And let's not forget those former feuds with Jessica Alba and Rosie O'Donnell.
