Fox News host Bill O'Reilly slammed filmmaker Michael Moore and actor Seth Rogen on Wednesday, arguing that their professional prospects have suffered because they criticized the film American Sniper.

"I believe that he has ruined his career by his far-left musings -- to be kind -- and this is just another one of them," O'Reilly said of Moore.

"We can only hope," said his guest, Ian Tuttle of the National Review.

The progressive documentarian angered conservatives after calling snipers "cowards" on Twitter.

The Huffington Post reported that Moore later gave the film a positive review on his Facebook page, while also criticizing the movie's director, Clint Eastwood, saying he "gets Vietnam and Iraq confused in his storytelling."

O'Reilly later asked Tuttle, a William F. Buckley Jr. fellow at the Review, if he knew anything about "this Seth Rogen guy." The actor was also pilloried online after comparing American Sniper to a ficticious Nazi propaganda film depicted in Quentin Tarantino's movie Inglourious Basterds. Rogen later backtracked from the comments.

The Factor host expressed surprise at Rogen's statement, saying that Rogen "seemed fine" when they met at an event.

"I'd like him to come on this program and explain that," O'Reilly said. "If he doesn't, I think he's damaged his career immensely."
