Many celebrities are outraged at Sony’s decision to cancel The Interview, and now George R.R. Martin is taking action.

If anyone knows anything about bravery and cowardice, it’s A Song of Ice and Fire author George R.R. Martin. And when he publicly denounces you a coward, in capital letters, you may as well pack it in and join the Night’s Watch (for a second chance of glory, of course).

Earlier this week it was revealed that the Sony hackers were threatening movie theaters that were planning to show Seth Rogen’s North Korea comedy The Interview, and in response, Sony announced their decision to completely cancel the movie, potentially never releasing it.

Note that the U.S. government has found no indication that there would be an actual physical threat.

“I mean, really? REALLY?? These gigantic corporations, most of which could buy North Korea with pocket change, are declining to show a film because Kim Jong-Un objects to being mocked?” Martin scolds on his blog, in a post titled “Corporate Cowardice.”

Following Sony’s decision, Fox announced that they would not be distributing the planned Gore Verbinski/Steve Carell adaptation of the graphic novel Pyongyang, which was set to explore the darker sides of the North Korean dictatorship (as in: not a comedy).

Alamo Drafthouse was planning to screen Team America: World Police in place of The Interview, but Paramount nixed that idea, too.

“The level of corporate cowardice here astonishes me,” Martin continues. “It’s a good thing these guys weren’t around when Charlie Chaplin made The Great Dictator. If Kim Jong-Un scares them, Adolf Hitler would have had them shitting in their smallclothes.”

Martin explains that it is not The Interview itself he’s worried about not getting to see; what upsets him is that Hollywood would bow to these types of threats. “It astonishes me that a major Hollywood film could be killed before release by threats from a foreign power and anonymous hackers,” he says.

Martin declares that while the big corporations have bowed out, “there are thousands of small independent theatres across the country, like my own, that would gladly screen The Interview, regardless of the threats from North Korea.”

In the comments, he also shuts down the argument that Sony should not be overlooking potentially serious threats: “There’s a huge middle ground between ‘ignoring the threat’ and ‘giving in completely to the terrorist,'” he says.

He expresses his regret that Sony has chosen to cancel the film completely, and hopes that he’ll get to screen it in his Santa Fe-based independent cinema Jean Cocteau.

“Come to Santa Fe, Seth, we’ll show your film for you,” Martin finishes. His Livejournal mood status is set to “pissed off.”
