Bowing to the anonymous hackers who infiltrated Sony and threatened to blow up theaters, the five largest cinema chains in the United States have decided to pull The Interview.

—

Update 4 (Thursday, December 18, 9:45 a.m. eastern): Sony has announced that the film has been pulled from all theaters worldwide.

—

Update 3 (7:45 p.m. eastern): Sony may be set on never releasing The Interview in any form. According to a statement from Sony obtained by Deadline, the studio “has no further release plans for the film.” This would include a potential release online or OnDemand, like another trade publication suggested may happen earlier tonight.

Update 2 (6:15 p.m. eastern): The United States now believes that North Korea is behind the attack, reports NBC News. While the attack didn’t occur from within North Korea, the U.S. believes it was on North Korea’s orders.

Update (5:00 p.m. eastern): Sony has decided to pull The Interview from all theaters “in light of the decision by the majority of our exhibitors not to show the film.”

It’s too early to know what Sony will do with the movie now, but there’s the possibility they will release it as an On Demand feature or somehow distribute it online.

AMC, Regal, Cinemark, and Cineplex jointly announced Wednesday afternoon that the controversial Seth Rogen and James Franco film would not be played in their theaters. The fifth chain, Carmike, had announced their decision to pull the movie last night.

Regal issued a statement on its own, saying that their decision was made due to “the wavering support of the film […] by Sony Pictures, as well as the ambiguous nature of any real or perceived security threats.”

The theater noted that they are going to “delay” the opening but did not set a new date.

Their decision comes after “GOP,” the hacker group responsible for infiltrating Sony’s systems, promised yesterday that they would organize 9/11-style attacks on theaters that run The Interview on Christmas day.

The five aforementioned chains join Southern and Arclight theaters in pulling out of running the film.

North Korea is widely believed to be behind the hacks and threats, and the FBI says that the threats are not credible.

With most theaters in the United States now out of The Interview, the attention turns back to Sony. Will they pull the film from all theaters? Will they release the film online?

The decision to pull The Interview, due in theaters on Christmas Day, is very worrying. By giving in to the hacker group’s demands, Sony and theater chains are telling people that if they speak loudly enough, they too can pull films they don’t want in theaters. All you need to do is anonymously hack a studio and threaten to blow up movie theaters.

It’s a bad day for cinema in America.
