"It has always been Sony's intention to have a national platform on which to release this film," said Michael Lynton, Chairman and CEO of Sony Entertainment. "With that in mind, we reached out to Google, Microsoft and other partners last Wednesday, December 17th, when it became clear our initial release plans were not possible. We are pleased we can now join with our partners to offer the film nation-wide today."
The studio made the announcement a week after it had announced that it would not release the film due to threats of a terrorist attack on theaters showing the comedy. But it reversed that stance on Tuesday.
"The Interview" stars Seth Rogen and James Franco as two bumbling American TV journalists tasked with assassinating North Korea's Kim Jong-un, The developments to make "The Interview" available come after Sony Pictures chief Michael Lynton said in a CNN interview last Friday that no video-on-demand providers were willing to release the movie. That apparently has changed after a groundswell of support in the U.S. for releasing "The Interview" -- with President Obama praising Sony for reversing course and deciding to authorize screenings on Christmas Day.
"We never stopped pursuing as wide a release as possible for 'The Interview,'" Lynton said. "It was essential for our studio to release this movie, especially given the assault upon our business and our employees by those who wanted to stop free speech. We chose the path of digital distribution first so as to reach as many people as possible on opening day, and we continue to seek other partners and platforms to further expand the release."
"I want to thank Google and Microsoft for helping make this a reality. This release represents our commitment to our filmmakers and free speech. While we couldn't have predicted the road this movie traveled to get to this moment, I'm proud our fight was not for nothing and that cyber criminals were not able to silence us."
Sony has been under siege since Nov. 24 when hackers struck with a massive attack.
"No doubt the issues we have confronted these last few weeks will not end with this release, but we are gratified to have stood together and confident in our future," Lynton said. "I want to thank everyone at Sony Pictures for their dedication and perseverance through what has been an extraordinary and difficult time."
