Hacktivist group Anonymous have promised to leak Seth Rogen and James Franco comedy The Interview after Sony decided to pull its release amid an enormous, public cyber-attack believed to have been perpetrated by North Korea.

In a series of tweets from an account now suspended, the group said: "Operation RIP North Korea, engaged. #OpRIPNK.

"We're not with either side, we just want to watch the movie too... and soon you too will be joining us. Sorry, @SonyPictures.

Sony Pictures announced last week that the controversial film - which depicts the assassination of North Korean leader Kim Jong-un - would be pulled from its planned US release on Christmas Day after threats were levelled at theatres showing the movie and cinema chains subsequently opted not to show the feature.

This all came after a cyber-attack which resulted in numerous leaked emails and salary details that have damaged the company and in particular its co-chairman Amy Pascal.

Following Sony's decision the FBI blamed the attack on North Korea, saying it was "intended to inflict significant harm on a US business and suppress the right of American citizens to express themselves."

President Barrack Obama then criticised Sony for their decision, saying they had "made a mistake" in caving to the demands of the cyber-terrorists.

Sony Pictures then said they were looking into alternate means of releasing the film, despite originally saying there were no plans to release the film digitally or on DVD and Blu Ray.

New reports claim Sony plans to distribute the film for free via streaming service Crackle.
