LOS ANGELES (AFP) - Sony Pictures Entertainment on Wednesday announced a special DVD and Blu-ray version of its controversial film The Interview with extra content that will poke fun at the idea of dating North Korean leader Kim Jong Un.

In a statement, Sony said the "Freedom Edition" of the Seth Rogen and James Franco caper - about a CIA plot to assassinate Kim - would be released on Feb 17.

It will include 90 minutes of bonus content, including 14 deleted scenes, seven minutes of bloopers and eight "featurettes".

One of the latter is cryptically described as "'Dating a Dictator' - An authoritative touch on a convincing dating profile video".

Sony did not respond to an e-mail request to elaborate.

The Interview was scheduled for a Christmas Day release before Sony became the target of the biggest cyber attack in US corporate history.

Threats made by hackers prompted Sony to initially cancel its theatrical release.

It eventually was screened in arthouse cinemas, and released on the Internet and via cable TV providers.

Washington has blamed North Korea for the hack on Sony, but Pyongyang has denied that claim - though it strongly condemned the film.

The Interview has since become Sony's best-grossing online film ever, making more than US$31 million (S$41 million) on the Internet and other small-screen formats.

Feb 17 is the day after the birthday of the late Kim Jong Il, father of Mr Kim Jong Un, which ranks as one of communist North Korea's most important public holidays.
