A group of hackers claiming to be responsible for the massive computer breach of Sony Pictures Entertainment has demanded that the movie studio company cancel the release of the upcoming comedy "The Interview." The hackers feel that the Seth Rogen and James Franco flick is a "movie of terrorism" because it depicts an assassination plot against North Korea's leader.

NBC News reports a letter posted to a code-sharing website Monday said Sony should "stop immediately showing the movie of terrorism which can break the regional peace and cause the War!" This message was signed by a group named the "GOP," an acronym for "Guardians of Peace," who say they are responsible for the crippling digital break-in at Sony, which began Nov. 24.

The GOP letter posted on Monday also included links to several gigabytes of downloadable data purported to have been stolen from Sony.

The guardians said, however, that they were not involved in a threatening email sent out to Sony staff last Friday.

Some security investigators suggested that there were links to North Korea in the Sony hacking, but a diplomat denied any involvement from his country.

North Korean officials in Pyongyang have already denounced "The Interview" as "undisguised sponsoring of terrorism, as well as an act of war," in a letter written to U.N. Secretary-General Ban Ki-moon, NBC News reports.

The movie is scheduled for release on Christmas Day, and Sony hasn't commented on whether these events will have any effect on the film's distribution.

In "The Interview," Franco plays a famous entertainment television interviewer who is invited to visit the Asian country and meet the dictator. However, when the CIA learns of this opportunity into the heavily guarded North Korean leadership, they ask Franco and his business associate and buddy, played by Rogen, to "take out" the country's leader. The film's comedic elements arise when the dim-witted team blunder every covert mission they are given.
