Having seen a little of the trailer of the interview I can see why it is Sony was threatened by trying to issue the film. This has to be the Hollywoods worst taste movie since perhaps D.W. Griffiths eulogy to the Klu Klux Clan since the Birth of a Nation, which it easily surprasses
While anybody here can say what they like there is limitations to what large established institutions like Sony, the New York Times, CBS News, 21st Century Fox can do and expect no repercussions. When was the last porno video you saw featuring Barack Obama and Queen Elizabeth issued by say Universal Studios. Which large movie house issued a fictional assassination attempt portrayed in a favorable light by the Klu Klux Klan?
North Korea is a nuclear totalitartian regime and a brutal regime. But they do have a leader and they do have missles with nuclear tipped weapons. Should a movie about a CIA planned assassination of North Korea's dictator be released the U.S. government would have to repeat serveral 1000 times about how this assassination was not U.S. government policy. It would be an embarassment to say the least to the U.S. to have to deny this was anything like official intentions. It would be great propaganda for the North Koreans. While Sony is an entertainment company it is understood certain things are not done without being cleared by governments who might be affected. On the other hand for at this stage the Obama administration to ban the movie outright would garnish the ire of the libertarians who believe in the right of "free speech". I personally don't object to government censorship if that censorship eliminates the risk otherwise significant of a nuclear war but others might not feel the same way.
What better method to get rid of the problem is to have some hackers either funded or associated directly with the CIA to reveal embarssing but largely harmless information from Sony. The government could blame the North Koreans and order investigations until the Storm blows over. Sony can be given a tax writeoff or other inducement quietly not to release the movie. As there is no information released linking the Koreans to the hacks, I will believe this theory for which there is opportunity, and motive for this to occur this way. If in fact, Sony did release this I will have to sell the stock of Sony short as this is the most idiotic storyline I can think of for Movie Studio to build a script about. On the other hand, if this is the work directly or indirectly of the CIA then I have to say that my respect for them goes up a notch. I cannot no longer assume that as an institution, they are largely bereft of intellgence.
