North Korea must be pretty bad at self-deprecation, because the country has just submitted an official complaint to the UN over the forthcoming release of James Franco and Seth Rogen's comedy, The Interview.

In the film, Franco and Rogen play two undercover journalists who are recruited by the CIA to asassinate North Korean leader Kim Jong-Un. Two weeks ago, a spokesperson described the film as a "blatant act of terrorism and war" to a state news agency. Now the country has taken the issue to the United Nations, with its UN ambassador Ja Song Nam writing a letter of complaint to UN Secretary-General Ban Ki-Moon. 

The letter does not mention the film's name, but refers to a plot that involves "insulting and assassinating the supreme leadership".

"The United States authorities should take immediate and appropriate actions to ban the production and distribution of the aforementioned film; otherwise, it will be fully responsible for encouraging and sponsoring terrorism," Ja wrote. 

Seth Rogen has addressed the uproar on Twitter, saying, "People don't usually wanna kill me for one of my movies until after they've paid 12 bucks for it." Quite. Whatever happens, it's great publicity for the film, due out in October.
