After North Korea, through a complaint letter to the United Nations, expressed their anger against the upcoming comedy, The Interview, Seth Rogen only brushed off the reclusive country's threats.

In the June 27 letter to the UN, a North Korean representative, Ja Song Nam, accused the United States for "sponsoring terrorism as well as an act of war" by allowing the movie to be promoted and released.

They went on to demand, “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."

In previous reports, Seth Rogen merely addressed the controversy with cheeky replies via Twitter. He earlier tweeted, “People don't usually wanna kill me for one of my movies until after they've paid 12 bucks for it. Hiyooooo!!!"

In an interview with The Canadian Press, however, the comedian and director expressed his surprise at the whole incident.

“It's kind of shocking," The Interview's Seth Rogen said, “I can't even believe that they even know it exists at this point. We thought it would happen once it came out. I wonder what they'll say when they see it."

The secretive country had even threatened a "resolute and merciless" response to the US should the film be allowed to show in cinemas, but the 'This Is The End' star didn't seem to be affected by it.

"I think as far as getting the movie out there, it's been helpful," the TV and film star reportedly said while laughing.

Evan Goldberg, Rogen's friend and co-director, also expressed his nonchalance over the matter.

"They talk big over there," Goldberg dismissed the North Korean complaint. "They say crazy stuff all the time."

'The Interview's' Seth Rogen earlier expressed his hopes via Twitter that the North Korean President Kim Jong Un will watch the film and like it.

Set to hit US theaters in October later this year, 'The Interview' features Rogen and James Franco as journalists who get recruited by the CIA to assassinate the North Korean leader.
