Seth Rogen's second shot in his "act of war" against North Korea was even better than the first.

On Wednesday, a spokesman for North Korea's Foreign Ministry called Rogen's upcoming film "The Interview" an "act of war" against his country and demanded the United States ban it.

Rogen responded on Twitter: "People don't usually wanna kill me for one of my movies until after they've paid 12 bucks for it. Hiyooooo!"

Oh, we can't wait for North Korea's response to that one.

"The Interview" is about two talk show hosts, played by Rogen and James Franco, interviewing North Korean leader Kim Jong-un and then being enlisted by the CIA to assassinate the leader. North Korean state media reported on Wednesday that the U.S. government would face "stern" and "merciless" retaliation if it failed to stop the movie's release in October.

So far, U.S. government officials have been surprisingly quiet about the matter. Could it be that no one is taking North Korea seriously?

And why isn't North Korea going after Canada? After all, that is Rogen's native country.

North Korea's unofficial spokesman Kim Myong-chol clearly has it in for Americans. He was quoted Wednesday as saying, "A film about the assassination of a foreign leader mirrors what the U.S. has done in Afghanistan, Iraq, Syria and Ukraine. And let us not forget who killed (John F.) Kennedy -- Americans. In fact, President Obama should be careful in case the U.S. military wants to kill him as well."
