Comedian Seth Rogen has responded to North Korea's comments about his upcoming movie with James Franco, The Interview, in which the pair are tasked with assassinating Kim Jong-Un.

The country's foreign ministry labelled the film a "wanton act of terror" and challenged the Obama Administration to ban it of face a "resolute and merciless response".

Seth Rogen – being Seth Rogen – responded on Twitter with the following:

Prior to North Korea's threat, an unofficial spokesman for the regime said: "A film about the assassination of a foreign leader mirrors what the US has done in Afghanistan, Iraq, Syria, and Ukraine.

"And let us not forget who killed [President John F.] Kennedy – Americans," the spokesman added. "In fact, President Obama should be careful in case the US military wants to kill him as well."

The Interview sees Franco and Rogen play a budding journalist and his producer who, after setting up an interview with Kim Jong-Un, are tasked by America's CIA with killing North Korea's supreme leader.

The film also stars Lizzy Caplan and Randall Park as Kim Jong-Un. It will be released (hopefully) on 29 October 2014.
