London, Dec 27: North Korea has condemned US President Barack Obama over the release of the film "The Interview", which is about a fictional plot to kill its leader Kim Jong-un.
The country's National Defence Commission (NDC) also accused the US of shutting down the country's internet - and used a racial slur to describe the "reckless" Mr Obama.
Sony Pictures had originally pulled the title after a cyber-attack and threats.
But the company later reconsidered, releasing the comedy on Christmas Day.
A number of critics - including the US president - had warned that freedom of expression was under threat if the movie was shelved.
The controversial film was shown in some US cinemas and online, with several hundred independent theatres coming forward and offering to show the film. However, larger cinemas decided not screen it.
Kim Jong-un's potential difficulty is that The Interview - which casts the North Korean leader as a malign, vain buffoon - has been widely reviewed as funny and astute, the BBC's Stephen Evans in Seoul reports.
If activists start smuggling it into North Korea on USB sticks, as they already do with other films, it might prove quite powerful, our correspondent adds.
In a statement on Saturday, an NDC spokesman denounced the US for screening the "dishonest and reactionary movie hurting the dignity of the supreme leadership of the DPRK [North Korea] and agitating terrorism".
The statement said, "President Obama is the chief culprit who forced the Sony Pictures Entertainment to indiscriminately distribute the movie", blackmailing cinemas in the US.
It added: "Obama always goes reckless in words and deeds like a monkey in a tropical forest."
The NDC also accused also Washington of "groundlessly linking the unheard of hacking at the Sony Pictures Entertainment to the DPRK".
Sony Pictures had initially pulled the film after suffering an unprecedented hacking attack at the hands of a group calling itself the Guardians of Peace.
The hackers also threatened to carry out a terrorist attack on cinemas showed the film on its scheduled release date of Christmas Day.
