North Korea has condemned US President Barack Obama over therelease of the film The Interview, 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 is available online, with several hundred independent theatres coming forward and offering to screen it.
However, larger cinemas decided not to show the film.
'Righteous deed' In a statement issued 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".
President Obama, the statement said, "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".
