The North Korean Foreign Ministry called on the organizers of the Berlinale to stop any showing of The Interview.
A spokesman accused the US of showing the film "behind a smokescreen in one of its vassal states, taking part in an international film festival".
Those who collaborate in "wounding the sovereignty and dignity of the People's Republic will not escape a merciless punishment", they threatened.
But there are in fact no plans to screen The Interview at the festival.
That's fairly embarrassing for the Pyongyang regime, which accused Germany of joining in with "hostile actions of the USA against North Korea".
North Korea appears to have been confused by the fact that the movie will appear in German cinema schedules from February 5th, the same day as the start of the Berlinale.
A film with the same name shown at the Berlinale several years ago does appear in Google results, but has nothing to do with North Korea.
US authorities have accused North Korea of being behind the hackers who carried out a massive and successful attack against Sony Pictures, the studio behind the movie, and have since strengthened economic sanctions.
Threats of terrorist attacks against cinemas didn't stop the studio from releasing the film in theatres and online.
