According to the source that Pol3 provided, it's a tiny movie theater in Charlottenburg that cancelled the show due to security concerns. The movie will still be shown in other cities such as "Hamburg, München, Düsseldorf and Köln"
Please notice that security concerns were given in second place, in first palce was its controversial nature: der Film sei zu kontrovers.
That's not true. Security concerns were mentioned right above and below the headline.
So it's just a pretext for the PC dictatorship to again rear its ugly head, is it?
Nonsense. Maybe the venue is owned by Poles who don't like the movie? :)
