This better not be an early April Fool’s Day joke.  We posted back on 21 July 2015 that the release date for Poland was 4 March 2016.  That is the date that is also listed at IMDb, but I noticed today that both Filmweb Poland and Stopklatka Poland are showing 1 April 2016 at the Polish release date.  Time will tell obviously which date is correct.  There’s nothing on Best Film site as yet, but as usual I will keep you posted.
