The whole movie was shot in 3 days.
The original stage production opened at the Spinoza Theater in Budapest on October 20, 2018. It was also directed by András Korcsmáros and featured the same cast. The credited writer for the play was Ray McDonagh but actually, it was a pseudonym for Korcsmaros. He didn't want his name to appear three times on the poster, so he chose this name as an homage to Martin McDonagh, whose movies and plays inspired him to write this story.
