The animal costume worn by Winfried is the Kukeri, a common animal totem in Bulgaria that is believed to scare away evil spirits. It was made from the real hair of long-haired goats and according to actor Peter Simonischek was extremely hot and heavy and smelled like a goat stable. With the exception of the scene when Winfried has the head removed, it was worn by a stuntman.
At the Bucharest office of Ines' company, an inscription on the wall says: "Don't judge each day by the harvest you reap but by the seeds you plant."
Winfried Conradi is loosely based on Maren Ade's father who actually likes to put in fake teeth to joke with people.
120 hours of footage were shot during 56 shooting days.
According to writer/director Maren Ade one inspiration for Winfried's special brand of irritating humor was late comedian Andy Kaufman.
