Continuity mistake: In the first club session, where Winkelmann presides, a pair of glasses appears in the pocket of his jacket right before he puts them on. (00:10:55)
Continuity mistake: In the scene where Winkelmann and Mrs. Tietze try to make the Melzers change their sofa upholstering to something less depressing, they step out to have a private talk and end up in a muddy flower bed. When they walk back in they don't leave any marks on the terrace but heavy mud prints on the living room floor, although Winkelmann's shoes look spick-and-span after he sits down. (00:25:55)
Continuity mistake: When Winkelmann, Tietze, and the Italian agent drive off there's a wild load of furniture on the rooftop. When they stop over at the latter's brother-in-law's estate the furniture arrangement has changed completely. (00:42:40)
Continuity mistake: When Winkelmann enters his shop near the beginning of the movie there is something like a security sticker on the right side, but when the camera cuts to inside the sticker is gone. (00:03:20)
