Malpertuis is a labyrinth where characters issued from the Greek mythology are made prisoners by Cassavius. He manages to keep them (as well as his nephew and niece) as prisoners even after his death, through a binding testament. As the nephew unravels the mystery, we find out he cannot escape the house because Malpertuis is far more significant than we were led to believe. Written by

Director Harry Kümel
was a passionate admirer of Orson Welles
and had him in mind for the role of Cassavius right from the beginning. According to him, it was pretty easy to convince Welles to take the part, once they assured to pay him the salary he asked for. Looking forward to meet and direct his idol, Kümel was pretty nervous when walking onto the set - just to find out that Welles was in a bad mood and drunk. He later stated in interviews that he personally got along well with Welles during the rest of the shoot but the majority of the crew didn't and tried to get out the grumbling Welles' way most of the time.
