Background
Madness Rules is based on Friedrich Glauser’s novel Matto regiert. Heinrich Gretler plays Wachtmeister Hermann Studer. He had previously played the character in Leopold Lindtberg’s 1939 film Constable Studer, which was adapted from a novel by Glauser.
Glauser drew on his own experience of psychiatric institutions, and the film presents both a crime story and a conflict between modern and outdated psychiatric methods.
