Madness Rules
1947 film by Leopold Lindtberg

Madness Rules (German: Matto regiert) is a 1946 Swiss crime film directed by Leopold Lindtberg and based on a novel by Friedrich Glauser. It is one of Lindtberg’s Wachtmeister Studer films and was later screened at the Zurich Film Festival.
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own experience of psychiatric institutions, and the film presents both a crime story and a conflict between modern and outdated psychiatric methods.
Synopsis

Why this record matters
“Madness Rules” is worth following because a concise public description often conceals a longer documentary argument. Here, Madness, Rules and film provides the most credible route into that argument.
Object files, edition statements, performance records and contemporary criticism preserve different stages of the work’s history. The source revision retrieved here is dated Apr 6, 2026. The linked authority identifier is Q3307609. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1946 and 1939.
Rights, attribution and provenance may remain disputed even when a general reference summary presents a stable account. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
