His name is known today mainly in connection with a legal case from 1950, whose background Lüth's boycott against the film Immortal Beloved, based on the novelAquis submersus by Theodor Storm. In 1951, Veit Harlan sued for an injunction against Lüth for publicly calling for a boycott of Unsterbliche Geliebte.
