Mysteries of a Barbershop is a comic, slapstick German film of 33 minutes, created by Bertolt Brecht, directed by Erich Engel, and starring the Munich cabaret clown Karl Valentin and leading stage actor Erwin Faber. Brecht reportedly did not write a complete shooting script, but rather produced "notes" and "parts of a manuscript" for this short, silent film and intended the actors to improvise the action. Although the film was not considered a success by any of its creative team, and consequently was never released as a profit making film to the public, it has been recognized and acknowledged—since its re-discovery in a Moscow archive in the 1970s—as a considerably important German film.
