From the Life of the Marionettes

Produced and directed for German television, Ingmar Bergman's From the Life of the Marionettes starts out in color and switches almost immediately to black-and-white. This cinematic self-indulgence is ideally suited to the subject matter: the horrible consequences of a rapidly disintegrating marriage. The husband, Peter Egerman (Robert Atzorn) is unable to articulate his frustration through normal channels. Warped by his repression, Egerman ends up raping and murdering a prostitute. This outrage occurs at the very beginning of the film; the rest of the footage is devoted to a semi-documentary study of the failed marriage, the police investigation, and the husband's twisted psyche.
