Bergman made this film in Germany, while in exile from Sweden for tax-related reasons. It's a dark and disturbing psychological portrait of a man, Peter, who murders a prostitute in the opening scene. The film moves back and forth in time, using title cards to establish the setting in time, trying to explain Peter's troubles. It's reminiscent of Scenes from a Marriage, as Peter has problems relating to his wife, Katarina. A few weeks before the murder, he started having fantasies and dreams about murdering her. The prologue, depicting the murder (or, more precisely, the moments before the murder) and the epilogue (Peter in prison) are filmed in color, but everything else is in black and white. The composition is generally not showy, but there is an amazingly filmed dream sequence, the film's centerpiece. The script is generally brilliant, very observant. The only thing I felt was a little underdeveloped was the homosexual character, Tim, and Peter's supposed latent homosexuality, which the psychoanalyst character describes near the end. I wasn't quite sure what to make of that material. 9/10.
