“The first summer was pure happiness.” When “Liv & Ingmar” first meet, the Norwegian actress is 25 years old and the Swedish director is 46. They fall in love while shooting “Persona” in 1965. Liv, pregnant with Ingmar Bergmann's child, leaves her husband. She and Ingmar move to the Swedish island of Farö, where she soon experiences their life in strict togetherness as a prison ... Film excerpts and behind-the-scenes footage of “Hour of the Wolf” are reminiscent of the early days of an artists' relationship that was never entirely uncomplicated. Throughout individual chapters with titles such as “Love”, “Loneliness”, “Anger”, Liv Ullmann reflects on how passion grew into mutual respect and friendship, which enabled them to make a dozen films together, the last of which was “Saraband” in 2003. Quotes from both respective memoirs and from Ingmar's private letters to Liv unveil a relationship that the mutual work mirrors in all its light and dark facets.
