Sometimes linked with Hour of the Wolf (1968) and Shame (1968) as a third element of a trilogy set on Fårö island, Ingmar Bergman's The Passion of Anna is a characteristically intense working out of themes of grief and guilt, involving two couples whose lives intersect against a backdrop of mysterious instances of cruelty toward animals. I find it one of Bergman's more forgettable films, but it has strong admirers.
