"Our love affair was destructive and from the beginning carried all the misfortune imaginable in its baggage," explains Ingmar Bergman of his stormy relationship with Gun Hagberg, in his memoirs. The Magic LanternThe director met the journalist and future translator when they were both still married, he to his third wife, Ellen. The adulterous affair with Gun led to a new marriage, a son, and a subsequent divorce. It ended up inspiring two series. The first, Secrets of a marriage (1974), the Swedish television production we saw here in its film version. It's a piece that has left its mark like few other dramas about marital crises. The other creation based on that story is Unfaithful, the series that Filmin has just released, directed by Tomas Alfredson, which takes as its starting point another script by Bergman that had already led to a film of the same name by Liv Ullmann.
