Some of Bergman's films have also been adapted as theater, most notably, if
I remember correctly, "Scenes from a Marriage." Liv Ullmann's
autobiography might have more information. Also, last night on TV was a
television presentation of a radio adaptation (far a live audience it
looked like) of "Its a Wonderful Life," a kind of stage presentation.
