Through a glass comprehensively

The Swedish Film Institute offered a sneak preview Thursday of a new exhibit focusing on filmmaker Ingmar Bergman’s first forays into cinema.

The exhibit, which was shown to journalists and film devotees in Stockholm, will go on a European tour later this month. Titled “Before Ingmar Became Bergman,” it is composed of personal letters, behind-the-scenes film footage and archived work from when he was in his early 20s and still a nascent filmmaker. The writer and director, now 85, donated the material to the institute last year.
