From the origins of cinema, the relationship between theater and the moving image has been persistent. It has also been problematic in several ways. Theatre seemed a particularly suitable medium to provide film with plots, as well as actors and a sense of staging. The two media proximity has caused many misunderstandings and not a few headaches to writers, producers and film directors. The aim of this article is to trace different options for film adaptations of theatrical texts and also to understand the problems posed in several films by Orson Welles, Roman Polanski, Louis Malle, Peter Brook, and Ingmar Bergman.
