Literature: Film adaptations of plays & operas

Plays can be read, operas too, in the form of a libretto. In both cases, a high-quality literary reading can be enjoyed. But of course both forms belong first and foremost on the stage, performed live in front of an audience, reinterpreted again and again, always excitingly different in dramaturgy and staging. The cinema has also adapted a number of plays for the big screen, even operas, but comparatively few of them. A "theatre film" or an "opera film" merely films a stage performance, whereas a theatre or opera film adaptation seeks its own cinematic ways to open up a work.
