Dialectical Montage with Roots in Epic Theatre

Dialectical Montage: the juxtaposing of specific scenes of a movie to determine a relationship between the two (or more).
Epic Theatre: Theatre which uses the "V-Effect" to break the audience's emotional bond with the play and alienates them from what's happening on stage.

These two concepts used together can be a very interesting combination. It is known that Bertolt Brecht liked to use technology in his plays, and in some of them he added a large screen in the background to show video footage. I was always curious as to what exactly he (or the directors who are adapting the play) chose to show on those screens as the play went on. I was able to find this out recently.

Recently at York Private School there was a production of Brecht's The Resistable Rise of Arturo Ui. As I wasn't able to make it out to actually see the play when it was on stage, my friend, who went to that school, was able to see it. He told me they showed clips of Stalinist Regimes and Communist gatherings along with landscapes and such. As I wasn't able to see it, I am not sure, but it seems to me that the director decided to use dialectical montage to emphasize some specific points throughout the play.
