I'm currently in the process of designing the set for the Diary of Anne Frank, and my high school has decided that we would like to incorporate multimedia into the show (for when Anne's words are seen on the stage or we see soldiers marching in the streets, for those who know the show). My question is: what do I need to incorporate into the set for the multimedia to be projected on? Would any sort of wall that is already built into the set suffice, or would paint treatment and angles interfere with that? I would love to avoid an actual screen in the set - using a wall would be much better. If the walls of the set do not suffice, would incorporating a black wall work? I'd hate to have a random white wall on stage, though a black wall could easily disappear from view when not in use. Suggestions?
