Brianne, the protagonist of Eric Bogosian’s new play 1+1, is an L.A. waitress who wants to become an actress. One of her customers, a travel photographer, promises to make her a star. The plot may sound cliché but it quickly turns dark. Manipulated into performing Internet porn, Brianne’s only potential help is her boss at the restaurant, a man with a crush on her. “Though the piece seems to be about internet porn and one victim in particular, what I wanted to get at was a deeper examination of responsibility when two people share blame over bad actions,” Bogosian has said. “What I want is for the audience to ponder this particular set of circumstances through the eyes of the three characters.” Jo Bonney directs. —Jensen Davis
