When San Francisco State University’s theater arts department commissioned Mark Jackson to adapt and direct a production of “Romeo and Juliet,” he came up with the unusual idea of creating a version of the tragedy for 14 actors, all cast in the role of Juliet. But because of budget cuts at the university, less money is available for items that affect the look of a production, like sets, lights and costumes. So to save on wardrobe, Mr. Jackson has had to readjust his core creative concept: now he has just eight actors for his new show, “Juliet.”
