This play has a flexible cast. Not all scenes need to be performed. And actors can play multiple parts because no characters repeat from scene to scene. The smallest cast you could have by doing all the scripts would be three males and four females. But there are many as 49 speaking roles possible. Each scene can be performed as an individual one act as well.
