Rollelisten er lang, jvnf. Shepherds bemærkninger i rollehæftet: There are several leading roles and a great many characters, many more than is usual in a contemporary play, where economic necessity often limits the writer to a handful of characters and one set. This means that most of the actors will have to transform themselves into a variety of parts. If the story is to unfold as it should, these transformations will have to be convincing.
