As a footnote to the above, I would like to say that I am getting very tired of literary authorities, on both the stage and the screen, who advise young writers to deal only with those subjects that happen to be familiar to them personally. It is quite true that this theory probably produced A Tree Grows in Brooklyn, but the chances are it would have ruled out Hamlet.
