Do we play to play?

Now for reals. So this is not the play but an interview done with Jude Law. He recently performed Hamlet on stage in London, about a year or so ago. The way he describes what he went through while playing Hamlet was very much like what Mr. Sexson was saying in class about how Hamlet was ( bad way of re-saying this) " he new the meanings behind everything." Jude says that he " somewhat became Hamlet while playing him", being able to see what it took to become "the madness with in the man". I believe that we all, in turn, play Hamlet at one time or another. Maybe not questioning whether or not we should live or die but questioning the cosmos and the way in which we live. Is it not true?
