I was not the only person in the darkened theater to breathe an inward sigh of relief when Jude Law took the stage. His daughter had been born the night before, so there had been some uncertainty as to whether the star of Hamlet would indeed be playing Hamlet. He was, and the show went on at the Broadhurst Theater, which is hosting a limited run of this successful London production, to general applause and more than a few chuckles. Chuckles and Hamlet might not seem to go together, and please do not be led to think that director Michael Grandage is exploring the humorous side of Shakespeare’s tragedy.
