Hamlet was a role with which Gielgud was associated over the next decade and more. After the run at the Queen's finished he turned to another part for which he became well known, John Worthing in "The Importance of Being Earnest". Gielgud's biographer Jonathan Croall comments that the two roles illustrated two sides of the actor's personality: on the one hand the romantic and soulful Hamlet, and on the other the witty and superficial Worthing. The formidable Lady Bracknell was played by his aunt, Mabel Terry-Lewis. "The Times" observed, "Mr Gielgud and Miss Terry-Lewis together are brilliant ... they have the supreme grace of always allowing Wilde to speak in his own voice."
