Noël Coward wrote many excellent plays – as well as a fair amount of less-than-excellent ones – but few are revived as often as his 1939 masterpiece Present Laughter. It isn’t at all hard to see why. Coward created the egotistical and spoilt character of a forty-something leading man, Garry Essendine, as a self-portrait, to wittily lacerating effect, and in the process created one of the great roles of twentieth-century theatre. Countless leading men have tackled the part, some with enormous distinction and others with less flair. Now Matthew Warchus, the Old Vic’s artistic director, is staging it, complete with man-of-the-moment Andrew Scott as Essendine.
