H is a production that arrives in London after months on the road, and must be taken as the considered work of the director ( John Gielgud himself) and his cast. They have had time enough to correct minor faults, of which there must have been few from the start. The presentation has a smooth majesty within the simple frame that Michael Ayrton and John Hinton have devised. William Walton’s music is composed for the occasion but played from recordings, and many of the cast double their parts as a wartime measure. All this detail has been well thought out and ingeniously woven into the pattern. Such a Macbeth could never fail for lack of pains.
