Sigourney Weaver in The Tempest might be worth a punt... though the one I really want to see is The Merchant of Venice 1936 at Trafalgar Studios. Ann-Marie Duff is in The Little Foxes at the Young Vic, and Jodie Whittaker's in an update of The Duchess of Malfi called The Duchess. Guys and Dolls is still on at The Bridge. Importance of Being Earnest and Dr. Strangelove are coming to NT Live, if that affects your thinking.
