The London Times sent critic Kate Maltby, a freelance contributor to the paper, to review it. Her verdict , posted online within hours of the curtain coming down on the first preview, gave the show a two-star review, declaring, "This is Hamlet for kids raised on 'Moulin Rouge'." The Daily Mail also broke the customary embargo, but sent a columnist Jan Moir, not a theatre critic (even though she awarded it a five-star rating).
The last high-profile breach of this type occurred in 2011, when critics began publishing reviews for the Broadway musical Spider-Man Turn Off the Dark after the troubled production pushed back its opening night and continued to languish in previews.
Cumberbatch is joined by a cast that also features Ciarán Hinds as Claudius, Jim Norton as Polonius, Leo Bill as Horatio, Sian Brooke as Ophelia, Anastasia Hille as Gertrude and Kobna Holdbrook-Smith as Laertes.
The production is directed by Lyndsey Turner, with sets by Es Devlin, costumes by Katrina Lindsay, video by Luke Halls, lighting by Jane Cox, music by Jon Hopkins, sound by Chris Shutt and movement by Sidi Larbi Cherkaoui.
