The rest of Deborah Warner's production is considerably more grown up and impressive. Though Shaw's costume is a bit too suggestive of a Comme des Garcons outfit, and the set of an expensive minimalist restaurant, on the whole Hildegard Bechtler's design is a model of chaste elegance. The long, narrow stage forms the lists for a series of rhetorical and physical combats, ending with the murder of the captive Richard, who runs wildly to the end of the rope that tethers him before being struck down.
Looking like a Holbein nobleman, Graham Crowden, as John of Gaunt, personifies the grandeur of a dying England, the "scept'red-isle" speech breathing all the regret and tenderness of a dying man. His scene with the Duchess of Gloucester is another picturesque and piercing moment, Paola Dionisotti's shrivelled monkey of a duchess tottering on two sticks with a vindictiveness great as her grief.
And, in this play about the triumph of a new order, Michael Bryant ironically turns in the other weighty performance, as the Duke of York - his "uncle me no uncle" has, in four words, more authority than all of David Threlfall's delicate portrayal of the usurper Bolingbroke.
Though Richard II was an ineffectual king, he was a king, and was a man. If an actress can project masculinity (and some are more capable of doing so than some actors) there is nothing against her taking up the sceptre and orb. Judging by this outing, though, Shaw doesn't have enough maleness to play Peter Pan.
