Judi Dench as Titania, Queen of the Faeries, in Peter Hall's latest Midsummer Night's Dream, currently on in London.
From Matt Wolf's NYT review:
Ah, how casting changes the character.I can report that I haven’t laughed so delightedly in ages as I did at the moment at which our heroine’s sexually reinvigorated fairy queen responds to a love-struck whinny from her adored Bottom (Oliver Chris), the weaver who has been transformed by the mischief-making Puck into an ass. Titania’s reaction? To let loose with an anticipatory neigh all her own, before she and her donkey-headed boy toy scamper off into the intermission to have — well, who can say precisely what sort of fun?
