Damian Lewis, Sophie Okonedo and the cast of The Goat, or Who Is Sylvia? celebrated last night following the opening of the play at Theatre Royal Haymarket.

Guests at the party also included Kate Fleetwood, Helen McCrory and Rupert Goold.

Edward Albee's play is about Martin (played by Lewis) who falls in love with a goat. In her four-star review for WhatsOnStage, Sarah Crompton said the conflict between Martin and his wife Stevie (played by Okokedo) "sometimes flows like a perfectly orchestrated aria".
