After its 2015 Broadway premiere Simon Stephens’ new two-hander HEISENBERG:THE UNCERTAINTY PRINCIPLE has arrived in the West End at the Wyndham’s Theatre. Directed by Marianne Elliot, it is the debut show for her new company Elliot and Harper and stars Anne-Marie Duff and Kenneth Cranham. It’s an 80 minute study of a mismatched couple, riffing on life, love and everything in between. Anne-Marie is Georgie, an American school receptionist in her forties, who jokes she’s an assassin and Kenneth plays Alex, a seventy year old butcher who’s used to being self contained. Both signed my drawing after last Saturday’s evening performance.
