The idea of David Mamet adapting British playwright Terence Rattigan’s play, based upon a true incident, might seem strange. But there is much of Mamet – his signature style and his regular concerns – to be found amidst the costumes and cadence of the 1912 London setting. Young Ronnie Winslow is sent home from naval college in disgrace, accused of stealing. Determined to clear the family name, the Winslows hire star barrister Sir Robert Morton (Northam), intent on winning the case, no matter what the cost. Nigel Hawthorne as the head of the household leads with a sterling performance.
