First Look: Kenneth Branagh as Laurence Olivier in MY WEEK WITH MARILYN | WhatCulture!: The film is based on the diary written by Monroe’s (Michelle Williams) assistant Colin Clark (Eddie Redmayne) during the production of the 1957 movie The Prince and the Showgirl. The new movie follows their friendship and Monroe’s turbulent relationship with director and co-star Laurence Olivier with incredibly fun supporting roles for Judi Dench (Dame Sybil Thorndike), Dougary Scott (as Arthur Miller), Julia Ormond (as Vivien Leigh) and Dominic Cooper (Arthur Miller). Emma Watson and Toby Jones also support.
