This movie is based on the book of the same name written by Colin Clark, who as a young man spent time as an assistant on the movie The Prince and the Show Girl starring Marilyn Monroe and Sir Laurence Olivier. He chronicles the friction between the two stars—Marilyn was insecure and dependent on pills, Sir Laurence was punctual and obsessive. As the production became more chaotic, Marilyn turns to Colin as a confidant and the two wind up spending a week palling around seeing the sights together. The movie is a gem and the acting is superb. Michelle Williams received an academy award nomination as best actress and it is easy to see why. She embodies Marilyn exuding the charisma and vulnerability of the late actress.
