In 1956, Clark (brother of Tory politician and diarist Alan) spent a summer, aged 23 and straight out of Oxford, working on the set of The Prince and the Showgirl. The film united Marilyn Monroe with Sir Laurence Olivier and 40 years later Clark's diary about the experience became a bestselling book. But one week was missing. My Week with Marilyn tells the tale of those omitted days, during which Marilyn asked Colin, who died in 2002, to help her escape the stress of stardom and of balancing her honeymoon with Arthur Miller with the demanding filming schedule. This new edition of his acclaimed memoirs brings both stories together in one volume, with an introduction by Simon Curtis, director of a new film based on the book, and an interview with the screenwriter Adrian Hodges. While the world could probably do without yet another book about Marilyn, Clark is both a sharp and affectionate diarist. Having landed the job through family connections, he did everything in his power to make himself indispensible and his book has an entertaining narrative bounce.
