In 1956, fresh from Oxford, 23-year-old Colin Clark worked as a humble 'gofer' on the set of The Prince and the Showgirl. The film united Britain's leading actor, Laurence Olivier, with Hollywood's most glamorous sex symbol, Marilyn Monroe - and clashes between them entered film legend. For one glorious week, the world's biggest film star sought comfort in the arms of the set's most junior employee. This is the frank, fresh and comic story of how Clark came to share Monroe's confidences - and her bed.
