Emma Watson Pictures: Emma Watson attends the "My Week with Marilyn" UK movie premiere at Cineworld Haymarket on November 20, 2011 in London, England.

Colin Clark met Marilyn Monroe while working as a young assistant on Laurence Olivier's "The Prince and the Showgirl." When Marilyn experienced emotional difficulties during shooting, the 23-year-old third assistant director came to her aid and romance developed. But one week of honesty and fun was not enough to save the doomed star from self-destruction.

"My Week with Marilyn" opens in theaters on November 23.
