Who Will Make the Better Marilyn Monroe: Naomi Watts or Michelle Williams?

There is only one Marilyn Monroe, but now two actresses are set to embody the bombshell on screen. It was announced this week at the Cannes Film Festival that Naomi Watts, 41, will play Monroe in a biopic based on author Joyce Carol Oates's controversial, fictionalized memoir, 2000's Blonde. The movie, also called Blonde, is reportedly slated to start filming in January.

Meanwhile, 29-year-old Michelle Williams is in active negotiations to play Monroe in a film directed by Simon Curtis, which focuses on the late screen legend's time spent in England while filming 1957's The Prince and the Showgirl with Laurence Olivier.
