A few months ago it was reported that Scarlett Johansson was leading a list of actress under consideration to play Marilyn Monroe in director Simon Curtis' biopic, My Week with Marilyn. Kate Hudson, Amy Adams and Michelle Williams (Brokeback Mountain) were also mentioned as possible contenders for the role.

Production Weekly has now learned that Johansson is out of the running and that its Williams who is in-talks with Curtis to top line the movie, set to begin lensing in June, 2010.

My Week will be based on the diary of Colin Clark, an employee of Laurence Olivier, who looked after Monroe when she came to London to film Olivier's "The Prince and the Showgirl" in 1957. Although Colin was technically considered the third assistant director, his unofficial role was to keep Monroe out of Olivier's way.

Clark published excerpts of his diary a year later, but left out the details of one week. Those unreleased chapters form the basis of the movie.

Frankly, it's probably one of the toughest roles to cast. Monroe's body movements, mannerisms and vocal inflections are legendary. Difficult to master, impersonators who have done so typically haven't looked that much like the late actress. Alternatively, those who look somewhat like Monroe have more often than not had a tough time duplicating her essence. It will be interesting to see how this all plays out...and if Curtis decides to employ today's current state-of-the art CG to give his leading lady a little extra "authenticity," or if he simply allows her to develop a close individual interpretation of the Monroe essence, sans special effects.
