Scarlett Johansson (pictured) is being lined up to play Marilyn Monroe.
The 24-year-old blonde beauty is reportedly at the top of a list of actresses being considered by director Simon Curtis and producer David Parfitt for new film My Week With Marilyn.
Kate Hudson, Amy Adams and Michelle Williams have also been mentioned as possible stars of the film, according to newspaper columnist Baz Bamigboye.
The movie will be based on the diary of Colin Clark, an employee of Laurence Olivier, who looked after the blonde bombshell when she came to London to film Olivier's The Prince and the Showgirl in 1957.
In the diary, Clark talks about showing Marilyn around Queen Elizabeth's private apartments at Windsor Castle and other "behind-the-scenes" trips.
Clark published excerpts of his diary in 1958, but left the details of one week out. These chapters weren't released until he died in 2002, and will form the basis of the movie.
Parfitt explained: "Once everyone else was dead, Clark had arranged for the missing week to be issued."
British film writer Adrian Hodges has adapted the papers into a script.
