Michelle Williams has been asked to portray one of film’s biggest stars.

The Oscar nominee has been lined up to play tragic screen icon vMarilyn Monroe in movie My Week With Marilyn, a feature that will focus on the making of her 1957 film The Prince And The Showgirl with Laurence Olivier.

Although Michelle has been offered the part by director Simon Curtis and producer David Parfitt, the 29-year-old beauty has asked for some time decide whether or not the part is right for her. Simon is due to meet with her in 10 days to receive her decision. If she accepts, Michelle will start filming in London in June.

The storyline - which was written by Adrian Hodges and is backed by BBC Films - is based on a diary written by Colin Clark. Clark worked for Laurence Olivier when he directed and co-starred in Showgirl. Although Colin was technically considered the third assistant director, his unofficial role was to keep Marilyn out of Laurence’s way.

The diary has already been published but details of one specific week were left out. This missing time frame will become the basis of the story. Scarlett Johansson and Amy Adams were also considered for the Marilyn role.
