from Wikipedia: My Week with Marilyn is an upcoming British drama film directed by Simon Curtis and written by Adrian Hodges. It stars Michelle Williams, Kenneth Branagh, Eddie Redmayne, Dougray Scott and Judi Dench. Based on two books by Colin Clark, it depicts the making of the 1957 film The Prince and the Showgirl, which starred Marilyn Monroe (Williams) and Laurence Olivier (Branagh). The film focuses on the week in which Monroe spent time being escorted around Britain by Clark (Redmayne), after her husband, Arthur Miller (Scott), left the country.

Principal photography began on 4 October 2010 at Pinewood Studios. Filming took place at Saltwood Castle, White Waltham Airfield and on locations in and around London. Curtis also used the same studio in which Monroe shot The Prince and the Showgirl in 1956. My Week with Marilyn had its world premiere at the New York Film Festival on 9 October 2011 and was shown at the Mill Valley Film Festival two days later. The film will be released in the United States on 23 November 2011 and on 25 November in the United Kingdom.

from www.dailymail.co.uk – She admitted that filming the movie left her in tears at the end of each day.

So it is perhaps little wonder that Michelle Williams has seemingly laid to rest her inner Marilyn Monroe, who she portrayed in her new movie, My Week With Marilyn.

Last night there was not a hint of the tragic Fifties screen siren about Williams as she stepped out to a screening in Hollywood at the 2011 American Film Institute Fest.

With her pixie blonde hair and structured gold dress, the 31-year-old actress was championing a style of her own – and was certainly not borrowing tips from the flouncy and seductive Monroe.

And while Marilyn might have oozed sex appeal, Michelle – who would spend three hours in hair and make-up being transformed into the starlet when shooting the movie – says her cropped hair is something that turns men off her.

In a recent interview with Elle, she confessed: ‘What [my daughter] Matilda would love is for her mom to grow out the cropped hair, though that’s unlikely to happen any time soon.

‘I’ve really grown into it – I feel like myself with short hair. And it’s been a really long time since I had long hair, five years.

‘Of course, the only people who like it are gay men and my girlfriends. Straight men across the board are not into this hair!’

My Week With Marilyn documents the tense interaction between legendary actor Sir Laurence Olivier and Marilyn Monroe during production of 1957 movie The Prince and the Showgirl.

Olivier was reputedly so annoyed by Monroe’s diva-like behaviour on set that he practically abandoned directing for the screen, only returning in 1970 to make Three Sisters.

The 1957 movie was a financial success, though it was panned by critics for being slow moving.

Williams revealed that she would spend three hours getting transformed into Monroe when shooting the biopic.

‘You’d think playing Marilyn Monroe, you’d be in full-on goddess mode,’ she told Newsweek recently.

‘When I washed my face and took my make-up off at the end of the day, there was some sort of horrible Frankenstein staring back at me.’

The elfin star also had to put on weight to embody Marilyn’s curves, and bleach her hair blonde every few days to avoid showing roots.

Understandably, this difficult role led to Williams waking ‘up in cold sweats in anticipation’ after taking the role once she had been persuaded by director, Simon Curtis.

She also revealed that playing the doomed star, who was 36 when she died of an overdose in August 1962, was emotionally draining too, admitting that sometimes after a day’s filming, she would cry on her way home.

‘The other day, someone asked me how I got her sadness,’ Williams said ‘I don’t think I ever cried so much for somebody I didn’t know.’

Harry Potter actress Emma Watson also stars in the movie as a wardrobe assistant.

She was not at last night’s screening – but other stars of the movie who turned out included Julia Ormond and Dominic Cooper.
