Michelle Williams glammed up on the red carpet of "My Week with Marilyn" premiere during the 2011 New York Film Festival. The former "Dawson's Creek" star who portrays the Hollywood legendary blond beauty in the Simon Curtis-directed drama stole the limelight as she arrived at the event that took place in the Hudson Hotel on Sunday evening, October 9.

Sporting a gorgeous pixie-cut blond hair, the 31-year-old Oscar-nominated actress donned a floor-length Dior vintage white dress with black accent on the waist. She was accompanied by her "Brokeback Mountain" co-star Jake Gyllenhaal who looked casual in a white shirt and brown trousers.

Another cast member spotted on the red carpet was Eddie Redmayne. The 29-year-old English actor looked dapper in a traditional two-piece black suit. Among the celebrity guests during the evening, there were Jamie Colby who opted a red dress and Elizabeth McGovern who wore a blue mini dress.

Based on Colin Clark's diaries, "My Week with Marilyn" follows the interaction between Marilyn Monroe and Sir Laurence Olivier during the making of 1956's film "The Prince and the Showgirl". The movie chronicles a week Monroe spent in London accompanied by Clark, who then became her secret lover, after her husband left her during their honeymoon.

Through her portrayal of Monroe, Williams received positive reviews from critics. The Hollywood Reporter wrote, "Michelle Williams gives a layered performance that goes beyond impersonation. Playing both the damaged, insecure woman and the sensual celebrity construct, Williams gets us on intimate terms with one of Hollywood's most enduring and tragic icons."

To open in limited U.S. theaters on November 4, the movie also stars "Thor" actor Kenneth Branagh, "Harry Potter" beauty Emma Watson, "James Bond" actress Judi Dench, as well as "Captain America: The First Avenger" star Dominic Cooper.
