OTRC: Michelle Williams dons Dior gown with black belt to 'Marilyn' premiere (Poll)

Michelle Williams wore a light green chiffon Christian Dior gown with a plunging neckline and a black belt to the premiere of her new film, "My Week With Marilyn," at the New York Film Festival over the weekend.

The movie is set to hit theaters across the United States on November 9. Williams, who rose to fame with a supporting role on the WB series "Dawson's Creek," portrays one of Hollywood's most famous leading ladies and sex symbols, Marilyn Monroe, who died in 1962 at age 36.

"My Week With Marilyn" is based on the week that British writer Colin Clark worked as Monroe's assistant while she was filming "The Prince and the Showgirl" in the United Kingdom in the summer of 1956. British actor Eddie Redmayne plays Clark and accompanied Williams to the premiere.

Williams, a 31-year-old Montana native, is also known for movies such as "Brokeback Mountain," which starred her then-boyfriend Heath Ledger and the R-rated "Blue Valentine." Both movies earned the actress Oscar nominations.

Williams also recently filmed the independent movie "Take This Waltz," which was directed and written by Sarah Polley and also stars Seth Rogen and Sarah Silverman. No wide release date has been announced.

Williams is currently shooting the fantasy film "Oz: The Great and Powerful." Production began in July. Williams plays the witch Glinda, while James Franco plays the title role of the wizard. The movie also stars Mila Kunis and Rachel Weisz and is set for release on March 8, 2013.

Williams recently said in an interview with Hobo magazine that she often dreams of "quitting acting," adding: "Walking away and becoming a laundress or a sous chef or maybe writing other people's love letters for a living. Clearly, I don't like to be in charge. And thinking of quitting is just keeping going in disguise. When you have options, anything is bearable. It's when a situation is inescapable that it becomes hell."
