Michelle Williams wore brand new Dior and shared the red carpet with her My Week With Marilyn costar Eddie Raymayne last night during their premiere at the New York Film Festival. The Marilyn Monroe biopic debuted at the Big Apple celebration and will be released in theaters on Nov. 4. Both Eddie and Michelle hit a Dior-sponsored party following the screening. At the bash, Michelle reunited with her good friend and former Brokeback Mountain costar Jake Gyllenhaal. The My Week With Marilyn reviews so far seem favorable, and there is a particular buzz about Michelle's portrayal of Ms. Monroe. If she scores an Oscar nomination in 2012, it will mean her second in as many years following her 2011 nod for Blue Valentine.
