Michelle Williams has another trophy to put on her mantel.
The My Week with Marilyn star earned best female lead for her on-screen transformation into dazzling blond icon Marilyn Monroe Saturday at the 27th annual Independent Spirit Awards. Accepting the award, she joked about how she wore “her own clothes” and cut “her own hair” when she came to the ceremony for the first time 10 years ago.
But the Indie Awards’s biggest winner was The Artist, which took home the afternoon’s top honor, best feature.
Jean Dujardin was also recognized as best male lead in the black-and-white silent film. The Frenchman already took home wins for the film at the Golden Globe Awards, the Screen Actors Guild Awards, the BAFTA Awards and Cannes Film Festival. French cinematographer Guillaume Schiffman also won for his work on The Artist, as well as director Michel Hazanavicius.
Also winners at the Seth Rogen-hosted Indie Spirit Awards: Shailene Woodley and Christopher Plummer for their supporting roles in The Descendants and Beginners, respectively.
The awards ceremony will air on TV Saturday (10 p.m. ET/PT), exclusively on IFC.
