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.
