Of course, her greatest film role was as Mrs. Danvers in REBECCA but she was also memorable in LAURA as Ann Treadwell. She also played Lady MacBeth, Gertrude in Hamlet, Medea (who kills her children to get revenge on her husband) and Slade in Lady Scarface. In the STRANGE LOVES OF MARTHA IVES, she plays a cruel aunt who torments a cat. In AND THEN THERE WERE NONE, she drives a young man to suicide.
You can't help but wonder if an actress without classic beauty got offered very different parts.
