Funny you should mention The Maltese Falcon. I've always wished another actress had been cast as Ruth Wonderly. I just never bought Astor as a femme fatale, especially in TMF. For the life of me, I could never figure out why Sam fell for Astor's Ruth, or her treacly-sweet helplessness.

Not sure who I'd cast instead -- maybe Ida Lupino? She could play very vulnerable with those big, luminous eyes, but she also that tough, brittle edge. Or, I would've loved to have seen someone like Joan Fontaine really stretch beyond her usual sweet, innocent roles.
