Joan Crawford
I love this film and I always enjoy watching it, but it wasn't until recently that I read Joan Crawford had campaigned to play the role of Helen, but Louis B. Mayer refused, as he didn't want her playing another "cripple" or "maimed woman", as he put it.
I'm just wondering how they managed to convince Crawford to give up her campaign, as she also owned the rights to the story, and badly wanted the part after receving acclaim for A Woman's Face.
That aside, I think Dorothy McGuire did a great job as Helen, but it's interesting to imagine what Crawford would have done with the part. I imagine her Helen might not have seemed as vulnerable as McGuire's did, although in Mildred Pierce, Crawford made Mildred very sympathetic and gave an excellent performance.
Maturity. The very staple of the IMDb message boards.
