Sure I agree that Joan Crawford was too old for THIS part, which required a 20-something bored with her slug of a husband. Then wanders off and has men chasing her skirt basically 24/7.
Nevertheless - and most ironically - the decision to strip her of the usual five layers of war paint reminds viewers just how ridiculously good-looking Joan Crawford was. And pardon me for saying so,but I had no problem - None Whatsoever - believing Joan with a more natural look, parading around in model's lingerie or dinner clothes, and sporting a cheeky attitude, would have men falling all over themselves.
She is, quite simply, a drop-ded s3xy woman, regardless of age.
As her character gains confidence with the hustle, her character just gets more interesting. And more attractive.
There's a plot involving an accountant but who cares. Those are details.
