Shelley Duval Cloned from Keely Smith?
Watching the scene of Mitchum and Smith sitting on the couch watching the rain, discussing the philosophy of the natural freedom to make 'shine and the benefits of military service. If you don't know better that has to be Duval. At least sisters, but you can argue for clones too.
Nice singer, I knew the name but don't think I ever heard her perform before. Her hair stylist did her no favors.
