Anyone else noticed a flaw in the movie?
The elevator killer kills women in such a way that the brain dies last, enabling David Warner's character to keep the brains.
At the end, Kathleen Turner becomes a victim of the Elevator Killer, and Steve Martin uses her body to be put Amy's brain into. Well, for THAT to work he'd have needed to kill Turner's brain FIRST, not last.
I've seen the film 13 times, and it's always bugged me about it!
