Carole and Stefan
I know it's how they made films in those days, but I can't take the always immaculately coiffured couple seriously as actual people. I mean, can you imagine them "on the job"? They get married after knowing each other for only a short time; even if Carole wasn't a virgin their wedding night probably was their "first time"; there were bound to have been some alignment issues.
I'm not expecting a sex scene; just for them to be a bit more believable as a couple.
