British Accent
The Jean Simmons performance in this film illustrates how movie performances have changed over the last 50 years. These days it would be hard to imagine a film with a lead actress who can't properly speak in the accent of her character. Jean's character is supposed to be from Middle America but speaks with an accent that could be described as mid-Atlantic at best. That would never happen today - not since Kevin Costner tried to do Robin Hood. If this movie were to be made today and somebody like Kate Beckinsale were to play the role of Sharon, you'd never know she wasn't American.
