When Joyce escapes the car when she is hitchhiking, she threatens the man with a weapon (nail file?) in her right hand in the long shot. In the close shot, the weapon is now in her left hand.
At final scene at the hut, a medium shot shows sunlight and shadows and is followed by a long shot where the sun has gone and there are no shadows.
Joycie wears Capri pants made of denim. Although Capri pants started to become popular in the 1950s when the film is set, denim would not have been used until the 1960s.
