Continuity: During the opening scenes, Beth Heke is walking past the yard where some men are working out with weights. One man is "spotting" the other man who is doing bench-presses. As the camera changes angles, the man who is spotting changes from spotting with his palms facing down to actually doing "curls" with the bar that the other man is pressing up and down. Each time there is a change in the camera angle, his grip on the bar goes back and forth from palms-up/curling to palms-down/shoulder shrugs. This happens several times.
