Continuity mistake: In the final scene of the movie, on the highway, Cora (Jessica Lange) is ejected from the car Frank (Jack Nicholson) is driving, hits the ground, dies instantly after the impact, and rolls over to the shoulder of the road. Weeping, Frank kneels by her side and holds her motionless right hand with his right hand, which, of course, has no wedding ring (They had just been married.) The next and last close-up shot shows he's holding her right hand with his LEFT HAND, the wide gold wedding ring appearing now in full sight. (01:59:33)
Other mistake: Toward the end of the film, Cora and Frank put the top up on their roadster, then drive off without latching the top.
