Factual error: Then, as now, every recruit reporting to boot camp would be tested for illegal drugs, first by a urine test and then by a broad spectrum blood test in the case of a positive result. There is no reason for Elmo to try to hide his stash when the recruits are told they are to be tested - he is going to come up positive anyway. He may as well just say he has changed his mind and walk away. He is entitled to do that any time up to ten days after he signed on, and it happened a lot in real life!
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)
Continuity mistake: In Jack's first appearance to David in the hospital room, Jack uncovers the food on the tray and takes a piece of toast from another plate on the tray. The silver cover on the tray changes position throughout the scene in various shots. Sometimes the cover is resting partly on the tray and sometimes flat on the tray table surface.Randy DeShong
Continuity mistake: About half way through the movie, the three main characters are in a loft. When the Asian girl grabs the postal worker's jacket, a cassette tape falls out of his pocket. As the girl bends down to pick up the tape, the camera shows here reaching with one hand, and then the camera switches to a close-up of her picking up the tape with the opposite hand.
