Audio problem: When Dianne is trying to seduce Bob early in the film, we hear her voice say, "You won't f*k me and I always have to drive", but her lips are saying something completely different. (00:18:35)
Factual error: The motel's billboard advertised HBO, which did not exist in 1971 when the movie was set.
Factual error: In the final flashback scene, which was no later than 1971 because Nadine was still alive, the Ford van is a distinctive style not introduced until 1975.
Factual error: The movie is set in 1971, but a fire extinguisher with modern pictorial labels can be seen when the detective is dusting for fingerprints in the drugstore.
Continuity mistake: After the quick close-up when Bob gets in the truck on the logging road, the clouds behind him change drastically.
Visible crew/equipment: Just before the first robbery, as Bob approaches the water fountain, the camera crew is reflected in the storefront window as they push the camera dolly.
Factual error: When Bob is looking for a room downtown, he walks past a trash can with a modern plastic cover that was not available in 1971.
