Continuity mistake: When Loretta Lynn is at the radio station asking why the disc jockey had lied to them about playing her record, you see the picture of her that they took at home. It is a completely different pose than the one that you saw them take a couple of scenes earlier. She is looking in a different direction and she is not smiling as much as she was when they took it.
Continuity mistake: When Garland (Slim Pickens) finds out about the affair between Buck (Willie Nelson) and his daughter Lilly (Amy Irving). He takes a cab to the beach where Buck is hiding out. When Garland steps out of the cab, the bottle of tequila his is holding has just a little tequila in it. In the next scene when he is paying the driver the bottle is half full, and the next scene the bottle is almost completely full.
