Continuity mistake: In the scenes at the beginning where Willy Jack is in the car his shirt changes 3 times before he's finally pulled over with the 14 year old girl. It's all one day. (00:14:00)
Suggested correction: This is not entirely unusual. A person might change their shirt, more than once, if the weather is making them sweat. Especially if the car does not have AC. Novalee said that Willy Jack bought the car very cheap, and there is a hole in the floor, so I would not be surprised if the AC was broken.
I second this. My husband owned a car that didn't have AC, and it was not unusual for him to change his shirt on hot days.
Continuity mistake: When Pollock is filmed painting, the boots he is wearing change to shoes, then back to boots again.
