The owners of the Hawthorn Funeral Home in Carthage, Texas, where Bernie Tiede met Marjorie Nugent, refused to allow the film to use the name of the funeral home.
When Bernie is driving up to Mrs. Nugent's home, there is a close-up of the Texas State Registration sticker on the front windshield of the car which clearly says "12, 11" indicating that the registration will expire in December of 2011.
(at around 1 min) When Bernie is on the phone with Lloyd, there's an Apple Macbook Pro (Second Generation) in front of him. The Second Generation Macbook Pro didn't come out until late 2008 and the murder took place in 1998.
Townsperson: Well, I know the Bible says Jesus turned water into wine, but it didn't say liquor store wine. It had to have been non-alcoholic wine, because it didn't have time to ferment.
Townsperson: Well, Bernie was so nice, so accommodating, so willing to keep from hurting other people's feelings, he just couldn't tell anybody to piss off.
