Continuity mistake: The movie is supposed to have been filmed and taken place exclusively in Pasadena, TX, and MOST of it is. The trailer park that they live in, however, is NOT in Pasadena, or anywhere near there. There are several scenes where they show someone driving into the trailer park, and you can see mountains in the background. There aren't any mountains within hundreds of miles of Pasadena.
Continuity mistake: When Cole and the halfbreed duel with knives, the fabric they hold in their mouths as a tether keeps flipping over, meaning the end of the cloth hangs out the left side of the mouth, then the right, and left again - several times for both actors - even tho the fight is continuous and they make no moves that would change this.
