Deliberate mistake: At the beginning of the movie while driving through town the old rusty horse trailer was facing from left to right. at the end of the movie as they were leaving town, they showed the same trailer and the picture was inverted, parked in same location,however it was facing right to left.
Deliberate mistake: In the scene where Cotton and the film crew are travelling to the Sweetzer farm they pass an old decrepit horse trailer the trailer is facing the right of the screen. Later when they are leaving the farm, the trailer is facing the left of the screen. The shot is just flipped from earlier on.
