In the opening credits James Magnum Cook is referred to three times as a Producer in a row. The mistake was not caught until the DVD had already went into Production.
During a fight scene between Sheriff Jake Madison and Reporter Laura Donovan in Madison's Office at a Fictional Hotel you see a brief cut back to when Donovan first entered the room. Since the final film was made into a Grindhouse style film it was felt it could be gotten away with and you have to look or slow the film to notice it completely.
