During filming, Arnold Schwarzenegger was seen purchasing clothes at Walmart. They were for the film's crew, as it was freezing during the night-time scenes in the desert.
The film was a box-office disappointment, but turned a profit from DVD and Blu-Ray sales.
In the scene where the Sheriff and his newly deputized force are arming up, Luis Guzmán can be seen with a mace and chain stuck in his belt and a sword. The sword is the same design as the one Arnold Schwarzenegger used in Conan, le barbare (1982).
