 A 24-acre cornfield outside Albuquerque was purchased to serve as the scenery for the climactic chase at the end, and that field was later added to the background of the Sommerton scenes.The chase had the problem of a snowstorm shortly before filming, which made the ground muddy and hard to drive on.On December 17, 2011, shooting of the film was briefly interrupted, but on January 3, 2012, it continued.
