 The reenactment of the post tornado stricken landscape was filmed in  New Orleans, Louisiana utilizing the natural disaster left over from  hurricane Katrina in what is locally referred to as "New Orleans  East". The neighborhoods in which filming took place was regularly  patrolled by the National Guard in humvees as the area was without  power and some residents were attempting to rebuild only to be  robbed as they attempted to piece back their lives. Filming was  during the summer of 2006.
