 On 10 December 2004, a set in the Tucson Convention Center (TCC)  being used to film a mine collapse caught fire when the special  effects department made a big mistake. Five people were injured, two  of them enough to need hospitalization. The fire destroyed  everything on the set, including all of the production gear and  equipment, and the TCC sustained heavy water and smoke damage. The  invitations to the premier screening said "the film that set Tucson  on fire."
