Referring to the shoot as "a week of this madness," Darabont explained, "Instead of looking at the storyboards, I was just making it up as I went along." Gamble added that during the scene when he evaded the “dinosaur-ass-looking thing that is stomping its way towards [him]” he "banged off of the sections of the aisle" and hit his head on the ground hard enough to bruise.
