The film opens with a three-minute, twenty-second tracking shot widely considered by critics as one of the greatest long takes in cinematic history. On the U.S.-Mexico border, a man plants a time bomb in a car. A man and woman enter the vehicle and make a slow journey through town to the U.S. border. Newlyweds Miguel “Mike” Vargas (Charlton Heston) and Susie (Janet Leigh) pass the car several times on foot. The car crosses the border, then explodes, killing the occupants.
