*Front: The steel-and-concrete office buildings of Los Angeles are blasted into oblivion. For scenes such as this, models of cities were tilted toward a remote-controlled camera, shooting at high speed, which was placed on a scaffold near the ceiling. Then, a fireball was ignited below the model sending flames over the tops of the buildings.
