Right whenever Big Apple's pride explodes. near the bottom of the building there is tiny group of lights, watch them!!! 1)They explode 2)The camera changes scenes and they explode again 3)The camera changes scenes again to the whole building do see the lights? See them. Watch as they explode again!!!
Actually, there are several more similar shots in the film: cars falling and crashing, or the N.Y. mounted policeman turning around in panic, other explosions, etc. All these scenes have been shot from different directions and used again and again, repeating themselves.
The three camera angles were from three different cameras, all filmed the same thing. Like when Evil Kenevil jumps, they show four different camara angles; he didn't jump four times, did he?
