Can you name this piece of classical music?

This is going to be tough, but I can't think of a better way to describe it. They play it in basically every movie when something goes crazy, or all hell breaks loose. It starts of with strings on their own, then as the craziness grows, other instruments jump in.

It repeats basically the same string of notes over and over again, just adding more instruments and getting louder as it grows.

Any ideas?
