Most of us have heard of "Murphy's Law" by now. It goes; "Anything that can go wrong, will go wrong." It most circumstances the outcome of "Murphy's Law" is little more than a minor inconvenience. The package delivered to the wrong address in spite of repeated instructions, bad weather when you have just lost your cover set, you can think of a hundred other situations. In film production, holding Murphy at bay is a full time concern.
But on big city streets, at night, doing major stunt work, Murphy may have a much darker side.
