If you saw any of the Tom Cruise-starring Mission Impossible movies then you know just how brazenly reckless Tom Cruise can be when it comes to performing his own stunts. Cruise went as far as firing his own insurance company so he could perform some of the stunts he executed in the franchise. Having spoken to a few stuntmen, it's all about the rush. Once you start doing it, it's very hard to stop. Much props to Cruise, I don't think anyone else in Hollywood goes to the extremes Cruise does in trying to make his action scenes look as genuinely realistic as possible.
