I really love that film. Second best in the world! Next to Vanilla Sky
I understand what you mean, though I'm not 100% how the effect could be reproduced. However, in films like Gladiator, during the fight scenes, to make them look faster paced they actualy removed every other frame, and then sped it up. It gives everything a much more frantic look. But to pull it off, you need to use really short shots, no more than a couple of seconds long, else it'll just look a mess.
