Authenticity of “The Fighter”

Mark Wahlberg:

And what I kept telling everybody is that HBO does it in one take and they don’t know what’s going to happen and they never miss a thing. … We’re not talking about putting the camera in there and saying, “OK, we’re going to do a stunt punch here.” No, we’re going in there and beat the shit out of each other and we’re going to make it real.

This is how they shot all the fight scenes of The Fighter in three days, instead of the conventional thirty-five. And judging by the film’s success, it was for the better.
