How “The Fighter” shot 35 days worth of fight scenes in only three days →
April 4, 2011
They used a crew from HBO that films actual fights. Matt from 37signals quotes from the DVD commentary:
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 have the luxury of showing them what we’re going to do in the morning before we shoot it and doing it over and over and over again. So why do you need 20 days? For what? To jerk each other off? To touch up your makeup? To go in the trailer and take a nap?
