What kind of training did it take to prepare?
Pilates was the ground floor. It’s such a good way of keeping your body safe. There is so much technique in fighting—how do you hold your fist, where does the motion come from. I had to learn to run fast—so we did a lot of explosive running. When we started filming, we kept the training up as much as possible. When you see a sequence that is 30 seconds long, it has taken weeks of preparation.
