It was pretty extensive - we worked out 8 hours a day, 5 days a week, for 3 months, which I think is more than anybody in the Olympics. I thought well I don't need this, the girls need it, but it was a gift.
The magic doesn't come from within the director's mind, it comes from within the hearts of the actors.
