You might make a lot of money, but it's very hard to get out from under that rug. The more you can reinvent yourself, the better - and unfortunately TV is designed not to let you redesign yourself.

You don't reinvent yourself; you get better with what you do.

I don't want to be knocked out. But the contact and the focus and the energy I get from sparring gives me energy to make movies, energy to be a dad, energy to be a friend, and, you know, makes me feel, probably, a lot younger and behave a lot younger than I am.

If you're a 50-year-old guy, and you're sitting around the house with - you know, and just getting fatter, feeling sorry for yourself, get up and move your body and see what it does to your life and to your mind and to your happiness and to your energy levels. And I get all that from boxing.

Unfortunately, if you don't want to be in the spotlight, get out of it.

I had great luck with Tim McGraw twice in 'Friday Night Lights' and 'The Kingdom.' I love finding off-beat casting and finding someone you know in one way and you reinvent them in another way. I like doing that as a director.
