You don't have to fight to be brave. Millions of good, fine, decent folks show more bravery than heavyweight champs just by getting out of bed every morning, going out to do a good day's work and living the best life they know how against the law of odds.
I want to play a real man in all my films, and I define manhood simply: men should be tough, fair, and courageous, never petty, never looking for a fight, but never backing down from one either.
When you stop fighting, that's death.
This kind of war, you've gotta believe in what you're fighting for.
