You want to be able to say [to Ethan Hawke's character], "Dude, it's okay," but maybe it's not. Maybe he's not a good person. I don't know. That's the thing about people. There is no real good guy or bad guy [in A Valley Of Violence]. It's all context.

Typically, in Westerns, people who are in a Western feel like they're in a Western. It's almost like they know they do all these Western things.

Tommy Nohilly, who plays Tubby [ Valley of Violence], he came down to see the movie for the first time and I was like, "You've got to come just to see people react to your [big scene]." I knew that would go well, but it's satisfying to me when he's sitting there and it actually does.

They're both [Ethan Hawke and John Travolta] so good. It's hard to explain. But they're consummate professionals and you see the little choices they make - you see it in their eye. You see these little details they do where you go, "That's why they're them."

It definitely could have been a horror story [Valley of Violence], oh my God, if the dog was impossible. So could the horses.

The hardest animal was the vulture. But the horses were great, the dog was great [in Valley of Violence]. It was really easy.

The first half [of Valley of Violence] was to endear you to all these people and give you all these archetypes that you're familiar with, and then the second half, just to see all those archetypes unravel like real people.
