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

I do think, even though I've made these genre movies, there's what happens in the movie and then there's what the movie's about. And for me, what the movie's about is so much more interesting.

There's nothing stopping you from making movies. You can always make and try different things.

You have to. But I generally try - I'll creep in the back. I'll be outside. I'll pace around. I don't really get that nervous about whether people like [my films].

That's what's interesting about people. It can be funny, but when [John] Travolta got there and did [comic moments] you're like, "Oh! This is really funny." Or when Karen [Gillan] and Taissa [Farmiga] do something, I'm like, "This came out so much funnier."

Jumpy is the most incredible animal of all time. The movie [Valley of Violence] is the tamest example of what that dog is capable of.

[Valley of Violence] was written for James Ransone. PJ's a friend of mine, I've known him for a long time, he's always like, "Dude, when are we going to make a movie together?" I finally called him.
