It's this long monologue [in Valley of Violence] with Ethan Hawke talking about life and everything with a dog. That's not in movies. Hopefully when people think about the movie when they go home, they're like, "That's weird. He's maybe crazy. He's talking to a dog the whole time."

Everything Jumpy could do [in Valley of Violence] was too much. If I put it in the movie you would all check out. When he wraps himself up in the blanket, that's as far as I could go, and that's not even close. The dog's amazing.

The second half [of Valley of Violence], you're with the guys that you should hate, but when you start seeing what their real lives are, you're like, "I do hate you, but at the same time, all right - maybe take it down a notch." The complications of all that are what's so interesting to me, those esoteric details - that's what people will hopefully take away from the movie.

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.

All those awkward moments - that's on the cast for doing such an amazing job. I think it was funny on the page, but when they did it, you definitely went, "Oh!" Watching it with a crowd that, like you said, was not expecting it to be funny, but then genuinely finding it funny, is totally a credit to their performances.

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.

I found Jumpy on YouTube. I wrote a movie about a guy with a dog and was like, "What have I done? This is going to be a nightmare. We're a small movie and we're never going to be able to do this."
