It's a combination of yes - making a movie about the characters - and then, also, budget.

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."

[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.

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."

I'm doing an over-the-shoulder shot on a dog. I'm putting the camera behind the dog's shoulder. This is craziness. You just accept it in the movie [Valley of Violence], but when you make the movie, it's the weirdest thing. There's dog coverage, like it's a person.

From a performance standpoint, it just gives [actors] so much - I had such a great cast [ in Valley of Violence] - and it gives them the ability to go wild with it and to have performances that are memorable.

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