There is just this need to feed the beast of movie, or TV, or whatever it may be and you don't want to do things just because you're supposed to do them, or because they're required, or whatever it maybe.

As J.J. has said many times, when you start a series you want to have a destination. It's like driving a car, when you pull out of your garage and you head out driving down the road, you have a destination, okay?

Screening is an invaluable part of the process, obviously, having test screening and you definitely learn something.

Well, truth be told it was the hope on the last one, it's always the hope. It's just you don't just wasn't to do it- everything we do is, for a lack of a more crass term, everything we do is pushing against the conveyer belt.

It's interesting because the way J.J. cuts - we're very close with our editors as well, so it's kind of the first cut and then he went back and started tightening things up, etc, then loosing things when it was too tight. Then you start watching it and you start figuring out performance - not performance, character-wise I should say, who you're really able to follow, whose journey is harder to follow, and you make all that work.

So that was an important part of the process and strangely, early on, we started to realize, in that respect, we were successful in what we were trying to do, which is make a film that everybody would be able come out and not be scratching their head at all.

Then we started looking at story and what was making sense and what wasn't making sense, emotionally and thematically the intention that we had a year earlier when they were working on the script, did all that come across? It's all kind of generic things, but it's fascinating and it's weird - I haven't made that many films, but it's weird that every time you think you learn from your mistakes on your last film you have a slew of new mistakes and things that you learn.
