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?

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.

So it's an interesting process just going through and seeing what works and what doesn't work, and what's the best version of it. It was a good process because I think we all collectively, when everyone would run into issues in the cut or know that things weren't working, they kind of glaringly stuck out so we could focus on fixing those things and it wasn't a situation where you would show it to ten people and you would have ten problems.

And more importantly what we found with those people is that a lot of them said, "Hey it's not what I thought it was going to be." Which is a great reaction, particularly if they liked it.

There's an overlap of people we've used from previous films and we also like to obviously bring in new people so we get a fresh voice and opinion when you bring them in. All different ages and genders and everything, you just want a wide spectrum of people who are coming in to see what works.

It depends on the project, what's happening that day on the project, at what stage were in on the project; it various from project to project and where we're needed.

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