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.

Yeah, we definitely have screenings; we just don't have screenings out on the street. We bring in - it starts internally, so its people who work at Bad Robot, then it starts going to our friends outside of Bad Robot, and then it starts going to friends of friends outside so we get really fresh people who don't have to pretend to like us.

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.

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

And then simultaneously I don't think they're asking you to necessarily write in stone that this is what you're going to do or what you have to do.

We were going to call it "Star Trek: The Avengers", and for a while we were like, "People are going to love that title". No, we had a whole bunch of titles, we never had any official title until we came out with this, we had different conversations about other things.

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.
