One of the biggest changes for me on a practical level of shooting the film was having a second unit.

I've worked really hard to build up a career on my own. I turned 30 recently and it took me a long time to get the chance to make a feature film and do it on my own terms.

I've been working my way to doing my first feature film for about ten years. So I went through the commercials route and some people come from a theatrical background and some people come from a writing background, but I directed commercials

I was massively jealous but also excited when Tarantino did Inglourious Basterds, I'm a huge guys on a mission fan. Those kind of movies.

You are spending millions and millions of dollars of other peoples money when you make a movie. You have to at least approach it in a way where you can see how you can make that money back for the people who are investing.

The thing is that Warcraft has so much story available to it. For the fans, there are some key stories they really want to see on screen. I won't be doing those.

When I said that something was going to cost a certain amount of money, I actually knew what I was talking about. The biggest problem that we were having on the financing front was people with lots of money saying "you need more money to make this film [Moon]," and us saying "no this is the first feature film we want to do it at a budget where we sort of prove ourselves at the starting end of making feature films; we can do this for $5 million." That is where the convincing part between me and Stuart came, we had to convince people with money that we could do it for that budget.
