You do look at a lot of movies and many characters seem to be interchangeable.

I was also a science fiction and fantasy fan, growing up, in games and books and movies. I love Tolkien and I love Dungeons & Dragons, so the opportunity to have a fantasy-based RTS, or real time strategy game, at that time, seemed cool. I started playing it, and the early games were simple, but fun and they had these great heroes.

For me, two of my favourite science fiction films are Blade Runner, which is fantastic, and Terry Gilliam's Twelve Monkeys. Both of those were smart science fiction films hitting more of a medium budget, and I desperately hope there is an audience for that kind of film because I would love that to be my next film, on that kind of scale.

I think there is also a certain degree of expectation that's set up by trailers, where even if you know what's going to happen in parts of the film based on the trailer, you almost anticipate and look forward to those moments based on having seen the trailer.

Maybe there is a sort of a sweet middle ground there, where you can do something with something with like 20 to 40 million and do something which is much more character driven, but still create a sort of visual spectacle around it. That is what I'd like to do.

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

Sometimes there's a disjoint between what works on the page and what works with visual story telling.
