Superheroes fill a gap in the pop culture psyche, similar to the role of Greek mythology. There isn't really anything else that does the job in modern terms. For me, Batman is the one that can most clearly be taken seriously.
For me, Batman is the one that can most clearly be taken seriously. He's not from another planet, or filled with radioactive gunk. I mean, Superman is essentially a god, but Batman is more like Hercules: he's a human being, very flawed, and bridges the divide.
In Hollywood there's a great openness, almost a voracious appetite for new people. In England there's a great suspicion of the new. In cultural terms, that can be a good thing, but when you're trying to break into the film industry, it's definitely a bad thing.
When you play a videogame, you could be a completely different person than you are in the real world, certain aspects of the way your brain works can be leveraged for something you could never do in the real world.
The thing with computer-generated imagery is that it's an incredibly powerful tool for making better visual effects. But I believe in an absolute difference between animation and photography.
I don't particularly enjoy watching films in 3D because I think that a well-shot and well-projected film has a very three-dimensional quality to it, so I'm somewhat sceptical of the technology.
I made 'Batman' the way I made every other film, and I've done it to my own satisfaction - because the film, truly, is exactly the way I wanted it to be.
The term 'genre' eventually becomes pejorative because you're referring to something that's so codified and ritualised that it ceases to have the power and meaning it had when it first started.
We all wake up in the morning wanting to live our lives the way we know we should. But we usually don't, in small ways. That's what makes a character like Batman so fascinating. He plays out our conflicts on a much larger scale.
I have been interested in dreams, really since I was a kid. I have always been fascinated by the idea that your mind, when you are asleep, can create a world in a dream and you are perceiving it as though it really existed.
As soon as television became the only secondary way in which films were watched, films had to adhere to a pretty linear system, whereby you can drift off for ten minutes and go and answer the phone and not really lose your place.
I have always been a huge fan of Ridley Scott and certainly when I was a kid. 'Alien', 'Blade Runner' just blew me away because they created these extraordinary worlds that were just completely immersive. I was also an enormous Stanley Kubrick fan for similar reasons.
For the last 10 years, I've felt increasing pressure to stop shooting film and start shooting video, but I've never understood why. It's cheaper to work on film, it's far better looking, it's the technology that's been known and understood for a hundred years, and it's extremely reliable.
I think there has been this increasing misperception that kids will not respond to something because it's also for adults. I think that often that tends to get underestimated.
But 'Memento' was so successful, such a huge cult hit, almost on the scale of a large film. If that had happened, with all the acclaim, before the next job, I'd have found it very difficult to figure out what to do next.
But I have been interested in dreams, really since I was a kid. I have always been fascinated by the idea that your mind, when you are asleep, can create a world in a dream and you are perceiving it as though it really existed.
But in the back of my mind I've always looked to the biggest-scale Hollywood movies. Because to me the most satisfying experience is of watching a movie, if it's done really well. And so that aspiration is always it for me, if I have the opportunity to do it.
My approach with actors is to try and give them whatever it is they need from me. Direction to me is about listening and responding and realizing how much they need to know from me and how much they have figured out for themselves, really.
But, in each case, as a filmmaker who's been given sizable budgets with which to work, I feel a responsibility to the audience to be shooting with the absolute highest quality technology that I can and make the film in a way that I want.
You know when Hollywood does a great big blockbuster that really wraps you up in a world, and lets you believe in extraordinary things that move you in some way, in an almost operatic sensibility? That to me is the most fun I have at the movies.
