Remembering is painful, it's difficult, but it can be inspiring and it can give wisdom.

In the end, it's acting, it's not real. But every director will tell you that you have to create conditions that create tension, because tension is what makes drama feel real.

You face challenges and you have to make choices. You're weighing the necessary responsibility toward reality and authenticity and of course the need to create a compressed drama over two hours.

There's a film you write, there's a film you shoot, and there's a film that you cut - and they're all different.

You sort of can't talk about the post production unless you talk about what comes first.

That's one of the central challenges we face - how to stay true to events and compress the fundamentals.

I always try and bring screenplay, shooting and editing into a sort of symbiotic - as close into alignment as you possibly can get them, consistent, obviously, with the resources that you've got and the time you've got available.
