The most extraordinary thing, you'd be given permission for, and then the weirdest, simplest things, you just wouldn't be able to obtain permissions. And it would go on and on and on forever and ever, and there was no way to know. You have to kind of approach it with an open, quite optimistic mind, no matter what's thrown at you, because it will only ever result in damaging the film if you let any kind of despondency get to you.

Good storytelling for me is not so much technical expertise, which I know is applauded often; it's actually freshness of approach. It does mean you sometimes stumble and fall and make a horrible mess of things in seeking that freshness, but you should always keep trying to do that.

The perfect equation is form equals content. The style of the film reflects the story, and that's what you're always aiming for. You're not always necessarily successful at it, but that's the ambition that you're trying to do.

Most films that I do, whether successful or not, just fade away. They have their moment in the sun, then they are gone. 'Trainspotting' did not, and especially with journalists. So whenever I launched a new film, I'd end up talking about 'Trainspotting.'

When you have children your own hypocrisy becomes more apparent because you're telling them how to behave, and you're not behaving like that yourself. So it obliges one to really go in and try to look at why there is a huge gulf between how one knows one wants to behave and how one actually does behave.

Brian Cox is the nicest guy, but he's so arrogant.

One of Dickens' biggest influences was the growth of London as a Victorian city, and the extremes being created as it expanded.
