I have this theory that your first film is always your best film in some way. I always try to get back to that moment when you're not relying on things you've done before.

A lot of film directors are quite scared of actors. They are a bit of a nightmare sometimes, but I like them. It looks like cunning, but you try to get extra things from them all the time, by stealth, by making them feel confident, so they trust you and you can push a bit.

But interestingly Star City's technology is all 1970s - still. In fact, it's alarming because you think, "You're not going to send someone up into space in something that old, are you?" But it works and it always has worked and it doesn't fail and it's incredibly reliable.

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.

I'm a big sports fan. Football. Cricket.

I always felt it is not good if you feel like you would know how to do something. I've made mistakes of telling people: I know how to do this. And it should feel dangerous. That is the only way to stay alert, to keep the adrenaline running.

Clearly, you can think back and see that a character has had enormous odds stacked against him and has to overcome them. It's usually a guy, I'm afraid. But then you're setting up a new movie you have amnesia about these meetings, when you've discussed it more analytically.
