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.

Both of my sisters have been teachers and they used to say you get asked between 300 and 600 questions every day which you have to answer. That's exactly what directing is. And the vast majority of those questions are not very interesting really, but they need somebody to make a decision - a good one or a bad one - and they follow it.

I was brought up a very strict Catholic and I don't practice anymore or anything.

There are three huge, titanic, space movies which if you ever make a film [about space] you cannot avoid. You may want to avoid them but you cannot. I've never known a genre like it where you are dictated to by these films, 2001, Alien, and Tarkovsky's Solaris.

One of the things in the Mary Shelley [Frankenstein] is that the creature tells his story, so this begins with the creature's point of view. So, it literally starts with the creature opening his eyes and is born - but is obviously in his 30s. But because they're the creator and the created we thought it would be really interesting if they could look at each other every other night and play each other's roles.

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.
