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.

Basically, actors arrive in a bubble. They have a little sealed bubble around them and it's basically [comprised of] their agents, their last film, their next film, their press agent, and their per diems - all these things, they cocoon themselves with and you have to puncture that bubble on each of them to make them be in your film.

I love that sense of change that you'd get in pop music every three minutes, every four minutes.

I'm not a 'Star Wars' geek.

You can do anything you like - really - but this Sci-Fi is absolutely disciplined, it's Zen, you have to be absolutely focused in an area. You have to zone into an area and you then you can achieve when you get there. It's really weird!

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.

You can't tell someone they are wrong about their own life.
