The most important thing about Olympics, of course, is the games and not the opening ceremony. It's weird the way it gets inverted sometimes.

The great thing about space films generally, with the exception of Apollo 13, is that big stars tend not to work in space and I think that's because space is an equaliser. It makes everyone the same really and suits an ensemble cast and actors who are prepared to work with each other.

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.
