I can now officially to the wife It's work, darling I have to watch racing. I have to watch every second. And actually, my wife who can't stand racing has got into it and once she understood the politics it becomes more interesting for non-racing people I think.

There is so little time on a set to build up a working relationship with a new member of crew. It is tough to be polite, especially in an extreme location where we will not get a second chance to get the scene. It is such a stressful process that I like to work with people I know and can trust.

I love sport, so I'd love to do more stories if I can that deal with sport maybe. Other characters, actually the real guy is so interesting why would you want to get anyone to play them?

I used to work in TV and quit the job because I couldn't do it any more. I quite like taking my time over a film, five years is how long it takes me to work something out. And when you just do quick turnover, turnaround, I'm literally this is driving me mad, I want to find another living. I'll just have to find a creative way to tell the story.
