I'm not really a director for hire. You read these scripts and go, 'This is a really great script, but Paul Greengrass would make this so much better than me.' I usually say, 'I know who would be good for this. It's not me.

I am, in fact, Superman. Every morning I wake up and go into a telephone booth and change my costume, and then go to work.

Actually, to be honest, this is a useful time to not be knowing what I'll be doing in 2013 or 2014, because really, for the last however many years, I've known what I've been doing for years and years ahead. You get into a cycle of non-reflection, and that gets a bit scary.
