I love the solitary, romantic idea of writing.

One of the great things about the 'Iron Man' franchise is that they employ fascinating actors who don't necessarily do action movies. Before 'Iron Man' you didn't associate Robert Downey, Jr. and Gwyneth Paltrow with those kinds of films. There's an emphasis on repartee and wit.

There are people all over the world who like to write fan letters in the voice of their pet: 'Hello, my name is Fifi and I'm a labrador and I think you're great. Paw paw!'

In high drama or high tragedy or anything, it's not really human unless there's some humor at the same time. And vice versa. So I guess I tend to gravitate towards projects which tread a dodgy tightrope between two things, which aren't really one or another.
