I would say that maybe directors who act as well are easier with actors. I'm not saying that all directors have this, but sometimes you'll come across a director who sort of looks at an actor a bit like a kind of untrained horse that's been let out of the stable, like they might buck him.

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.

I've played an awful lot of repressed people.

I think loads of people see acting, when they're kids, as these magical stories that just happen within the context of the film or the play or the cartoon or whatever they're seeing. They don't imagine that there are actually people that go and do that for a living.

I don't want to make vast generalizations about people who go into legal professions, but there are similarities in the barristers that I met and interacted with, in the sense that they tend to be highly eloquent, highly analytical, thinking people who have a very rapid-fire think-before-they-speak button, as it were.

I don't like talking about myself, if I'm honest.

Whenever I'm in theatre situations I will go out of my way not to talk about my father, but in the film world I can be really proud of my family and say, 'You know what: my dad's a really, really famous theatre director,' because nobody has any idea.
