Some jobs you do, they're just jobs. Others are life experiences.
As an only child, particularly if you're a boy without a father, you have to work out for yourself who you're going to be. And I do think, over the years, I've developed a need for control.
I'm sure, in real life, spying is boring - there's probably a lot of sitting around and plenty of paperwork. But the world seems to think that spying is exciting, and that's how movies get made.

Funnily enough, I had a real giggle with Gary Oldman when we were doing an interview together for 'Tinker Tailor Soldier Spy.' Because I joked I was probably the only British actor who wasn't in the 'Harry Potter' franchise. The same is true of 'Game of Thrones.' Also 'Star Wars.'

There's an honourable tradition of British actors who've gone to Hollywood playing baddies. Part of that is because we grow up with Richard III and Macbeth - we're not afraid of our villains.
For me, family comes over and above everything.
