Maybe it's a little ambitious of me to presume that no matter how big the film is, that I can always go down to the shop to buy a pint of milk.

I spent my entire experience with Gary on Tinker Tailor Soldier Spy staring at him and not returning any lines because I think he's God. The second time on The Dark Knight Rises I was playing God, so I ignored him. Kicked him a bit, that kind of thing. Gary Oldman is one of my heroes, I did nothing but glean from him.

I'm from East Sheen, I went to public school where I learned Latin at the age of nine, and certain expectations were made of me to go to St Paul's, Oxbridge maybe, and all that kind of thing.
