I never told my father I loved him before he died, and I have a lot of issues about that. They're all swimming around in my head, in my heart, unresolved, and in a way it felt fitting to dedicate the film to him.
It's a shame about California, and particularly about L.A., where they've demolished so many landmarks. It's a bit of a disease there, where if anything is over 30 years old, they sort of knock it down and replace it. It's a strange town, it's this sprawling suburb, and then there's a city, the old town.
I wanted to play Dracula because I wanted to say: 'I've crossed oceans of time to find you.' It was worth playing the role just to say that line.
The thing a drama school can't give you is instinct. It can sharpen instinct but that can't be taught, and you have to have intuition. It's an essential ingredient.
When I decided that I might want to do acting for a living - I don't know where it really came from, since there was no school play or any of that - my mom gave me her blessing. I had to get a scholarship - that was the only way I could have gone to drama school.
I drank for about 25 years getting over the loss of my father and I took the anger out on myself. I did a good job at beating myself up at sometimes. I don't drink anymore but my alcoholic head occasionally says different. 'Nil By Mouth' was a love letter to my father because I needed to resolve some issues in order to be able to forgive him.
Rather like Batman, I embody the themes of the movie which are the values of family, courage and compassion and a sense of right and wrong, good and bad and justice.
A lazy man works twice as hard. My mother told that to me, and now I say it to my kids. If you're writing an essay, keep it in the lines and in the margins so you don't have to do it over.
At the Oscars, if you didn't vote for '12 Years a Slave,' you were a racist. You have to be very careful about what you say. I do have particular views and opinions that most of this town doesn't share, but it's not like I'm a fascist or a racist. There's nothing like that in my history.
At 23 it was all about acting. Today it's getting my kids to school, making sure that they've done their homework. I'm in my fifties, and I'm turning into a square.
There's no handbook for parenting. So you walk a very fine line as a parent because you are civilizing these raw things. They will tip the coffee over and finger-paint on the table. At some point, you have to say, 'We're gonna have to clean that up because you don't paint with coffee on a table.'
As a drama student I got into Thirties and Forties suits.
You take what you know, and you put it through your own prism. If I play characters that break down or cry, it's Gary Oldman crying; it's not the character crying.
Wanting to be a good actor is not good enough. You must want to be a great actor. You just have to have that.
But you see, I have played more good guys than I have played villains.
So Harry Potter came in and it is nice that I have kids of the right age. I took them to London and they walked around the set and met Harry Potter and that is thrilling.
And of course I've got kids of my own now, and they love me being in the Harry Potter films. I'm now part of a phenomenon. You become incredibly cool to your kids, and you get a young fan base. So you became the cool dad at school. You're suddenly hip.
Interesting things come your way but as you get older, your lifestyle changes. I don't want to travel; I don't want to be in a hotel room away from my family.
I wasn't ever a huge fan of comics. Just not one of those kids, you know?
Change is vital to any actor. If you keep playing lead after lead, you're really gonna dry up. Because all those vehicles wean you away from the truths of human behaviour.
