I've always been interested in the idea of people who fell through the cracks.
We don't consider the Wizard of Oz or Father Christmas to be too old. They're still magical characters, and the fact they've been around the block only adds to their magic.
I'm so lucky to have worked with Burt Lancaster, who I remember was one of the first people I'd heard swearing in a really interesting way.
There is no such thing as too much swearing. Swearing is just a piece of linguistic mechanics. The words in-between are the clever ones.
The biggest thing I have realized was that you have to choose your collaborators very carefully, and that not everybody can like you. The process of filmmaking is so difficult, there's no point in doing it unless you can do it the way you want.
Drawing is the only thing I've found in which I can lose myself completely. I love it. It started as something that relaxed me, but now it's a struggle because I'm pushing myself. The day-to-day sketching is fraught.
Comic-Con is so legendary, so a great thrill to be invited along.
I was always admiring people who seemed to conduct themselves with ease in the world. Maybe that's a great gift to give your kids if you can do that. Because they can move through the world without neurosis, this anxiety about everything, which our own parents gave us.
I don't think I would have been great in the 17th century. I would have enjoyed the frocks, and certainly some of the food would have been appealing, but the disease and hygiene would have worried me.
A girl once came to my beery flat in Kensal Green, opened the blinds and cooked me breakfast. I married her.
I think the periods of being unsuccessful have made me a better actor.
The only time I've tried to make plans, the cosmic sledgehammer has intervened and something else has happened. You just have to wait and see what comes your way, so that's what I do.
Everywhere I go, I am The Doctor, and everyone smiles at me - they are pleased to see Doctor Who, who's far more exciting than I am.
Why can't jazz musicians just leave a melody alone?
My adolescence was a kind of motorway pile-up. I wish I had known that one day the geek would inherit the Earth.
I destroyed all my geek stuff because I didn't want to be a geek, and I regret it to this day. Consumed in the geek bonfire of the vanities was a collection of autographs and letters from Peter Cushing, Spike Milligan and Frankie Howerd, the first Doctor Whos, actual astronauts, and many more.
When I was a kid, I wrote to the BBC, and the producers sent me a huge package through the post with 'Doctor Who' scripts. I'd never even seen a script and couldn't believe that they actually wrote this stuff down. It sort of opened a door.
What you're doing is acting with yourself. Well, I'm my favourite actor, so in a way it's quite straightforward for me.
The nurses' job is emotional and distressing. Their day-to-day work is dealing with people withering and falling to pieces. So black humour is essential for them cope with that. It's just a consequence of their environment.
Hollywood producers aren't going to say, 'Get me that swearing, grey-haired, headless chicken. We need him for our new 'High School Musical' movie!'
