The making of 'Naked' was an absolutely phenomenal, mind-bending experience. That film was life-changing and put my career onto a whole different level.
That's one of the main things I've learned: honesty is paramount. The biggest thing I try and instil in my daughter. My deepest regrets have been to do with times that I've been dishonest. There's nothing worse than getting caught out in a lie. It's excruciatingly embarrassing.
It's not the easiest thing to have two actors in a family.
I can remember, after I started doing films, my mum began going to more arthouse films. She went to see 'Edward Scissorhands' and phoned me up and said: 'What was that all about? He had scissors on his hands.' Good question. I think she should review films on Channel 4.
I don't think they should trust anything that happens in 'Fargo' at all, and I'm sure 'Fargo' fans know not to make the mistake of trusting too much.
I often do that with characters, going back to my bloody drama-school days, in terms of equating them with creatures. And it's very much there as a theme of all the seasons of 'Fargo' as well: the predator and the prey.
I wanted to do 'Fargo' rather than do a TV production. I've been offered TV things over the years, but usually, that's about that I don't want to be away from home for that long because it's a long time to be away your home country and my family.
I could, of course, have written about the film world and the jealousy there and the frequent belief that others don't have talent. But, for some reason, it just struck me to write about art.
'Naked' kind of kicked me off into the film world. It just so happens that all of the things that I have been offered have been films, and I've enjoyed the travel that goes along with that.
Playing a character who becomes a Buddhist was a great experience.
'Harry Potter' is very nice because it's very easy to make children happy. All you have to do is have your photograph taken with them.
It was so boring, and 'Dragonheart' was so unchallenging - there was no research involved or any rehearsal. So I was in my hotel room every night with no English-language TV except 'Beavis and Butt-head' at 10 o'clock every night.
One can only improvise what one knows.
I paint a bit myself. My house in Clerkenwell has a room that is done up like a big installation.
I often draw from people in my own experience to base a character on, going back to my days with Mike Leigh.
I've always tended to write comedy, but I'd hate to just write some kind of sitcom or a lighthearted series of jokes and slapstick. I wanted to talk about some deeper things within the comedy.
I am the sort of guy who does go to modern art shows.
You can't actually be just a movie actor in Britain, because we don't make that many movies.
Publishing a novel was such a proud thing for me. When I was a kid, I used to say to my mum and dad, 'I'm going to write a book. You'll see.' So when I did ,and it was published, and people liked it, it was great.
It wasn't a good idea to work on 'Naked' in the first months of a marriage. I was living apart from my wife in a flat overflowing with books I was reading for the part.
