Everything's borne out of human experience, of course - rejection, humiliation, poverty, whatever. People aren't born bad, no matter how harsh the circumstances. There is a person in there, and that person is not made of ice.
Every couple of years - no, that's every couple of weeks - I think I'm going to give up acting.
For me, now, working and children is it. There's nothing more to life.
So-called reality TV, which dominates British channels, is destroying what made it cherishable to me and lots of others in the first place. I loved Alan Clarke, Ken Loach and Alan Bleasdale's work. In fact the first TV dramas I ever saw were 'Screen Twos' produced by David Thompson, who also produced a lot of Alan Clarke.
I have Googled myself, yeah, I think everybody has. I try not to make a habit of it - in fact I made a rule once never to Google myself, which made me happy.
There was a year between school and getting going as an actor when I basically just watched films. Video shops were the new thing, and there was a good one round the corner and me and my brother just watched everything, from the horror to the European art-house.
The first time I played a killer, in the 1997 film 'Mojo,' I went to my local video shop and got out a video of real executions and a history of the Third Reich. The guy in the shop was giving me a look. I thought this would help, but I don't think it made any difference, and I don't want to see any more executions.
I have been in control of what I've been doing, of the career I've put together.
It's always more interesting to take on someone that's going to have hidden sides or a fatal flaw, because there's going to be more to play with - more conflict, internally or in and around them - but it's probably the thing of finding the positive in there.
I heat myself up over the fact that I am never going to be as good as I want to be.
My own rapping skills are quite good, actually. You get this thing, I think it's called Songify or AutoRap, and you talk into them, and they auto-tune it and make it into a quite interesting musical number. And I got one where it builds it into a rap.
I hate it when people tell you you're good when you know that you're not.
'Heroes', 'Desperate Housewives', 'The Sopranos' - they're all very stylised. 'The Wire' is much more rooted in realism and honesty. In American television, I can't think of anything I'd rather have been in because it has got something to say and that is the kind of thing I want to do.
To start, I wasn't really interested in acting at all, and I didn't make much impact. The first play I was in was on for five nights and I didn't show up for two of them and nobody noticed. But I stayed because that's where my friends were, and after a while I found myself wanting to inhabit other people's worlds and lives.
I don't really differentiate between different genres: if there's a good part going, I'll go after it, and it's preferable to me if it's something I haven't done before.
I do what I can, but I'll always give it a shot. You're not going to see me playing a Welsh character any time soon, not because I wouldn't love to. I went up to Wales once and read for a film with Rhys Ifans, and haven't been asked back since. We did have a nice time on the train on the way back.
I've made a point of trying not to play the same part, and of moving between theatre and film and TV. The idea is that by the time you come back, you have been away for a year and people have forgotten you. If you like having time off, which I do, that's a good career strategy.
I didn't want to go to college or work in an office or have a nine-to-five job. I knew that quite clearly before I left school.
It seems to me that most characters, in anything, are flawed in some way, just like most people. You look for the good in the flawed people and vice versa, and then try and make them appealing in some way.
I'd quite like to do a musical. I'd probably have to develop that myself.
