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 enjoy things that are so far away from me; that's why, when I play things that are a little bit closer to me, I get really bored. When it's something that's the antithesis of what I am, there's much more to lose yourself in.
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 started doing the big Hollywood stuff, and I realised, 'Oh, there's no rehearsal at all; you just turn up on the set, and sometimes you haven't even met the other actor, or the woman who's playing your wife, and you're suddenly in bed with them.'
I got hooked to American news like a great TV season. It plays like fiction. I would come home from work, and I would put it on, and I would stay up until 2 in the morning watching it and get up in the morning and watch it.
I'd had a relationship with a French girl, a Japanese girl, an American girl, a Filippina and she was there all the time - a Lancashire girl. I thought: 'It's a Lancashire girl I was looking for. Why didn't I realize it?'
I don't worry. I'm more stoical. Of course I have insecurities. I fear getting older. I fear death and illness. I'm not prone to depression, but I get depressed because everybody gets depressed. Suddenly I'm away from my family or doing a job I'm not enjoying.
I see people around me with very unhappy love lives, who may have held out for that perfect somebody. And the failure to achieve that brings along a lot of bitterness which is very unattractive; therefore they're probably less likely to achieve it.
The thing about 'Harry Potter' is it's great fun because of the people - I was usually with Julie Walters and Mark Williams, Brendan Gleeson, Robbie Coltrane, and the kids. Wonderful, funny, amazing people. If you're going to hang around on a set bored, you might as well do it with Julie Walters.
When I'm sat in the pub with my mates, they've got their stories: Richard and Tracy have split up, they went to Arsenal and this fight broke out... My anecdotes are like, 'I was in this bar, and Michelle Pfeiffer rang, and I had wax in my ear, so I couldn't hear what she was saying...'
I think Varga is a manifestation, certainly, and someone who can thrive and profit from the world's failure and has worked out the operation, whatever the operation may be, that he's about, which will remain a mystery.
