I'm fairly comfortable in fight sequences and stuff like that. I've done a few of them. I'm comfortable with that sort of stuff as long as I'm reasonably fit, and it's fun to do actually. I'm like a kid in a toy shop doing that stuff.
Recovering alcoholic guys wake up in the morning, and they have to think of a reason to get up, and then, once they're up, to not have a drink. It's like all these little heroic battles they have that they fight with and against every day of their lives.
I don't do my own stunts, but I do my own fighting. I don't consider fighting to be a stunt.
It's always fun to do the fight sequences and then to complete them, because some of them are quite complicated - with guns and so on - and there's always things that can go wrong. It's fun to shoot those things because we rehearse them very strenuously. It's fun to shoot them, and fun to know they're finished, that they're in the can so to speak.
Making a film, you do need stamina, whether you're doing fight scenes or not. It's important to keep fit. I'm not talking about having perfect abs and stuff, but you've got to be on top of your game, especially if you're playing the lead. You have to look after yourself.
