You could make an analogy to a security guard who, three weeks prior, was mowing lawns for a living. The second he puts a uniform on and that badge, he's a man. I imagine the majority of us have felt the wrath of the over-zealous security guard guy. Is there something lying dormant in the man, that's waiting to be pumped up with that kind of power? I don't know. Does it reveal him? I don't know. Does it change him? I don't know.

You gotta be careful: don't say a word to nobody about nothing anytime ever.

People in life, when they have a tendency to exaggerate or lie or whatever, you always sort of notice that their voice goes up quite high.

When you take on the idea of playing someone like Jimmy Bulger, it's a radically different process because you're going into make-up. The only way you can do it is to come out of make-up looking like the guy. If you don't look like the guy, it's going to bug you, all day.

With every character you play, as these guys will tell you, there's a part of you goes into that in terms of the ingredients of making this stew. There's most definitely a part of me in Captain Jack and now, fortunately or unfortunately, there's a great part of Captain Jack in me as well. Basically, I can't shake him. He won't leave me alone. He just sort of keeps showing up at odd times.

Trips to the dentist - I like to postpone that kind of thing.

After having been confined to a television series - and it's a luxury job - where you can't play anything but one particular character for nine months out of the year, it will make you insane. It didn't affect me. I got out quick enough.
