I mean I've seen 3D films so far and I think it's a long way to go before they replace actors. It's a funny thing with 3D, I haven't quite got it yet. Yet.

The one piece of advice I would give to any actor is, if you want to go out on the street without being recognised, without even being looked at, go out with a 6ft 8in beautiful transsexual. No one gives you a second glance. Especially when you're 5ft 5in.

The sixth Harry Potter film - I don't like my performance in that film at all.

Because of the life I've had, I'd grown up quicker than most people.

I basically have the diet of a 19th-century Irish navy, apart from the litre of stout a day. It's meat and potatoes and bread and cheese: those are my four food groups.

I'm thrilled of the acceptance I get abroad. The people are so hearty, warm and grateful and I feel privileged having seen so many countries and some of the greatest monuments.

It's important to say that the more challenging a scene is, in a way, the more fun it is because the more of my job I get to do.
