My mother taught me what it is to have a sense of humour; my dad, who was a headmaster, everything you need to know about hard work. My dad is the most decent man you could come across.Collection: Dad
In my life, I have made the occasional catastrophic choice, and it's just a case of moving on and learning from it.Collection: Moving
People love watching medical dramas - they also love watching documentaries about the workings of the brain.Collection: Medical
Belfast is a city which, while not forgetting its past, is living comfortably with its present and looking forward to its future.
My best friends are still the ones I first attached myself to when I went to school because, all of a sudden, I was leaving the rather pampered and occasionally very annoying world of having three older sisters to go to a male-dominated world.
Ours was a very progressive Protestant family, but my parents were God-loving rather than God-fearing. We went to church, and I still go with my mum and dad when I return home - it's a family thing. I played flute in my dad's marching band, but I had an integrated upbringing. We had a lot of Catholic friends.
I feel old and vulnerable. I now realise that I knew nothing and know nothing, but back when my career was beginning, I thought I was a man when, in fact, I was a dewy-eyed boy who'd not seen an avocado or eaten a tomato.
When I was at drama school, I was totally broke, and a lot of my mates had jobs and were financially very good to me, so if, for example, I take them away on a trip to a football match in Europe, it means that I can pay them back a bit.
A lot of people of my Ulster Protestant background would have been very suspicious of the notion of a film about Bloody Sunday. Our fear would have been that it would be terribly anti-Britain and anti-soldiers: a piece of nationalist propaganda.
Before I read the 'Bloody Sunday' script, I have to admit I hadn't thought about it that much. There was probably even part of me which assumed there was no smoke without fire. That the Catholics who were shot must have done something to provoke such a response from the army. I was extremely ignorant of the whole situation.
Like the character I played in 'Jekyll', we all have different masks we put on for different occasions. As much as we all want to lead decent lives, we're also attracted by the idea that something dark may lurk within us.
Several years ago, I began losing my hair, and like a lot of men, it was a major concern to me, in fact it was practically an obsession. But, also I'm an actor, so I'm in the public eye a lot and I really felt that my hair loss could affect my career prospects.
I'm not strong-willed enough or unkind enough... or maybe simply not wise enough to tell a journalist that a subject is out of bounds.
The thing to remember is that the work comes first, and not to get distracted by anything else. If you keep focused on the work, everything else will fall into place. That's my mantra now.
Funnily enough, Northern Ireland is a great example of where politics can win over conflict. The decision to down arms and follow a political path would have been unthinkable once. It shows just what is possible.
I was one of the many kids in Northern Ireland who grew up in the countryside and had an idyllic childhood well away from the Troubles.
I didn't much like Las Vegas. The noise of the place and the whole 24-hour, 'let's play the slot machines all night' culture of the place just left me cold.
There will only ever be 13 dwarves in 'The Hobbit' - and I was one of them. If I had my time again, would I do it? Yeah, I would.
When you suddenly become successful, the change is enormous, both financially and in terms of recognition and the way people treat you. I found that hard to deal with. I got very guilty about it, and I think I put up obstacles to prevent myself enjoying it.
As I told Piers Morgan, 'Catholics have confession, whereas Northern Irish Protestants only have interviews.'
I don't know a single person who doesn't regret the things that they did to hurt their parents, or the things they didn't say to them.
I'm increasingly realising our consciousness and subconsciousness are extremely different, and our subconsciousness motivates us, but so far, I don't know what drove or motivates me.
I grew up loving women and without misogyny, rancour or prejudice, totally loved and loving. And no matter what has happened since, I don't think I have treated women in my life very badly.
Because I grew up with women, I have a certain amount of charm, and I'm all right to get on with, kind enough, funny enough, blah blah blah.
It's a complicated relationship with the place one grows up in, particularly if it's Northern Ireland.
Theatres, along with the likes of the Ulster Orchestra, for example, are the cultural heartbeats of our towns and cities, and without them, we are much poorer for it.
If you are going to tell a story about a child going missing, it's going to have similarities with a real life child going missing.
I've never thought of myself as a classic leading man. I'm a character actor who happens to play leading roles. Come on, look at me. I'm really Desperate Dan.
Brain surgery is a fairly aggressive process. There's a lot to get through. There's the beautiful, delicate shaving first, which is really lovely. There's a wonderful ceremony of putting all the covers on, so only the little bit you're operating on is revealed. But once they make the incision and tear the skin back, the drill comes out.
Actually, I played Pontius Pilate as nice. An actor spends his life thinking he is Christ, and then he gets to play the character that killed him.
Perhaps not being very self-aware in the past masked depression. I think I was confused. I think I was immature. I think I probably was quite depressed.
Richard Armitage is very good at the old horse riding because of course he did it in 'Robin Hood,' so he's very good at that.
I think often there is great rivalry between neurosurgeons and cardiac surgeons. I think I maybe have a bit of bias with neurosurgeons' opinion that nothing tops neurosurgery! But that makes for a quite interesting conflict between the two.
My early ambitions were the same as they are now - to play for Manchester United. I was, and still am, football mad.
