At the Sex Institute in Bloomington, Indiana, they were a phenomenal help, too. We went out there for a few days, and they gave us access to materials. And the biographies, there are four or five, ranging from very poor to excellent.

And as the hour approached for the execution, in his own mind, Collins became both the executioner and the victim. He would pace up and down, transformed in almost a kind of exorcism when he knew he was responsible for taking someone's life.

And the Institute sent me a little film footage of Kinsey himself preparing to do an interview for television to talk about his work, so that was quite valuable for me.

Well, I think I've made 44 films and only like four times I've played real characters I'm just drawn to people who have a pioneer spirit, this extraordinary energy and commitment to their cause.

Well I think people think sex is controversial. Not always, but certainly it's something to be discussed.

Well, I think they're all basically the same story. Every culture in the world has them. When you strip it down and analyze it, it's the young man or girl who goes through a trial or ordeal and hits a very low ebb but manages to get guidance from a Merlin type figure.

I'd like to play Ian Paisley, actually. I'd need building up, though he's very frail now.

I always wanted to be a cowboy, and Jedi Knights are basically cowboys in space, right?

But, you know, sex is controversial, it just is and it always will be.

Getting married and settling down isn't the most important thing in my life.

Sitting down to eat in our house is about sharing, you know, talking about the day you've had, be it in school or work or whatever, so that's very important to us.

Acting is invigorating. But I don't analyse it too much. It's like a dog smelling where it's going to do its toilet in the morning.

In bed at night, I could be reading some book, and I'll come across a sentence that's totally unrelated to some scene I did years ago. But I'll play the scene back in my mind and think, I did that wrong - I should've opened the door more slowly.

At the Sex Institute in Bloomington, Indiana, they were a phenomenal help, too. We went out there for a few days, and they gave us access to materials. And the biographies, there are four or five, ranging from very poor to excellent.

I love working with children and this young boy, Thomas Sangster, is quite a remarkable young actor. He raises your game, you know. He certainly raised mine.

But I was very, very lucky, and it was a wake up call as far as motorbikes are concerned. I never flirted with death on the bike, but now I'm totally convinced they're death machines.

Well I was on the jury duty on the Deauville Film Festival, a few years ago.

It's extraordinary to look into a baby's face and see a piece of your flesh and your spirit. It makes you realize you are a part of the human race.

It's interesting, the more successful you become the more people want to give you stuff for nothing.

I thought, well of course, Kinsey absolutely adored teaching. He was a wonderful teacher. So these kids really inspired me. So that was a clue I hung onto. He loved young people, he absolutely loved them. And he loved teaching them and trying to help them.

But let's just say, I'm Irish. I grew up in the 1950s. Religion had a very tight iron fist.

Acting with creatures that aren't there is kind like acting with an actor who refuses to come out of his trailer. You still have to go on and do the scene.

Kinsey's quest was really for us all to be tolerant and accepting of each other.

Every cliche about kids is true; they grow up so quickly, you blink and they're gone, and you have to spend the time with them now. But that's a joy.

I'm not the kind of actor that would know what my character had for breakfast last Tuesday.

Well, from an acting point of view, I bear no relation, I don't look like Alfred Kinsey at all, but I thought somewhere in my artist's soul, my actor's soul, I could capture something of the spirit of the man.

Yeah, well, I finally stopped smoking for good.

People ask me if I ever feel outside the Hollywood loop, and I never do, because both of us do a lot of theatre, so it's great for New York and it's also half-way between Europe and the west coast, so it's the best of both worlds.

I did, although I didn't read from page 1 to page 187 but I read chunks of it. I did a little bit of science when I was in the university so I was able to understand the graphs and pie charts and stuff like that. It was extremely dry.

In Los Angeles, it's like they jog for two hours a day and then they think they're morally right. That's when you want to choke people, you know?

Some mornings you wake up and think, gee I look handsome today. Other days I think, what am I doing in the movies? I wanna go back to Ireland and drive a forklift.

Yes, I'm Catholic; I'm proud of it. But I had lots of Protestant friends.

But, you know, there's still an argument, there's still ten states that outlaw premarital sex, and many more states where adultery is still outlawed and a crime.

A sex symbol? A symbol of sex? I don't think that I am a sex symbol, although it's very flattering. I'm 59, now, so I think I'm possibly past my sell-by date. I think I am.

As you know, Hollywood loves to pigeonhole all the actors and actresses, and suddenly I got 're-pigeonholed' as an action actor.

For every successful actor or actress, there are countless numbers who don't make it. The name of the game is rejection. You go to an audition and you're told you're too tall or you're too Irish or your nose is not quite right. You're rejected for your education, you're rejected for this or that and it's really tough.

Hollywood is throwing action movies at me.

I came to water late. I learned to swim at the age of 20.

I don't do my own stunts, but I do my own fighting. I don't consider fighting to be a stunt.

I don't know if I'm a strict parent or a pushover.

I don't think I'm funny.

I get fed up with plots that are driven by someone constantly getting information on a computer.

I had done some flimflam movies, but I didn't understand what being an actor meant anymore.

I have friends who have daughters and there's times I think I'm glad I have boys instead of girls.

I have no desire to play King Lear or Hamlet. I never had a grand ambition. I just followed my nose.

I have often found that no matter where I meet people in the world, there is a path that leads back to Queen's.

I have to make it my job to be careful with my family.

I keep fit as much as I can.

I love doing my own stunts but it's hard.
