Colin: There's something very basic about rubbing honey on your skin and going steaming with a bunch of strange Russian men.
Colin: I'm in no hurry to get anywhere. I don't have any plans. I don't have a map. If you did in this business, you'd destroy yourself
Colin: Ah, I know what the important things are in life. I know that, just because I pretend to be someone else for two hours doesn't make me a better person than the next man. So, I know those things. Simple things.
Colin: I'm fairly low-maintenance. Packet of smokes and a few pints and I'm a happy man.
Colin: I miss the people, the pubs, the canal, fish and chips - curry sauce on the side - cheese and nachos with jalapeno peppers in the UGC theaters in Tallaght. And I miss the seasons. I miss the grayness, the leaves on the ground. It could be a little bit more overcast in L.A. I find too much sun depressing.
Colin: I'm not really a rebel, but I take chances. I have a good time, and I live life the way I want to live it.
Colin: Being Irish is very much a part of who I am. I take it everywhere with me.
Colin: I'm just a true Irish boy at heart. I'm just myself, I stick by my guns and I treat people the way I think they should be treated, regardless of their status. And I just have a laugh.
Colin: I get no kicks from going to the gym. It doesn't do it for me. Never has. Some people enjoy working out. But that's never done it for me. In the past, I'd breathe in heavily between takes. I sucked it in and did a take. That way it doesn't hurt the beer consumption at all.
Colin: I go "You know what, who gives - who cares?" And if somebody does, that's their prerogative.
Colin: I have had an amazing 21/2 years, But if it all ends tomorrow, gawd, have I got stories for my friends and for my kids someday. And I've got it on film.
Colin: There was no time for long, meaningful pauses for the camera. My head was melted at the end of it. I had a great time. I smoked 120 cigarettes a day, I was a nervous wreck and I loved it.
Colin: I've given up a lot of things in my life and kissing strangers is one of them!
Colin: Maybe finding love is an impossibility. I've been lucky enough in my life to have been in love a few times. I've felt how wonderful it is and how hard it can be to be in love.
Colin: We took about two months of salsa lessons and it was fun, but I felt like a prick at the start. Of course, it was in a dance studio with mirrors everywhere to remind me of how much I looked like a prick not just felt like one. But anything that's not in the realm of your existence, helps you as an actor.
Colin (on his son, James): I have found a love that I never though I'd find through my son. It's a bizarre feeling to know that nothing can come between us.
Colin: I still think I'm Peter Pan. I still don't want to grow up, so I'd never say anything is for good, but I have a newfound appreciation for life. Not that I was suicidal, but I never had that much of a will to live a long life, although there were plenty of reasons: my two sisters, my brother, my mother, my friends, my work. I had just decided not to look at them. But now, through the birth and existence of my son, I want to be alive for a long time and watch him grow up, be his best friend and his father, and hang around with him. He is the greatest priority in my life.
Colin: I haven't had a drink in six months, so I'm certainly not going out drinking 'till five in the morning now. It just caught up with me. I got my arse handed to me on a plate. It was a long time coming.
Colin: Love sounds like a beautiful idea, but it comes with a lot of responsibility and a lot of pressures. It's kind of better for me right now, for whatever reason at 30, to be on my own. But sure, some day it would be nice, if I met the right person…
Colin: I took some time off after Miami Vice, for the first time in six or seven years. I got to step back and have a look at what I've been through, at the life that I've created and where I want to go. It was a metaphorical deep breath. I needed it.
