Acting is art, but you should bring a healthy sense of irreverence in there and make it fun. When we did The Godfather there were a lot of jokes, a lot of laughs. We were mooning each other between takes! It keeps it loose.
Outside of work, just try to get through life as best you can. Me, I'm trying to get from the cradle to the grave without hurting too many people.
However well you do, it's good to have heroes. After I did Apostle I got a nice letter from Brando and I've got it on my wall. I think I like it more than my Oscar.
There's nothing like a good nap. I used to nap between takes when I worked, though now I like to go out and see what's going on. But during a regular day, take a nap.
If you dance a good tango it's not a meditative thing, but a quiet joy. It's not the passionate thing ? jumping around ? that people think. Let the music dictate what you do.
They say art's not competitive. It is; it's viciously competitive. But that just spurs me on.
Men are more romantic than women and they want to be in a union. Women can be more independent. I like being married ? and I've had plenty of experience. But you have to work at it, have a mutual respect.
You can have Sinatra, I'll take Merle Haggard.
The most interesting guy I ever met was the ex-soccer player Jimmy Johnstone, from Celtic. What a character: the voices, the rhythms, the speech patternsˇ¦ and he'd sing to me like Neil Diamond. He'd drink and come on to women. I named a dog after him.
You can have a certain life in this business that you can't have in others. My wife's 41 years younger than me, and when I first met her father he said: "I don't know whether to call you father or son." But it kind of works.
People think that they and I are the only ones who know I said "I love the smell of napalm in the morning". A lot of people have latched on to that saying. A preacher came up to me once and said: "I love the smell of gasoline in the morning." They can't all get it right.
I never read the critics. I just heard that the New York film critics didn't give anything for Crazy Heartˇ¦ zero. Jeff Bridges is wonderful in this movie. As far as I'm concerned, he should win the Oscar.
Soccer is boring for some people, but I love it. When Scotland play Brazil, one team think they're the best in the world, the other one know they're the best in the world.
I try and be a law unto myself, so that I can hopefully be impervious to outside things. People are critical of others no matter what you do. I try to be as good to people as I can.
Retiring is like the end of the world, especially in this business. You need self-fulfilment. Why retire? An athlete retires at 35, 40 at the most; an actor doesn't have to retire till he's 80 or whatever. A lot of people, when they retire, it's over, they're gone ? men quicker than women.
My wife always said a good meal and a good tango are enough to make you happy. She's right.
Crazy Heart is released on 19 February
