David O. Russell's best films are thrilling high wire acts that run the moment to moment risk of tumbling to the ground. In his latest, "Joy," Russell has more trouble than usual keeping his balance on the wire.

And if you can come through that and still have some connection to your joy you felt when you were a child that's a very mature kind of a joy that I find inspiring. And Jennifer Lowrence has all that in her, and I've watched her have to go through it even in the last few years.

The whole trick is to make it feel like you're spying on real people's lives as they get through the day. When I'm writing, I have to trick myself as a writer. If I consciously say, 'I'm writing,' I feel all this pressure and somehow it doesn't feel as real as when it doesn't seem to count as much.

I was frustrated because I couldn't get going, as I was trying to figure out how to make films. I had various jobs, I taught a SAT class, I was a bartender, I had a day job at an office and was making short films.

The idea that anyone would think their religious ideas make them morally superior is just preposterous.

I think any spiritual experience that's worthwhile is not about ego and it will humble you in some way. And also, a Zen monk once said to me, 'If you're not laughing, then you're not getting it.'

The holy trifecta of directing and filmmaking is character emotion, camera movement and music. When you hit those three, that's magical. That's what I'm trying to do.
