When you make a film it is like asking yourself a question. When it is finished, you know the answer. Ultimately with all of cinema, we are just trying to learn about ourselves. I have always used the opportunity to make a film to learn more about myself, which I am still doing.

I wanted to be a film student again, as a man in my 60s. To go someplace alone and see what you can cook up, with non-existent budgets. I didn't want to be surrounded by comforts and colleagues, which you have when when you're a big time director. I wanted to write personal works.

Everyone knows the phenomenon of trying to hold your breath underwater - how at first it's alright and you can handle it, and then as it gets closer and closer to the time when you must breathe, how urgent the need becomes, the lust and the hunger to breathe. And then the panic sets in when you begin to think that you won't be able to breathe - and finally, when you take in air and the anxiety subsides...that's what it's like to be a vampire and need blood.

I'm very proud of my flops, as much as of my successes.

I remember in The Conversation, they brought all these coats to me, and they said: Do you want him to look like a detective, Humphrey Bogart? Do you want him to look like a blah blah blah. I didn't know, and said the theme is 'privacy' and chose the plastic coat you could see through. So knowing the theme helps you make a decision when you're not sure which way to go.

I always found the film world unpleasant. It's all about the schedule, and never really flew for me.

I've been offered lots of movies. There's always some actor who's doing a project and would like to have me do it.
