All the animals come out at night.

When you have people who are embarrassing themselves for a living, who are making themselves look foolish and vulnerable and emotional for a living, your day-to-day reality is going to be a high-wire act. People are going to get in fights. People are going to get upset. People are going to walk off set. People are going to call each other names. It happens on every film that has any emotional people.

The secret of the creative life is how to feel at ease with your own embarrassment. We're all in the dirty laundry business and we're being paid to take risks and look silly. Race car drivers get paid to risk their lives in a more concrete way; we get paid to risk our lives in an emotional way.

The clock is impotent; mechanical time does not affect those living in an eternal present.

'Taxi Driver' wasn't autobiographical in terms of the actual events, but I did draw on my own mental state.

I had this whole issue of doing a crime film in the 2010s. The genre's been mined very, very heavily. Post-Scorsese, post-Tarantino, post-Guy Ritchie, what do you do? I wasn't attracted to pulp so much as all of a sudden I had a pulp problem. I had to find a way to make this interesting, because there's a lot of crime films that come out on VOD every week, and a number of these star Nicolas Cage.

I could be just a writer very easily. I am not a writer. I am a screenwriter, which is half a filmmaker... But it is not an art form, because screenplays are not works of art. They are invitations to others to collaborate on a work of art.
