I'm sure I can make a movie that doesn't feel like a seventies movie! But the truth is, that's my favorite era in American filmmaking. To me, those were the great years.

People decided that I was the frat guy, even though I've never been inside a fraternity, or the guy who beat them up at school, even though that wasn't me at all.

One of the differences between now and then is that the idea of body image is a much bigger issue now. Back then, just being kind of heavy and barrel-chested passed for heroic. Now, you wouldn't dare to play a hero without a lot of dieting and various specialised abdomen machines. But that was one of the things which was interesting about it and I did want to portray because there's good and bad.

There's a lot of noise in the world, and the internet magnifies that energy.

I thought I could rely on the plot in the novel and fill in the colour between the lines, but I made a mistake with that assumption. It was really, really hard because you pull a few things apart and then you realise how everything relies on everything else and it can all fall apart.

(As) a director who is a writer, I have respect for writers, so I'm less likely to step on an idea or a line.

Anybody tells you that money is the root of all evil doesn't have any.
