The Americans take a product that literally grows on trees and turn it into a valuable commodity. Without them, cocaine and marijuana would be like oranges, and instead of making billions smuggling it, I’d be making pennies doing stoop labor in some California field, picking it.

Shane Salerno and I adapted my book Savages together, and I learned a lot about adaptation. I think it's an extremely difficult thing to do; adaptation might even be more difficult than writing an original screenplay. It's so much a matter of choices, making choices of what to leave in. It was an education.

I think people will be surprised at some of the things about the shootings by policemen of unarmed African-American men. But I also think it's a balanced view. Balance has become almost a dirty word these days. It seems we're supposed to pick one side or the other. But these issues are extremely complicated. I think people will be surprised at some of that.

My grandmother was from Guelph, Ont. I grew up playing ice hockey, I'm a massive fan. A great-uncle who was in the early days of the NHL played for the Chicago Blackhawks.

With a 660-page book, you don't read every sentence aloud. I am terrified for the poor guy doing the audio book. But I do because I think we hear them aloud even if it's not an audio book. The other goofy thing I do is I examine the shape of the words but not the words themselves. Then I ask myself, "Does it look like what it is?" If it's a sequence where I want to grab the reader and not let the reader go then it needs to look dense. But at times I want the reader to focus on a certain word or a certain image and pause there.

I was researching some of the modern-day figures that The Sopranos were moulded on. So many iconic Sopranos moments. James Gandolfini and Edie Falco had an incredible scene together in the kitchen of that house that looked like it was about to explode. That was an iconic series that changed the way we did television. It is also an extremely realistic portrayal of the mafia. Much more so than The Godfather. The Godfather, one of the greatest films ever, but let's face it, a romanticized version of the mob.

A lot of times, writers are told write as big as you can, and that's not untrue. But at times I think it's better to write as small as you can, to start scenes with little personal details or people who are doing average every day human things. That, to me, lets the average reader into that person's life. "Yeah I eat breakfast. I take a shower."
