I think '60s are appealing to creative people, because it seemed to be a time of endless possibilities, when the boundaries of what could be considered popular culture were being expanded almost by the week. It doesn't feel like that anymore. At times, I wish it were so. Radio is a perfect example; good God, I mean, back then the most interesting songs were also hits, and that's just not true anymore. It hasn't been true in a long time.

I'm in the process of working out an arrangement to make some very, very, very small films in the midst of all these films and maybe that will help. But you get tired of talking. You just want to do it.

Another thing that really excites me: I'd like to do multiple versions of the same film.

Once I had a potentially heart attack-inducing eight double espressos in one day. I think my assistant secretly swaps my coffees for decaf as she doesn't want me to die of caffeine overdose.

I'm mystified by the stuff that doesn't work. I'm mystified by what's going on in the critical side, too. Stuff I like is getting trashed and stuff that is being praised I think is terrible. I don't really feel in sync with what's happening, but at the same time, what I think keeps me afloat is that I try not to be, and don't want to be, very indulgent. I try to make the films as lean as possible, and to not spend a lot of time crawling up my own ass creatively.

The muscle memory of filtering away all the wrong versions of what you're doing improves the more time you're on a film set. I feel like my problem-solving algorithm got kicked up a notch.

If you're not smart enough to know what Fidel meant during the Cuban revolution, that - when they were on the Granma - Fidel was already a rock star in Cuba, and how important that was to the indigenous population, then you're not paying attention.
