I've only post LCOZ mentions, link to full interview at bottom.

Before things wrap up here, very quick: Lost City of Z is as close as we’re hearing?

Z? Yes, absolutely. I’ve been on a scout. Pre-production should start sometime in the first week of June. I’m extremely excited about it. It’s very different from anything I’ve done — and yet, of course, the same. I have very, very high hopes for it. Principal photography, I believe, will start on August 8, although it depends on when Charlie Hunnam will finish King Arthur, which is what he’s doing now; if that finishes on schedule, that’s when I will begin. It shoots in the U.K. and Columbia, probably.

What feeling do you have when on the cusp of starting a production? Is there a lot of anxiety, or is it mostly pure anticipation?

Well, it’s almost exclusively terror. It’s funny: I don’t actually derive much pleasure from making a movie. I derive a lot of pleasure from having made a film. I’m very excited; it’s going to be a huge challenge. But I’m very scared, and I’m under no illusions that I’m going to go to the jungle and have a great time and it’s going to have a party. I mean, it’s going to be an epic struggle, and I’m going to try and do my very best. I have many, many ideas. The project’s been gestating for a long time, and, in some respects, that’s a challenge in and of itself, because you have many, many ideas, and you want to make sure the project has a unity and a singularity and a uniqueness and a consistency. So, if it’s gestating for a long time, you worry that you won’t have that.

Well, we’ll see. But, judging by your track record, I’m not too worried.

I’m glad you’re not.
