I mean, on my films I try to shoot as much in camera as possible. On Interstellar, my last film, for example, we didn't use any green screens. So when we were shooting inside a spaceship, we had views outside the windows. We produced all that material and we shot at a chief effect in camera. And when you're asking... Even a bit where Matthew McConaughey's tumbling through us, sort of space-time continuing with that indeed is what he's doing. Indeed, we built a set for that. And we enhanced it with visual effects. And visual effects technology has been wonderful for enhancing those things and increasing the vocabulary. But sometimes when you're asked to justify these things, like not using green screen, you have to just bring it down to... Well, it's so much more fun to do. It's fun for the actors, it's fun for me. There's nothing more disparaging than when you turn up the work and there's just a green screen with a couple actors in front of it. It's really the magic's not there. So do you miss any of the gags from the old TV series? Do you think you've hit the right gag quotient in those films? I think you put as much humor in as the tone of what you're doing will sustain. And we were very fortunate to have Michael Cain, you know, along for the right to drop the odd... The odd gong. Funny lie, the odd bit of heart, and also Morgan Freeman. You know, I've had some wonderful actors in there, but those guys, particularly, they let a degree of warmth to something that otherwise could be too dark, too cold. Are you Tony Stank?
