It's not so much what you learn about Mumbai, it's what you learn about yourself, really. It's a funny old hippie thing, but it's true as well. You find out a lot about yourself and your tolerance, and about your inclusiveness.

You live your life and it ends quite quickly and all you can do with it is pass it on decently to someone else. Whether directly or indirectly, behave decently to other people.

Actors are steeped in a world of agents and where the next job is coming from and what are their expenses and what is the hotel like. You want to take them out of that world and dump them into another world, so that when you meet them on the screen they don't seem like the guy who was in two others movies that year.

I love that sense of change that you'd get in pop music every three minutes, every four minutes.

I dont see much difference between it and the other films though I can see on a rational and intelligent level there is a big difference.

To create the reality of space with this sense of suspension: nothing's happening, it's endless; we're traveling at 28,000 kilometers an hour but nothing's happening. Nothing! And you have to do that! There are all these rules you have to follow, I've never known anything like it.

Your first film is always your best film, in a way. There's something about your first film that you never ever get back to, but you should always try. It's that slight sense of not knowing what you're doing, because the technical skills you learn - especially if you have a film that works, that has some kind of success - are beguiling. The temptation is to use them again, and they're not necessarily good storytelling techniques.
