I have worked for YouTube like texting and driving because I was curious to test what's out there and how does it function, can I release something like about texting and driving to very young audiences, at the age where they do their drivers test? And the response was phenomenal, millions of people saw it.

You are in a place that has not been seen for tens of thousands of years, because it was so sealed off. There is such silence that when you hold your breath you can hear your own heartbeat. Everything is so fresh that you have the sensation that the painters have merely retreated deeper into the dark and that they are looking at you.

I always had a feeling, for example, that there should be something from Verdi's "Requiem" in the film. You hear it when you see the lava flow in Iceland. That turned out to be a very easy choice.
