In many cases your imagination is much more effective than what can be shown. It primes you to know something is about to happen - the anticipation and anxiety is worse than what ends up happening.

It's always about finding the right balance between answering some questions and raising new ones to keep your story going.

In many places around the world, all over the U.S. and Europe there are active nuclear power plants. And for many years during the Cold War the threat of nuclear war was a permanent fear. There's always the concern that human kind is biting off more than they can chew in harnessing nuclear power.

For a found-footage-style movie, there's a definite advantage in using unknowns, because it helps sell the illusion that it's real. A known actor would get in the way of the suspension of disbelief.

Personally I like the slow burn; I don't think there is anything wrong with it. When I think about the movies that were most effective on me as a viewer I think of the original Haunting and the Exorcist, Rosemary's Baby, the Sixth Sense, the Others. These movies are not over the top at all, they are movies that rely on good story telling, good acting, good premise, good exposition and I want to stay true to that in future projects.

I'm pretty content with what I have, but the one thing that I don't have is something like the iPod - but PC-based. I think that would be cool.

Because of the way we let the actors improvise, it feels like you're watching people react rather than actors reading lines - so I think that's always going to be something I like.
