By trade, I am a software programmer, so I never really had any experience with movies before. I started out with 'Paranormal Activity.'

The less people know about 'Paranormal Activity,' the more they enjoy it.

'Paranormal Activity' was a unique project in that I made it basically on my own, with a little help, and I had no exposure to the filmmaking world when I made it.

Even if you look at the 'Paranormal Activity' movies, at the end of the movie things get really crazy and nutty, but they all start in a very mundane situation that people can relate to, and that's also to some degree what we tried to do in 'Chernobyl Diaries.'

I'm just considering myself extremely lucky. All I wanted is to have 'Paranormal Activity' be released and become successful. And everything that's happened since then is just an enormous bonus.

Even when I was making the first 'Paranormal Activity,' I didn't tell anyone I was making it, not my friends or neighbors or co-workers. I just kind of found that there was nothing to gain by announcing to the world that you're doing something.
