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.

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.

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 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.'

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