'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.

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

I've always had better luck learning things on my own. And I really love the challenge of doing it yourself and kind of being alone against the system.

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

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.

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.
