Last Friday, a friend asked me if I wanted to go to a sold-out midnight advance screening of the reportedly terrifying movie “Paranormal Activity.” Since it was the very end of a long week, and I was sure I’d wind up asleep in my seat, and I said no. My friend said not to worry: If enough of the screenings sold out, the movie would be back in theaters later.

I didn’t have to wait long. “Paranormal Activity” is showing in Atlanta tonight at midnight, and there are show times throughout the day starting tomorrow. But it’s still not in wide release. For that to happen, a million people have to ask for the movie at its official site. So far, more than 666,000 have done so. It’s not really clear, though, whether the million-click goal is really a requirement or a guarantee — or whether it’s all just a stunt to get attention.
