How do you avoid the curse of the Blair Witch? First, don't go into the woods around Burkittsville, Md., with a couple friends and a video camera. Second, don't make a rotten follow-up movie to a groundbreaking thriller. We won't know for about a month if Paranormal Activity 2 will be able to top the 2009 "found-footage" original, an indie gem that became one of the most profitable movies ever made. (Will the potential franchise be as dead as Micah? Oops—spoiler!) The first film has been compared to the still-legendary Blair Witch Project for its ability to scare the bejeezus out of audiences and rake in mounds of cash on a paltry investment. But everybody in entertainment and marketing knows how tough it is to catch lightning in a bottle twice. So far, all Paramount has had to do for the sequel's Oct. 22 debut is put out one trailer (above)—in front of this summer's hit The Twilight Saga: Eclipse—and one slightly enhanced version of the same snippet to set the blogosphere on fire. There are folks out there dissecting every nanosecond of this Easter-egg-dotted teaser. Is that Katie? Is that her (disappearing) baby? Is that a ghost voice talking backwards? The speculation is endless, and that has to be music to the studio's ears. Let's hope the product doesn't disappoint, but for now, even the pre-release chatter is fun.
