It’s being called the “scariest movie of the decade” and the next “Blair Witch Project.” Which means it was shot on the cheap ($11,000 to be precise.)

Paramount bought this film years ago and always intended to remake it with fancy budgets and professional actors. Apparently the film tested so well with audiences though that they just decided to release it as is.

The trailer doesn’t give much of the plot away. Only that you will probably leave the theater relieved and slightly nauseous.

Paranormal Activity will be released to theaters on September 25, 2009.
