Well, congrats are in order to Paramount for slyly marketing its low-budget pick-up, Paranormal Activity, to bona fide box office success with $7.1 million on a mere 159 screens, with a wider release still to come.

But many of the fans savvy enough to seek it out are by now aware that Activity's ending wasn't always as it stands now. In fact, the film runs about ten minutes shorter between its late '07/early '08 festival screenings and its current cut.

So, to answer the questions that I and others fortunate enough to have seen the original version have been fielding, we'll be taking a look at as many differences as we can remember between the two, not to mention the further rumblings of what was different in test screenings for the film.

Naturally, this means spoilers. I know, it says as much right there in the headline, but for the sake of covering our butts, let's make this clear: a spoiler warning for everything that follows.

There, that ought to do it. Now click here for the full report at Horror Squad.
