You have to give credit to the people behind Paranormal Activity. The first film by Oren Peli became a word of mouth sensation, and they were smart to rush the second film into production to come out a year later. Now, just two years after the first film, they’ve already got a third film due out October 21. They’ve released a better trailer for it, and it already looks scarier than the second film. Check it out…

Though it appears this sequel could be called Paranormal Activity 3: Backstory, the trailer has more jump scares and spooky moments than all of the second film combined. The second film opened well, but it didn’t have the same impact or fun of the first film, it was also a weird prequel/sequel that told you many of the events happened before the first film so you knew it couldn’t go too far.

Here we’re fully into the backstory of the characters, but it already has a much creepier tone and feel. This may be due to directors Henry Joost and Ariel Schulman, the masterminds behind the documentary (or should that be “documentary”) Catfish. They also seemed to have a little bit longer of a time to get the sequel ready, as this was surely planned slightly before the release of Paranormal Activity 2.

And if you tweet about the movie, you can see it early. Check out the press release:

In an unprecedented move, Paramount Pictures will debut PARANORMAL ACTIVITY 3 exclusively in cities where the most fans “Tweet To See It First”. This first ever of its kind campaign launched today at 8:00 a.m. PDT and is open to fans worldwide. PARANORMAL ACTIVITY 3 will premiere on October 18th in the top 20 cities with the most tweets, 3 days before the film’s global release.

“The support of this franchise from the online community is phenomenal. We again look to reward them for that support by offering them the chance to see it first, this time expanding our reach globally,” said Rob Moore, Vice Chairman of Paramount Pictures.
