With great word of mouth that has seen Paranormal Activity growing from being a movie that was nearly not released at all (the original plan was for Paramount to buy the film just so they could remake it), the film is now the breakout hit of the year in the US. It made $20 million last weekend, and is on track to be the new Blair Witch Project. The mockumentary is composed of footage supposedly shot by a couple in their own home, which is being blighted by weird, supernatural occurences. The movie isn’t due out in the UK until November 27th, but a new US trailer has emerged, so if you’d like to know a little bit more about the hit microbudget thriller, click below.
