There's not a moment to waste in churning out another Paranormal Activity movie.  Who knows when you'll be able to find a free Saturday afternoon to make it?  Yesterday, we reported that Paramount would release Paranormal Activity 4 on October 19th.  Today, Bloody Disgusting reports that the studio has re-hired Paranormal Activity 3 directors Henry Joost and Ariel Schulman to helm the next installment of Ghosts n' Camcorders.  PA3 had the highest worldwide gross of the trilogy ($203 million) and came $4 million short of topping the original's domestic box office take of $107 million.  All of these movies cost the spare change found in the producers' sofas.
