The Empire on W. 42nd Street in Manhattan has sold out all of tonight’s added screenings of “Paranormal Activity,” which if you believe the movie’s website will not be showing again until Thursday night/Friday morning at midnight. But if you follow the site’s link to movietickets.com and type in the zip code 10019, you will discover tickets being sold for 10 p.m. screenings at the Empire on Sunday through Thursday nights. As we noted yesterday, the L.A. Times is reporting “Paranormal” will be showing at all hours  in around 60 cities, including The Big Apple, starting next Friday.
