As if everyone wasn’t already talking about the release of “The Twilight Saga: Eclipse” in theaters next week, even the trailers appearing beforehand are newsworthy. Among them is the highly-anticipated full trailer for another insanely popular book adaptation. The first official trailer for the first part of “Harry Potter and the Deathly Hallows” will run in front of prints of “Eclipse.” The trailer, which is different from the preview shown during the recent “MTV Movie Awards,” will premiere online on Monday, June 28th before being seen on the big screen beginning Wednesday, June 30th. Also rumored to be premiering in front of “Eclipse” is the teaser trailer for the sequel to last year’s horror hit, “Paranormal Activity.” According to Bloody Disgusting, sources say the first glimpse of “Paranormal Activity 2″ will preview before the new “Twilight” sequel. “Harry Potter and the Deathly Hallows” hits theaters on November 19th. “Paranormal Activity 2″ hits theaters on October 22nd.
