The trailer for “Super 8” launched on Twitter. And now the movie will as well. Paramount announced today that J.J. Abrams’s Spielbergian monster movie will open Thursday, a day earlier than its scheduled midnight Friday release date, on about 300 screens around the country. In partnership with Twitter, the studio is directing people to #Super8Secret, a sponsored hashtag that takes Twitter users to a direct link to buy tickets for the Thursday screenings.
