Sony Screen Gems has made some major changes in their forthcoming genre slate. Let’s start with the highly anticipated Underworld 4, which is said to no longer be arriving in 3-D. The vampires vs werewolves action-saga will arrive in theaters on September 23, 2011. This is a major delay from the originally announced Jan ’11 date. Scott Charles Stewart’s follow-up to Legion, Priest, will now be arriving in cinemas on January 14, 2011 – shifting from its original August ’10 date – and is also said to be converting to 3-D. Lastly, The Roommate is being pushed out of its September slot all the way back to February 4, 2011. So while 2010 will be a quiet year from Screen Gems, 2011 is set to explode.
