Last month, we reported that the long-awaited first trailer for Batman v Superman: Dawn of Justice will be attached to prints of Mad Max: Fury Road when it hits theaters on May 15. But that report claimed Warner Bros. may debut the footage online at an earlier date. Today, El Mayimbe reports that director Zack Snyder will release the first five seconds of the trailer through his Twitter page on Thursday, April 16 at 9 AM PT.
