Warner Bros. has planned one of the most ambitious trailer launches in history for their upcoming Man of Steel sequel, Batman v Superman: Dawn of Justice. On Monday, April 20, fans can attend a special event at IMAX theaters around the country where the new Batman v Superman trailer will debut after a special introduction from director Zack Snyder. They spent this week teasing that big unveiling with previews of the preview on Snyder’s Twitter feed. This was a carefully orchestrated media event.
