Batman v Superman: Dawn of Justice trailer has reportedly leaked online before its intended reveal at the San Diego Comic Con 2014.

KDramaStars claims that news of the eagerly-awaited teaser getting leaked online was reported by Comic Central City. Although no video of this alleged teaser can be found, a detailed description of the clip was posted on the website:

"The Batman vs Superman trailer starts with a dark screen with the voice over of General Zod's 'you are not alone message' [from Man of Steel]. The screen slowly pans and it reveals that the scene is inside the Batcave. The camera slowly pans to a shot where you can only see the back of Batman but he is not yet wearing his cowl. Every monitor in the Batcave is playing Zod's video. After the message is complete, Batman wears his cowl turns to the camera and the trailer ends with the Batman v Superman: Dawn of Justice logo being revealed."

We know that director Zack Snyder has shot certain portions with Ben Affleck in the new Batman suit. It remains to be seen whether this description really fits the rumoured trailer reveal at the San Diego Comic Con (SDCC).

Reportedly, DC Comics and Warner Bros are going to put on a good panel for the fans at SDCC by showing the Batman v Superman: Dawn of Justice teaser trailer and announcing their line-up of superhero films for the next four years.
