A teaser trailer of Batman v Superman: Dawn of Justice has reportedly leaked online, and going by reports, it seems like fans wanted the trailer to be Batman-focused, which it is.
According to Moviepilot, the trailer has been leaked on the internet and revealed on 4chan.
Check out the description of this teaser below: (via Moviepilot)
The trailer opens to the Man of Steel ending during the chaos and destruction in Metropolis as Ben Affleck narrates something along the lines of, "...the world has changed with the arrival of the Kryptonians."
Cut to Affleck in his Batsuit and he asks whether Superman is here to save us... Or destroy us? Before revealing..."I'm going to find out"
At which point...we cut to a shot of the Batman v Superman logo.
As per the website, the hard-to-find leaked trailer is "floating around the web and very few people have actually seen it."
So maybe this is just one of the many rumours about the first trailer of Batman v Superman, or it could be the real thing. That remains to be seen.
However, if the trailer did actually leak online then maybe the people at Warner Bros immediately got to work and pulled it off the web - the way they did for the leaked comic con trailer.
