There was so much excitement revolving around the Batman V. Superman: Dawn of Justice trailer that was shown at the 2014 San Diego Comic-Con. Unfortunately it has never been officially released online. In fact, Warner Bros. said it was just for Comic-Con attendees. I’m sure a teaser of that will be released in theaters next year.
If you haven’t seen it, a Youtube user with the name ‘Free Will Revolution’ has recreated the trailer in animation so you can get a better idea of the footage shown at Comic-Con. I’d say he did an awesome job. Love the animation style – it reminds me of something out of Batman: Gotham Knight.
