Couple of days ago, Warner Bros. released a teaser of the upcoming Batman v Superman: Dawn of Justice, a few months after the original trailer released. Today they released a second full length trailer that delves a lot deeper into the events of the movie. Here's a quick rundown of everything that happens. We see Clark Kent interact with Bruce Wayne for the first time, the former initially unaware of the latter's existence yet eventually it seems the two are well aware of who they are really talking to. We also see Jesse Eisenberg's Lex Luthor in action once again. Luthor in the movie seems nothing like what we have come to expect and has a totally different personality as was hinted in the previous trailer but made very clear now. The trailer also shows the fight between Batman and Superman in quick flashes, clearly not intent on spoiling the whole thing. The main about this trailer, however, is the introduction of Doomsday as the main antagonist. The movie shows him being created by Lex Luthor by experimenting on the body of General Zod, which is a departure from the original Doomsday story. We also see Wonder Woman's entry into the movie, which was saved for the last and was admittedly the best part of the trailer. The movie is set to release on March 25, 2016. Hopefully we will see more of Aquaman before...
