Man of Steel is one of the most anticipated movies of 2013 for comic book fans. At the Warner Bros. Comic-Con panel, the first Man of Steel trailer premiered. Zack Snyder and Henry Cavill also appeared to talk about the film. Comicbook.com was live at San Diego Comic-Con covering the event, and here are five secrets we learned. Superman Will Be Tougher – According to director Zack Snyder, Superman will be tougher in the Man of Steel. Of course, this comes as no surprise with the casting of Henry Cavill as Superman. In the past, Superman has always been portrayed as heroic, but he's had more of a nice guy image rather than a tough guy image. Cavill brings the tough guy image to the role. Man Of Steel Filming Complete – This news doesn't really come as any surprise, but it's good to hear it officially from the director that Man of Steel filming is done, and the movie is now in post-production. With a number of recent movies having their release dates pushed back, it's good to know that Man of Steel is own track to hit its June 14, 2013 release date. First Man Of Steel Trailer Before Dark Knight Rises – The Dark Knight Rises is also a Warner Bros. movie, so it makes sense that they would premiere the first full Man of Steel trailer in front of it. The Dark Knight Rises is likely to be one of the biggest blockbusters of this summer, so this is a great way for Warner Bros. to let a lot of people know that the Man of Steel is coming next summer. Superman In Trouble With The Law – In perhaps the most shocking scene from the preview footage, Superman appears wearing handcuffs, being led by a security force. As a super-powerful alien, could it be that local earth law enforcement has a problem with the Man of Steel? There is definitely a sense in the trailer that the world has turned against Superman. Of course, Superman could easily break out of handcuffs, but maybe he's trying to be a good citizen and go peacefully. Man Of Steel Will Have A Much Darker Look Than Previous Films – Zack Synder said the film is based on many different storylines from the comic books. Also, the look and feel of the Man of Steel will be much darker than previous Superman movies. It will have the look and feel of the type of films that Snyder usually does, but not with the exact feel as 300. Zod Is A Villain But Might Not Be The Main Villain – In the preview footage, there is a very quick flash of Zod, but Zack Snyder refused to admit that Zod will be the villain. About the villain, Synder teased, "Whoever he is he'll be super-relatable." Someone Else Knows Superman's Identity - During the teaser trailer, it was revealed that there is at least one person outside the Kent family that knows that Clark has some sort of powers. Apparently, someone saw Clark when he saved a bus of kids as a child. Superman Has A Beard – Superman is typically portrayed as clean shaven in the comic books, but he was sporting a beard in a scene in the Man of Steel trailer. Maybe, he's just copying Bruce Wayne's bearded look from a scene in The Dark Knight Rises. What is it with DC Comics heroes growing beards in their movies?
