The superheroes seen in “Batman v. Superman: Dawn of Justice” have been around for decades. A new series of photos shows how the costume of the caped crusader has evolved over the years and what Wonder Woman may look like in the movie.

Batman first appeared on screen in the 1940s, in black and white. This picture posted on the unofficial Facebook page of DC Cinematic Universe shows how the costume evolved over the years.

Perhaps the first color depiction of Bruce Wayne/Batman was seen in the 1960s ABC TV series. Over the years the costume of the character has taken on a darker shade and only the utility belt appears to stand out in terms of the color in some of the pictures.

The new costume of the caped crusader in “Batman v. Superman: Dawn of Justice” will be bringing back the gray color. The role will be played by Ben Affleck in the movie and his character will be taking on the Man of Steel, played by Henry Cavill. The two superheroes will be joined by Wonder Woman, played by Gal Gadot, for the first time on screen.

According to this post on Facebook, Cavill did not take any steroids in order to look muscular for the role and is also said to have refused to digital changes in the movie for some of the shirtless scenes. He supposedly felt that it would be “dishonest” to make such changes while playing Superman. The actor apparently relied on physical workouts to build his physique for the role.

This picture, also on Facebook, shows a set of promo images of Wonder Woman that some of the fans may have seen previously. The collection of promo art shows that the character will be wearing a cape and wielding a shield and a sword in “Batman v. Superman: Dawn of Justice.” The movie is slated to be released March 25, 2016 in the U.S.
