One of the more interesting rumors regarding Zack Snyder's "Batman v Superman: Dawn of Justice" has emerged over at Bad Ass Digest in recent days.
According to their sources, 'Dawn' will have setup a world in which Batman has existed in the world of Gotham for around three decades with Bruce Wayne (Ben Affleck) now in his fifties. Batman himself is still an urban legend with no picture ever having been taken of the vigilante in action.
The Dark Knight is a 'quiet operator' who has never been involved in a massive battle, instead waging small vigilante crusades. Yet he's had adventures over the years, and the Batcave includes a memorial containing a "war torn Robin uniform".
They also say Wonder Woman has existed for some time as well when the movie opens, her activities and wild adventures just as secretive as Wayne's. Yet they've also but "in a very different, and unexpected, way".
