"Man of Steel," starring Henry Cavill and Amy Adams, hit theaters in June. The film has grossed over $630 million worldwide, thus far.
This team-up comes shortly after Warner Bros. and DC Comics released the direct-to-video two-part DVD, "The Dark Knight Returns," starring Peter Weller and Ariel Winter. The film was based on the classic Frank Miller mini-series by the same name. In that film, Superman and Batman were at odds.
It's unclear what the plotline or title of the new film will be. It is also unclear who will play Batman, as Christian Bale, the last to do so, has said he would not appear in any other films.
In addition to that announcements, which was confirmed by Warner Bros. it's been rumored that there are "tentative plans for a Flash movie appearing in 2016 and a Justice League movie in 2017." With today's special effect, we'd assume that The Flash, DC's Scarlet Speedster, will no longer be relegated to speeds of about 60-100 MPH.
Starting in 1954, DC Comics debuted a long-running comic book called "World's Finest," teaming Batman and Robin and Superman. However, as times progressed, the pair became more antagonistic, with Superman disagreeing with Batman's dark style.
However, the climax of "Man of Steel" may mean that the pair are not so different, after all.
