One of the scoops at San Diego Comic-Con this year was that, in the sequel to Man of Steel, Superman would be pitted against Batman, bringing to mind their battle in The Dark Knight Returns.
There is already much speculation as to how the movie will be plotted. Zap2it.com Contributing Editor Billy Nilles calls the premise a bad idea, asserting that writer David Goyer and directer Zack Snyder have "irreparably altered Superman's philosophy".
While I also found Man of Steel's final battle clumsily contrived, the rationale behind the sequel may be as simple as profit. Thanks to Tim Burton, Bruce Timm, and Christopher Nolan, Batman is probably Warner Bros.' most lucrative property. Meanwhile, though Superman hasn't been as successful at the movies, he remains popular enough to have afforded TV's Smallville ten seasons. Regardless who plays Batman or how problematic the plot, people will go see it. The powers-that-be are risking very little.
