The new batman man of steel movie wich is to be released in 2015 will feature ben affleck as batman.  The movie will be produced by warner brother studios and will be released in summer 2015.
Now to the man of steel movie which was a prequel not neccesarily to this movie but to the much broader dc universe that we had not yet seen in previos films. Super man showed his powers in the man of steel movie which leads me to question warner brothers studios statement saying that super man and batman would engage in a battle in the movie. The difference is obvious it doesent seem to make sense that the superhuman wouldbattle the vigilante crimefighter. It may be a mental battle or superman may have some disatvantages like kryptonite or maybe not manting to reveal his identity ,sadly it will probably remain unclear until the movie is released.
