During the announcement of the upcoming Superman/Batman movie at this summer's San Diego Comic-Con, it was revealed that Henry Cavill would reprise his role as Superman, but we were all left wondering who would play the Dark Knight. The mystery is over, as The Hollywood Reporter is reporting that Ben Affleck has been cast to play Batman in the Warner Bros. film.

The selection of Affleck is interesting on a number of levels. The Oscar-winning screenplay writer, actor in numerous films and Argo director previously starred as Daredevil in the 2003 film based on the Marvel hero, and in 2006 played 1950s Superman actor George Reeves in Hollywoodland. Last fall Affleck had to repeatedly deny rumors that he would be brought on by Warner Bros. to direct a Justice League film. In doing so, he also noted that he had little interest in working on any comic book movie at the moment -- after having a bad experience on the critically panned Daredevil --  but said he'd return to super hero films “if it was the right one and if I thought I could do it well.” No word yet on whether or not the film will involve every actor who's ever played Superman or Batman flying out of a Boom Tube.

The Superman/Batman film, notably referenced exclusively as a Man Of Steel sequel by The Hollywood Reporter, will be directed by Man Of Steel director Zack Snyder and co-written by Snyder and David S. Goyer. In addition to the news of Affleck's casting, Warner Bros. announced a release date of July 17, 2015.
