A rumor has been surfacing on IGN & BatmanOnFilm.com that Warner Bros. might be mulling around the idea of having the next solo Batman movie to be an adaptation of Batman Beyond. WB considered doing this before they decided on going forward with Christopher Nolan's Batman trilogy, but I guess they want to take another shot at it. Rumor: Warner Bros. Mulling a Batman Beyond Live-Action Movie - IGN BATMAN-ON-FILM.COM - Will The Batman on Film Reboot be 'BATMAN BEYOND?' (7.17.13) Some are against the idea because it'd be confusing if WB wanted to make a BB movie around the same time that a Justice League movie is out, but I don't think that would really be a problem. They could just "that was Bruce in modern times, this is Bruce & Terry's story in the future". I'd think it would be awesome if Michael Keaton was cast as Old Bruce if this movie gets the greenlight.
