This screen adaptation would have been produced by Dini and Alan Burnett, his fellow producer on the Batman Beyond animated series. Boaz Yakin (Remember The Titans) was attached to direct. It would have told the origins of the new caped crusader, Terry McGinnis, and his relationship with an elderly Bruce Wayne.
There were rumors this past July that Warners might rekindle the Batman Beyond live-action movie, but then just days later at San Diego Comic-Con the studio announced that Batman vs. Superman was in the works for summer 2015.
Check out what Dini had to tell Smith about the project in the clip below (warning: NSFW language). Via Voices From Krypton.
