Make this into a live action movie
It would really be something fresh after many years of increasingly over the top yet stale superhero movies. I enjoyed Batman Begins but am not too fond of the two that followed. Batman Beyond would offer something enticing, a chance to present new characters and storylines worked into a futuristic Gotham, as opposed to the silly ticking bomb theme of TDKR. I'd like to see some cool villains like Inque or Blight rather than the mediocre Bane and Catwoman.
Who would you cast as an elderly Bruce Wayne and Terry McGinnis? My choice would be Clint Eastwood as Bruce or maybe Christopher Lee if he can pull a convincing American accent. Not sure about Terry.
