For the less informed:
Six animation directors submitting their own minisodes put together as a movie in a style similar to the Animatrix.
Bruce Timm is still the head director and producer, and he is known for great work.
Takes place in the Batman Begins and The Dark Knight universe, No Jack Nicholson Joker and Jim Carrey Riddler here. Whole movie takes place inbetween Batman Begins and The Dark Knight
Kevin Conroy, i.e. the best Batman since Adam West and Michael Keaton, will be voicing Batman yet again (voiced Batman in the Animated Series and Justice League).
A Few of the villains that will be appearing are Killer Croc, Scarecrow, and Deadshot.
The Movie has leaked onto Limewire in the past, the release date is in July.
The Original Batman of the Golden Age carried a Gun, even after Robin joined him, the mainsteam universe Batman carried a gun until he met up with Dick Grayson. So for those saying "BATMAN DOESN'T USE GUNS", you are mistaken.
