I hope this rumor is true! I loved the Animatrix, both the visual appeal and what the disc contributed to the larger storyline.
David Goyer is David Goyer (love him or leave him), but Brian Azzarello is a real talent. I admire his work on Loveless, 100 Bullets and Batman Broken City.
From batman-on-film.com (via Ain't It Cool news):
"Set in the period between BATMAN BEGINS and THE DARK KNIGHT, this brand new adventure follows BATMAN as he unravels a mystery over six original stories done in the style of Japanese Anime. Each of the six original stories has been written by a highly respected screenwriter or comic book creator. The talent includes Academy Award nominee Josh Olsen (The History of Violence), screenwriter of the BLADE films and BATMAN BEGINS David Goyer, and famed comic book writer Brian Azzarello, among others. The Batman Anime DVD is viewed as a perfect companion piece to BATMAN BEGINS and THE DARK KNIGHT. The original stories introduce a number of classic characters from the DC Comics BATMAN universe as well as following up on characters and story lines that were introduced in BATMAN BEGINS. "
