Yes, I was thinking The Animatrix too while I read that.I loved The Animatrix, maybe I should check out some of the other anime short anthologies that were made like that Batman one and stuff
I can take or leave The Matrix but I enjoy The Animatrix. Likewise, I have no particular interest in Batman, but I enjoyed (and need to rewatch sometime) Batman Ninja. (I can't deny that it helps knowing that the latter is written by Kazuki Nakashima of Gurren Lagann and Kill la Kill fame. )
The list of studio names in that trailer is highly impressive — Trigger, Production I.G, Science Saru...
I'm not even a massive Star Wars fan or anything and yet I'm interested in this. Exciting indeed.
