Quote. . . Supernatural The Animation turns out to be much bigger than previously thought. This morning, ANN reports that Madhouse, the acclaimed anime studio behind Death Note, Paprika and segments of Batman: Gotham Knight, is producing 22 episodes that cover the first two seasons of the live-action CW series: ?The anime project will not only remake the best episodes from the live-action version, but also depict original episodes not seen in the live-action version. Those original episodes will include prologues of the Winchester brothers? childhood, anime-only enemies, and episodes featuring secondary characters from the live-action version. . .
I haven't seen the show, but the premise could translate very well to a seinen anime.
Being a huge fan of this show, I will only be on board if Ackles and Padalecki are doing the voice overs.
