This is the English subbed trailer for the upcoming Supernatural Anime series that will be released in Japan in of February 2011. No word yet on the English Language release date.
Although the original TV show has its share of violence, it's nowhere close to the level of violence and blood that will apparently be in this release as indicated by this trailer. A true anime feature. And that isn't necessarily a bad thing.
According to Anime News Network, “Warner Home Video will ship Supernatural the Animation on Blu-ray and DVD in Japan on one starter disc on February 23, 2011, followed by two boxes on March 9 and April 6. (The first disc and box have been delayed by one month.)”
Apparently Jared Padalecki and Jensen Ackles (Sam and Dean Winchester on the live action series) will be dubbing two episodes in the second box set into English.
