We already know for sure that Japanese anime studio Madhouse is developing an animated version of cult TV series Supernatural. But are these leaked character sketches for demon-hunting brothers Sam and Dean Winchester? Signs point to yes.
AnimeNews reports that these images surfaced online after fans found them. They look very much like the art that's in the background of the Supernatural Animation logo, so it's likely that these character sketches are genuine - though of course they may not be the final versions of what we'll see when the anime hits next year.
As thrilled as I am to see Sammy and Dean with anime hair, what I really want is some concept art of the monsters and demons they'll encounter.
