Might be a bit too vast of an undertaking. My idea is to voice and score (plus sound effects) the online graphic novels and create a kind of slide-show to make the closest approximation of an animation out of it as possible. The main problem here is procuring a cast. I think it would be possible, though if you recruit Heroes fans worldwide.
I guess we couldn't use copyrighted music, but there is a website, freeplaymusic.com that could facilitate the score portion of the project, and it would be completely legit. The actual Heroes soundtrack might be OK to use, as well as this would be a not-for-profit project (it would fall under the same category as SW fanfilms, really).
