A fan film would be ambitious, hence why starting earlier the better. I doubt Mr. Toriyama himself would even care for several reasons. On the top of my head, he's retired (not 100% confirmed), Japanese authors practically endorse this stuff (look up doujinshi), and using a particular art style isn't patented (see Fairy Tail vs One Piece).
That aside, fan films are stepping on a gray area. However, I mentioned in my earlier post, are legal in several angles. We aren't making a rival game that is piggybacking off the success of CT. I'm interested in making a film promoting the sales of CT (this might be enough for SE to either not care, or even support it). I don't see Capcom trying to shut down megamanfilm dot com even though the movie is available for free since 2010 (they are even selling DVDs lol). Sega isn't trying too hard to block the Sonic film coming out. Heck, the original voice actor signed up to be Sonic...
I am looking for talented individuals that would humor me on this anniversary project (again it could not be a fan film, that's just my idea which I favor greatly). In particular: scenario writers, musicians, and machinima experts.
