Hate treading on other peoples toes (territory), but I emailed this on to Gom this morning and no post with it in yet, and I want to pass the links on to a couple of Anime news sites. So, I have stumbled upon the streaming trailer for this, and it's not on the Official Site yet - that link offered over there is dead. Again, sorry to do this to you Gom - completely unintentional stumbled-upon find. Nice one too.
Trailer (128k Stream) / 予告編 (128k Stream). 魁!!クロマティ高校 THE MOVIE.
Trailer (500k Stream) / 予告編 (500k Stream). 魁!!クロマティ高校 THE MOVIE.
This was found hidden away on a Japanese Movie News site, so it should be the first english-language way to find this. That I know of. Enjoy.
