hmmm i thnk Trigun and Rurouni Kenshin would be really good as live action movies... i heard a couple of years ago (like when i was in the 6th grade) that they were making a live action movie for dbz (Funimation posted it) so what happened (or did they do it already)? it would be very interesting to see though rofl
It seems entirely pointless to make a movie that's already been made and change the style in which it's done. Why bother? The story already exists in the exact same medium, so why remake it with only an aesthetic different? It seems akin to making a movie twice with different actors and trying to sell both.
By all means, try to tell similar stories through live action films, but making a movie again with live action makes about as much sense as taking the script from Blade and making it an anime. It would be a waste of time and money.
