well they already have a director, the guy who did X-Files and The One. they start production in Canada in november and there supposed to start shooting in the summer. from what they gave of what theyre doing for story they are making some big changes.

firstly its a DragonBALL movie, not DBZ. The big bad in it is going to be King Piccolo. Goku is apparently to be portrayed as an uncool/unpopular 18 yr old high school kid whos been fighting his whole life trained by his grandfather Gohan. when Piccolo surfaces he kills Gohan and before he dies he tells Goku to stop Piccolo and to do so he has to find Gohan's old sensei Master Roshi and to collect the 7 dragonballs (of course Goku already has the 4 star). At this point he is apparently going to be meeting Bulma who is portrayed as a twenty something grad-student type dealing with science. she is also looking for the dragonballs and already has the 5 star.
they eventually meet roshi who goes trains goku and goes with them on there quest. i know at some point they get attacked by Yamcha who they want to portray as the badass type despite the fact that he'd nearly vomit whenever he saw bulma in the show. yamcha eventually of course becomes a good guy. they say that theyll meet other friends along the way and that goku will be competing in tourneys so im assuming well see tien, chaotzu and krillin as well.
piccolo is apparently part of a demon alien race (which if they make sequels theyll probably change that in later movies to better suit nameks in the frieza saga since King Piccolo was relatively 'unique' in DB)and when he sees goku hes the one who tells him hes a sayian and that he should be helping him. at this point id imagine a big fight ensues thatll probably result in King Piccolo spitting out DBZ piccolos egg like in the anime.
so yea i dk, the changes they're making seem alright for translating to live action setting which lets face it when the emperor of the world is a big blue cat with a mustache they haveta do something. it looks like theyre shooting for a more contemporary setting though but good or bad ill be seeing it anyway cuz im a tool.
