News is out, though yet to officially confirmed, that James Wong will be directing the 20th Century Fox adaptation of Dragonball Z. Included with this is also a cast breakdown, which if true, shows that the adaptation is infact Dragonball, the original series (with a much more managable cast size) instead of DBZ.
The basic plot keeps fairly true with the original series, greatest noticable differance being Goku, who begins the series as a socially unaccepted 18 year old school student. This brings to question what era or culture this movie will take place in, for none is given as of yet. Other main characters include Bulma, Yamcha, Lord Piccolo, Gohan and Master Roshi.
