At this particular moment, no director, writer, 
or cast has been chosen for the "supposed" DBZ 
live action film. Yes, Fox did buy the rights to 
the franchise, but that does not mean that they 
are going to jump head first on this right away. 
Fox had the rights to X-Men for years before 
making the movie. The idea is get all your ducks 
in a row first. I doubt you will see a movie 
until at least 2004.

Oh, and if the rumors are true and they do hire 
Keanu Reeves as Goku, I think I'll sit that one 
out. It's bad enough that I sat through a film of 
him playing Siddhartha. They would be better off 
in my mind going with the original Dragonball 
series rather than jumping directly into the Z-
saga.
