Yeah, I think it is.
This file was recently leaked over the internet. I'm almost positive that it is the first draft of the live-action Dragonball movie script. How can I tell this is the first phase? Partly because the dialogue is so open and to the point, it's like the writer is just getting his bearings on the different characters and how they function in the story line's scenes, which is what the first draft is really for.
Having said that I'm very confident it's not the shooting draft, I'm actually looking forward to the film. This version of the script implemented some pretty cool ideas, and I'm looking forward to seeing how this turns out.
