The only thing I know about Dragonball Z is that there's a ball involved, somehow, and maybe a dragon fits into the picture later on. And I have to say, the new, very very short clip from the movie that surfaced on YouTube doesn't tell me much else. It appears to be from a Japanese TV show, which means even the title is in Japanese-- I'm only going on blind faith that this is actually from Dragonball Z, and not some alternate reality version of Lord of the Rings.

But based on the helpful information in the comments below, the clip seems to feature Goku, the main character of the Dragonball Z series, when he discovers the first Dragon Ball and the uniform he wears throughout his journey to find the other balls (that last part is just a guess; correct me if I'm wrong). Either way, the clip should be thrilling for anyone anxiously awaiting the live-action version of this hugely popular series. Check out the clip below; it's sure to be only the beginning of what we'll see before the movie's April release date.
