Maybe the space thing was just artistic! They wanted to do something dramatic, a big battle in the big old space.. dramatic enough.
My bro (Fortnox) just pointed out to me that all Saiyans can breathe in space. This seems logical. when Vegeta and Nappa destroy Arlia, they stand around talking out in space. When Paragas is trying to stop Brolly destroying planets (on TWO occasions) they are both out in space, hopping from rocks. In The Worlds Strongest Team video, Gohan is up in space lookin fine. And in the DBZ intro, we see Vegeta in space going SSJ (Dunno when this is, I've only seen it on the intro). THEY LIVE! SEE! THEY LIVE!
Sinkaro I watched the film, I loved it, and I saw Brolly getting stabbed by some guy, with a dagger thru the heart. I just checked, definately a dagger. He should be DEAD DAMNIT! X_X
