in ref to the trailer within the game?
well, i messed around with google, for a second, didn't find anything conclusive, probably bec of that trailer
some things to try:
ギルティギア = guilty gear
のアニメ = the "の" is for possessive, can try "アニメ" = anime by itself also
or check Arc System Works or Sammy for info
Guilty Gear movie? I can only hope it's animated. Actually, 2D fighting game movies never turn out right. They're always screwed up badly. If Guilty Gear is gonna be animated, I hope they get the animation right. Hmm something tells me that a movie is gonna be quite a task (not just the animation).
