Well, from what I've seen, a lot of the movies Keanu has been in, he has to create his character scratch. I know that probably doesn't make a whole lot of sense, but lets look at it this way. In Constantine, his character already existed in comics, so he had material to go off of, and I think he did a pretty good job. Just to quickly go off topic, look at Ron Pearlman. He read EVERY Hellboy comic he could get his hands on (which if I'm not mistaken was ALL OF THEM), and he did an OUTSTANDING job of portraying Hellboy. Now back to Kenau. Keanu is a fan of Cowboy Bebop, which we all know is an animated series. He has HOURS of source material at his disposal for research. Couple these two facts with the facts that he doesn't want someone who A) isn't a fan and B) just wants to make a buck, to screw this up. And as a fan of the series he doesn't want to personally screw it up, and make another Speed Racer or Dragonball, so he will more than likely give 100% on this movie. So don't count him out yet, and have a little faith.
