Just had an idea... or more like a flash -

you know how they went from lasers to bullets in Terminator Salvation?

It was a pretty bad movie, in my honest opinion, but I liked the idea of bullets.

So what I'm trying to say is - how cool would it look if stormtroopers fired bullets instead of lasers? You could have some serious blood spewing in the opening scene. And it would make the Vader entrance even more intimidating. Cause you would be, like, "Whoa! Those guys were nuts and killing everybody! And this is their leader?! He must be one twisted S.O.B.!"

... just imagine that white corridor all bloody and everything, with stormtroopers bodies lying on the floor and then... Vader appears!

Now is that impressive or what?

And also it would be interesting to hear different sound effects in that scene.

I know that R-Rated stuff isn't exactly Star War'ish, but since we're talking about RADICAL changes...

EDIT: I mentioned making Vader even more intimidating - how about putting some mechanical sounds to his movements? It would seem logical, since he's part man, part machine. And you would have to guess if he's a robot, or is he really a man?

People have always been terrified of tall, intimidating-looking robots XD

And what about his voice? How about making it a little bit lower? It would sounds more demonish.
