There's a story buzzing around right now, that Gary Oldman has decided to take a pass on doing the voice for General Grievous. It's stated in an announcement at his "managements" Web site, that he's unwilling to work a non-SAG film.
Here's a link to the Douglas Management Group Web site. The statement's dated August 23rd.
If this turns out to be true, and honestly, at this point I'm not convinced that it's true, then I'm for sure gonna be a bit dissapointed.
More to come... ?
