Not sure about this casting news.
Billy Dee Williams, fine, it's been too long since we've seen Lando. I'm shocked that he's 81 now, but I shouldn't be - it's 35 years since Jedi!
Anthony Daniels - I guess he's only lending his voice to the film (it'd be cruel to swueeze an old man into that costume!), but I find C3PO more and more irritating with every new appearance. Give him something to do, or leave him out!
I really have my reservations about including Carrie Fisher. Especially as it seems that they will be recycling footage from the cutting-room floor of episode 7, not even 8. They had a chance to kill Leia off with dignity in the last one, but didn't do it, and I now worry that she's being shoehorned into the new film for the sake of it. I don't relish saying this, but I do hope that Leia dies early on in episode 9, so it's easier to get on with enjoying the movie.
