Check out this article:
For the basics, Mark Hamill is confirming that the big 3 plus Billy Dee and Anthony Daniels are "in talks" about Episode VII. There are no official mentions of anyone having signed anything. But honestly, I think this is a pretty good sign. I'll admit that originally I was kind of less than thrilled about the idea of them all coming back, for fear of what they might do to them. But, well, nostalgia is getting the better of me and how can I not want the opportunity to see my favorite movie characters ever on screen again after over 30 years?
Of course I still have fears of what awful things they might do to them. But I think we need to take that chance here. I'm not sure they could screw things up worse without them than they would with them. The other good news is it mentions they would not recast if someone didn't want in. They'd simply write them out. Let's be honest: these guys aren't having their doors pounded on to get them to do acting gigs. I don't see much potential downside to them reprising their roles. It's not like they have to worry about being type cast and ruining the rest of their careers. Their careers are almost over, as sad as that is to say. There is really not much reason for them to not accept this role and I have no doubt the money would be worth it.
So, come on and discuss how you feel about this news. And remember, it's much easier to comment now, so get to it!
