1999 might have been an okay time to start a project like that, Mark and Harrison weren't looking their worst at that time (sorry Carrie, can't say the same for you), but 14 years in the future, time has caught up to them. I know they can work all kinds of magic on them, but I still don't think that is a movie anyone really wants to see. The ship has sailed for our old heroes. Still, it'll be cool to see them play a role in the new film.

Yes photos and videos like ^ are what worries me to. Nobody wants to see a embarassing 'Kingdom Of The Crystal Skull' style old-folks reunion. If they are coming back, they have to have it written into their contracts that they spend the next two years at the gym. I'm not exactly an exercise freak myself but nobody is gonna be stupid enough to pay me a few million dollars to star in the biggest SF franchise ever. If they were, I'd be eating nought but brown rice and salads for two years, spending every minute doing pushups and signing up for fencing lessons!

Let's hope they get small, dignified and meaningful cameos. Playing OT style archetypes like:

Luke = The new old Ben

Han = The new General Dodonna

Leia = The new Mon Mothma

Hamill's role would be the largest if he's gonna be the mentor/father figure. Plus he's a damn fine actor.
