I think that Sean Connery needs less screen time than before. I can buy an older Indy running around and doing his old routine, but toting Sean Connery around, who will appear even older, will be a real stretch of the imagination. Actually, it'd be great if he could be in it, but riding horses and being held hostage in tanks? No way.
I think Indy's age should be used to comic effect. There shouldn't be a comedian sidekick this time around. I think his age leaves the door open for enough humor already.
It'd be neat to have Short Round back, but I want to remember him as a kid. If I saw him again, I'd see him as "the 30 year old guy that played Short Round". If he had a brief appearance, great. But throughout the whole movie, and it'd seem like they couldn't come up with anything better.
Pat Roach needs to come back. I'll be looking for him throughout the entire movie, and I missed his bigger part in LC.
I am still in the middle in deciding whether Indy should have a 30-year-old girl running alongside him.
I mean that's always been great, but what about Karen Allen? Wouldn't it be great to have her back? Seeing him with a 30-year old would be like Six Days, Seven Nights again.
