Well, I was thinking they would be struggling against Communists instead. Something about Lenin wanting a certain artifact which would grant him eternal life or something. But that would probably be too much to ask for.

You're assuming Ford's age will match Indiana's.

Well I don't know, unless the computer graphics domain has improved enough to transform his face/body for a full lenght movie or an imaginative scenario could explain his wrinkles.

Winkles don't denote specific age. Erryl Flynn looked like he was 100 when he died at the age of 60.

Because Stalone is more of an athelete, he is a boxer and bodybuilder, and has worked-out on a regular basics all his life.

He also ate "a steady diet of giant pancakes" to put on weight for Copland - whats your point?

They made Patrick Stewart look almost as fresh as season one Picard for that X-Men 3 flashback, so another WWII Indy could probably be done. But a new concept with an old dog might still work best for a final sequel - assuming that Lucas/Spielberg/Ford call it a day after that one.

That was some of the worst digital touching up I have ever seen. He looked more like plastic than Eva Angelina's bustline.
