Yeah but he was 87 when he made"The Mule".Yeah, he did well enough as old Han and Deckard, neither of which required major stuntwork or hand to hand fighting even in the earlier films but Indy has always been about running, jumping, punching and the like.
For decades I've felt that the gold standard for an aging actor returning to his roots was Clint Eastwood in Unforgiven and yet he was still only *62* in that film, not 78!
