Hey Doctor M,
The irony about Ford looking old in KotCS is that if you watch his interviews in the special features where he's wearing the khaki shirt he wears in the film, he looks about 10 years younger than he does at the worst points of the film. In those interviews, he looks like 5-10 years have passed since Last Crusade rather than 20 years. When the cinematographer makes your talent look WORSE than they actually look, it's time to find a new cinematographer. Of course, that was hardly Kaminski's only fault in this film.
