58 isn't exactly young, yeah but it's a leap from 58 to near 65. As we get older especially pushing 60, 7 years can age you quite a bit. Like I said look at Six Days and Seven Nights to now, and see the difference between a 55-56 year old Ford to now a 64-65 year old Ford in Firewall. Every pic will be a bit different, and don't forget he gets makeup too like every other movie star.
"Most scrutinized actor of all time due to his age," I don't know about that. You could say that about every 50-60 plus year old former action star, who attempt to take on roles they made famous in their youth. Stallone is one example, and Schwarzenegger is another. Or Willis for that matter. They are all being scrutinized for their ages.
I think it would be ridiculous too if they make him up too much, and the cgi comment was a joke. Yes he still looks great for his age, but he's an older man now and not the 46 year old we last saw donning the fedora.
