Realizing, now, you're only 5 years younger than Patrick Stewart was when he started filming TNG (47)
Which is even more mind-blowing when you consider that a lot for these long-awaited sequels...the protagonist in the sequel is as old, if not older than, their mentor in the original.
I could be mis-remembering on some of these, but...
Creed: Stallone was older in this movie mentoring Apollo Creed's son, than Mickey was in the original Rocky
TopGun Maverick: Tom Cruise is >= Tom Skerritt (Viper) in Top Gun
Cobra Kai: Ralph Macchio >= Pat Morita in Karate Kid
