The action movie actors you mentioned. Let's see...Expendables, which was built around the idea of the old action stars. However, what young ones do you remember from those movies?
Harrison Ford? What? Indiana Jones? I've been saying recast Indy this whole time, guess what other people kept complaining about? Recasting Indy 😛 Just like how people complained about recasting T'Challa. To many people while at the idea of a different actor playing a role, when the whole idea is it's called acting. It can be recast.
I can't think of any action movie Clint Eastwood has been doing.
I need examples of actresses in their 40's playing someone in their 20s as I can't think of any movie that's done this. I've heard them complaining about being 28 playing the parent to a 20 year old (Rachel Weize at the time and why she didn't do Mummy 3, I believe it was).
Of course always the 20 somethings playing high schoolers, but you know...working with kids who can't work the hours.
Yes, I am for new younger stars. However, I go back to them failing and so big budget movies get nervous casting them because people aren't showing up for them.
