What about Boseman (sorry, but he was a high school senior in 1994/1995), or Renner or, or hell, how old is Damon going to be now going into doing a new set of Bourne films? If you learned that Damon got to cast to replace Evans Tue. morning, would anyone really hold his age against him?
Personally I would have liked Anthony Mackie or Michael B Jordon as Black panther,but Mackie is already Falcon and Jordon is already Human Torch so it had to be Boseman
There aren't many talented Black male actors in that age range, so they didn't have much of a choice, while there are so many female actresses in the 29-35 range so they have a luxury to chose
Renner's Hawk-eye for all practical purposes, is a side-kick, he will probably get killed within a couple of movies and he is never gonna lead in his own movie so it doesn't matter for him.
Captain Marvel is gonna be Marvel's (and cinema's in general) first female led superhero movie, Marvel is gonna want to milk the character for as long as possible.
I personally loved the Bourne trilogy and I believe Jason Bourne's story has come to a respectable end, I don't want them making new ones and no, as much as I like Matt Damon, I wouldn't want him as Captain America
And if you wanna make that comparison, Matt Damon was cast as Jason Bourne when he was 31, not 39
How old is Affleck who is going to play Batman IN A ZACK SNYDER FILM (therefore a Batman that we can be assured will be very physical)? Again, nobody holds these guys' ages against them. And as for the differences between Carol and Cap... Sorry, but there's far more need for CGI SFX character replacement in the film with the hero that flies, has titanic strength and shoots energy blasts, often while in space mind you, as opposed to a "peak human" super soldier, whom you can have the actor do certain things live on set from start to finish. And by the way... When Cap was in the planning stages there was the call for lots of actors over 35 to play the part from many people.
Wasn't there news that Affleck was struggling to build muscle and had resorted to steroids? And didn't even Hugh Jackman say that he will give up the role of Wolverine sooner than later because he can't keep up with the work-out? Its difficult in the 40s, both for males and females
The top two choices for Captain America were always Evans and Krasinski, and Krasinski was 31 during that time
I don't get the obsession with Theron, If it someone similar to say Zoe Saldana, who has been in her fair share of action movies, I wouldn't have worried but Theron never came across as an action heroine to me
