The inevitable passage of time is the biggest hurdle that the Marvel Cinematic Universe is going to have to overcome. We all know that these actors don't want to play these roles forever — and they're eventually going to age, unlike their comic counterparts. The Costco Connection got a chance to interview Kevin Feige and asked him about the idea of recasting sometime in the future.
That's what we can look to in the comics. And that's why these characters are so relevant. I talk about 10 years of movies, but it's 50-plus years of these characters in the comics. And they're just as relevant and popular. And that's because they do get updated. They change with the times. … I have no doubt that all of our actors, who are in peak physical shape, have got another 50 years in them to be heroes. In terms of the specifics of how we will evolve the characters, thankfully, I don't have to really think about it yet. 'Cause we're still finishing what we started here with Avengers: Infinity War.
It sounds like Marvel isn't too worried about the recasting of major characters. Now that they have pretty much the entire library back, save for the stuff that Sony has, they have enough characters that should one of the various Chrises decide to retire, they could pull from the well of new characters to explore.
Summary: As the Avengers and their allies have continued to protect the world from threats too large for any one hero to handle, a new danger has emerged from the cosmic shadows: Thanos. A despot of intergalactic infamy, his goal is to collect all six Infinity Stones, artifacts of unimaginable power, and use them to inflict his twisted will on all of reality. Everything the Avengers have fought for has led up to this moment – the fate of Earth and existence itself has never been more uncertain.
