Eso cuentan los Hermanos Russo, aunque suponemos que no todos son superhéroes:
“We have so many characters we’re dealing with. We’re breaking ground on ‘Avengers: Infinity War.’ We have a board with 67 characters on it,”
También hablan de que en la Fase 4 los nuevos miembros de los Vengadores irán cobrando protagonismo en detrimento de los originales:
"Everything is finite, right? Nothing can last forever.
It's cyclical. Some New Avengers in phase 4 are going to become prominent and then maybe some Avengers might not be around anymore.
So, we'll see how all this plays out but you have to treat every character with respect.
I think it's interesting that if you've seen four or five movies with the lead character having an arc, I want to see some story telling from some of the secondary characters."
"We're focusing on that right now with Infinity War while we're breaking into those movies, is which characters can we pull to the forefront who potentially haven't had their own 'A' story arc to this point.
I think you'll see that the supporting Avengers are going to become primary Avengers."
