Kevin Feige and the Russo Brothers have revealed that Infinity War and Avengers: Endgame were in development for years before anything was ever committed to film.
One of the more popular Avengers: Endgame theories may have just gotten a significant boost from Marvel Studios boss Kevin Feige.
Avengers: Endgame will more than likely see some time trickery going on, which may very well have to do with one of the 14 million possibilities that Doctor Strange witnessed in Infinity War.
Obviously, this doesn’t go and outright prove any of the Avengers: Endgame theories with time loops, but it is certainly very interesting.
