At the end of Avengers: Infinity War, we see numerous super heroes
vanish since Thanos was able to assemble all of the Infinity Stones and do as he wished, making 50% of the entire population of the universe disappear.
I've done a bit of digging, and I can't find out if anyone has asked/researched how the superheroes that were in the film were selected to be part of
specifically, by the writers and directors of the film.
I'm curious because a small part of my inner-nerd really hopes that the directors rolled a dice, or used some other form of random picker since supposedly that's exactly what Thanos did.
To be clear, this is not a request for an in-universe explanation. How were the specific heroes and other main characters chosen by the makers of this film?
