The Infinity Stones are six artifacts that determine the existence of the universe. They have been part of Marvel since the comics of decades ago, but in the cinematographic universe developed by Marvel Studios they appeared as the main focus of a plot in Guardians of the Galaxy Vol. 1.
Yes, we know that the first notice is that of space, in the post credits of Thor. What we mean is that in Guardians 1 it began to be that element on which the entire plot of a movie revolves. It was in that 2014 movie, with the gem of power, that these elemental crystals began to gain the importance that is concluded in Avengers: Infinity War and Endgame.
So, that means that the great person responsible for telling in a mystical way what these gems meant was James Gunn, who debuted as a writer of Thor’s post-credits scene where the space scene was seen with Benicio del Toro making his debut as The collector.
With Guardians of the Galaxy Vol.3 as the main focus, James Gunn finds himself giving interviews left and right. In one of his many statements, he has revealed that the story about the infinity gems occurred to him in just an hour and a half.
“I wrote that scene in an hour and a half, it just occurred to me what the infinity stones were while I was writing it. And in the end everything in Marvel has been based on them. Marvel Studios was like, ‘We’re thinking of adding the Power Stone,’ and I was like, ‘Wow, that’s great. The Collector has the gem of power ‘And in the end I invented all that nonsense, ”he recounted as he collects Espinof.
