The Marvel movies, to date, have been building towards next year's Avengers: Infinity War. Thanos (Josh Brolin) is coming, and he's collecting Infinity Stones along the way. So far, he doesn't have any, but the Guardians of the Galaxy encountered the Power Stone in their initial adventure, and the sequel will address some interesting questions tied to it.
While visiting the set of James Gunn's Guardians of the Galaxy Vol. 2, I asked Marvel President Kevin Feige point blank if the sequel would have an Infinity Stone in it, and he bluntly replied, "No." But he did explain:
There is something unusual about that. Does that mean there's something unique about Peter Quill (Chris Pratt)? His genetic makeup is strange. We know that he has a human mother, and an... alien father (Kurt Russell). But Marvel is keeping its cards close to its vest when it comes to Ego the Living Planet.
In case you don't remember the scene, it's here:
My guess? We will learn something special about Star-Lord in Guardians of the Galaxy Vol. 2, and it will tie into his father. James Gunn spent a lot of time telling us on set that the driving theme of his sequel is the relationships between fathers and sons, and how Peter Quill really will be pulled between his surrogate dad, Yondu (Michael Rooker), and his newfound father, Ego (Russell). We're looking for answers on Infinity Stones, but it doesn't sound like clarification on the Power Stone is going to happen in this installment. Instead, we'll likely have to wait for further explanations in an upcoming Marvel movie... probably Thor: Ragnarok (as the God of Thunder did leave the Avengers to go in search of details on the Stones).
Guardians of the Galaxy Vol. 2 opens in theaters on May 5. And for more information on Upcoming Marvel Movies, click that text.
