With James Gunn having now confirmed he’ll be returning for Guardians of the Galaxy Vol. 3, the writer/director has revealed that he’s been debating changing the established canon in order to tell the story he has in mind for this third film.

Speaking at E3 (as reported by Cinema Blend), Gunn explained, “I’m writing Guardians of the Galaxy Vol. 3 and I finished the first draft of the treatment yesterday, which I’m excited about it and I feel really great about it. But there’s one little thing that I had in the first movie. Now, Marvel, MCU canon is crazy and I’ll get super geeky for two seconds. There’s the 616 universe which is the Marvel Comics Universe, which people get hung up on that canon, and then there’s the MCU, the Marvel Cinematic Universe, which has a separate canon which is inspired by but not exactly the same as the 616. I did something in the first movie of Guardians where it was in the background but it was distinctly there, and people know that it’s there. And I’m like goddammit because I have a really good storytelling reason for breaking the canon, and I stayed up last night figuring out if I’m gonna do it or not. I still don’t know.”

When pushed on the matter, Gunn added, “In the first movie there is the mugshot sequence where the characters go through and they’re going through the mugshots and having their picture taken and the Nova Corps. has information about each of the characters coming up on their little machinery. Now, those things are something that your average viewer doesn’t see at all and doesn’t read, but there’s a lot of background I put into those things about who they’ve worked with, where they’re from, what’s going on. And it’s one of those things that I’m thinking about changing.”

The scene that Gunn references sees a few brief background details given on our cosmic heroes, most notably that Gamora is the last survivor of the Zehoberei race; Rocket has his roots in Halfworld and has ties to Lylla; and Groot is teased as having his Planet X origin.

This could all be nothing or it could well be something but, either way, expect more on Guardians of the Galaxy Vol. 3 as we get it. Up next for the team is an appearance in May 2018’s Avengers: Infinity War, where they’ll come together with Earth’s Mightiest Heroes as Thanos finally steps out of the shadows.
