Guardians of the Galaxy Vol. 3 will finally start shooting in November July 26, 2021 by: Thanks to COVID-19 and director James Gunn's temporary removal from the project, production on GUARDIANS OF THE GALAXY VOL. 3 is getting started a little later than originally planned, but it will finally kick off later his year. While speaking with Collider recently, James Gunn confirmed that Guardians of the Galaxy Vol. 3 will start shooting in Georgia this November. The writer/director also said that the script has largely remained unchanged over the past three years. It’s basically been finished for years. I keep fiddling with different things and adding things, and figuring out permutations and stuff — I’m in the middle of doing another draft now — but it’s really small stuff in comparison to what it has been. It’s basically been finished since three years ago.
