Despite not being listed as a film being released in 2020 or 2021, the third Guardians film will likely begin filming toward the later part of next year.
In fact, Guardians of the Galaxy star Sean Gunn admits the creatives involved with the production are now putting their heads together to work out the schedule for principal photography. Talking with ComicBook.com earlier in the week, Gunn says that while a filming start date hasn't been determine as of yet, they're actively feeling out those involved in the production for scheduling and the like.
"We're kind of figuring that out now," Gunn says. "I think it's going to be a little bit, but I'm definitely looking forward to it. It's going to be fun. But I don't know for sure when that's going to be, but it's definitely coming."
Previous reports suggested the film would begin production in 2021 before being revised and saying it'd be bumped up a year. Now that we know Guardians of the Galaxy Vol. 3 won't get a release date before 2022, it's becoming increasingly likely the film will begin filming this time next year or shortly thereafter.
James Gunn is currently set to begin production on Warner Brothers' The Suicide Squad relatively soon, which means the filmmaker would be done shooting that by the end of spring, at the latest. That movie's release date is currently August 6, 2021, though it seems the date would move up with WB fast-tracking the film.
