Gunn confirmed on Twitter that he has finished his first draft of the script.

The update follows Kevin Feige’s recent statement in an interview with Collider, which provided a rough idea of the production schedule for Guardians and the other MCU movies:

“James [Gunn] has delivered a draft and we begin official pre-production on that very, very soon. It’ll be shooting early next year. Captain Marvel finishes in about two weeks, Spider-Man starts in about two weeks, and then Guardians 3 will start early next year.”

So far, Guardians of the Galaxy Vol. 3 and the new Spider-Man sequel (Avengers: Infinity War. It is all but confirmed that most of the characters “killed” by Thanos will return from the dead. Given that Spider-Man and Black Panther were both erased and have sequels in place, it’s highly likely that Star-Lord will return to lead his team for one last ride.

It is important to note Gunn’s comment about how much “heart” was put into this project. It is evident that Guardians has indeed been a ion project as much as it has been a staple for Marvel Studios. Guardians of the Galaxy Vol. 2 was heavily focused on the theme of fatherhood, and Gunn delivered on his promise that it would be emotional. It only seems natural that his conclusion to the series will be just as moving. Given that production is expected early next year, audiences will not have to wait too long to see if Guardians of the Galaxy Vol. 3 is a satisfying finale.
