James Gunn is ready with the first draft of 'Guardians of the Galaxy Vol 3'

Director James Gunn has revealed that the first draft of Guardians of the Galaxy Vol 3 is ready for editing.

The 50-year-old director, who has been busy working on the third installment in the Marvel's superhero film series, has said he might change a piece of MCU continuity he had established in the original film, reported Screen Rant.

Speaking at E3, Gunn said, "I'm writing Guardians of the Galaxy Vol 3 and I finished the first draft of the treatment yesterday which I'm excited about and I feel really great about it.

"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 the other night figuring out if I'm gonna do it or not. I still don't know."

He continued, "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," he added.

The action-fantasy features Chris Pratt as Star-Lord, Zoe Saldana as Gamora, Dave Bautista as Drax, Bradley Cooper as Rocket and Vin Diesel as the fan favourite Groot.
