That’s also why he contributed to Avengers: Infinity War and Avengers: Endgame, since the Guardians finally got to interact with other Marvel heroes.
In terms of the Guardians of the Galaxy Vol. 3 script, though, Kevin Feige confirmed that James Gunn’s draft will still be used, which Star-Lord actor Chris Pratt said earlier this month.
So it sounds like we don’t need to worry about Gunn’s ‘voice’ being completely wiped away from Guardians of the Galaxy Vol. 3.
although I do wonder how much of his script will be altered once a new director is hired.
