James Gunn

It was discovered after James Gunn wrote the script for Guardians of the Galaxy Vol. 2 that Marvel didn’t own the character of Ego, the Living Planet. Instead, the rights belonged to FOX Studios, and James Gunn did not have a backup plan. Fortunately, FOX needed the permission from Marvel Studios to change key details about the Negasonic Teenage Warhead in the Deadpool film, which Marvel happily allowed in exchange for Ego’s character rights.
