In a recent update, James Gunn confirmed that there is a secret project lined up for DCU. He said that he has kept it tightly under wraps since it is quite unique, and he is concerned that if details were to get out, someone else could copy the idea.

James Gunn, the writer/director of 'Superman' and co-head of DC Studios, opens up about his social media presence, this summer's event film, and what's coming up next in his superhero universe.

And of course, Gunn's own brother Sean Gunn, who plays Maxwell Lord in Superman, portrayed Rocket Raccoon's physical motion capture performance as well as Kraglin, the Ravager turned Guardian who inherits Yondu's special arrow.
