Some directors are known for working with the same actors multiple times, and "Superman" writer/director James Gunn is definitely one of those filmmakers. So it should come as little surprise that at least three "Guardians of the Galaxy" actors make cameos in the upcoming "Superman".

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.

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.
