The new "Guardians of the Galaxy" movie trailer looks fantastic. Bradley Cooper is stealing the show as Rocket Racoon.Rocket Racoon made his comic debut in the early '80s in an issue of "The Incredible Hulk." I never thought in a million years that Rocket Racoon would ever be in a major motion picture, but here he is. Bradley Cooper is the voice of Rocket and he literally steals the show in the "Guardians" trailer. "Guardians of the Galaxy" hits movie theaters in August.
