I knew almost nothing about Guardians of the Galaxy before The Avengers: Earth's Mightiest Heroes. After The Avengers: Earth's Mightiest Heroes, I knew that they were in space and the team included a raccoon with a machine gun, and an ent.
After this trailer, I still know pretty much that. But damn, I wanna go see it!
PS: Rumor has it that Captain Marvel may make an appearance in this one, which I would be all over like a bad suit, but I don't know if that's actually happening or not.
