Marvel changed the face of Hollywood with its series of interconnected movies (Iron Man, Thor, Captain America, and Hulk), culminating in the massive crossover success of Marvel's The Avengers. The movie world they've created has become known as the Marvel Cinematic Universe. And it's a gold mine. Ever since, other studios have been crawling all over themselves to create their own cinematic universes, in particular DC with Batman v Superman and the upcoming Justice League movie. But in December 2015, Paramount surprised everyone with an announcement that they would be working with Hasbro to turn its hit G.I. Joe movies series into a cinematic universe. And the other properties they planned to combine it with took everyone by surprise.
