The much anticipated movie, Captain America: Civil War, was announced with all the other Marvel Phase 3 movies. This movie was only made possible by Robert Downey Jr.'s acceptance of returning into Marvel and not just for Infinity War. This made fans go insane with excitement. This fan (Alex Luthor) made an amazing trailer using clips from the Avengers, Captain America: The Winter Soldier, Captain America: The First Avenger, Fantastic Four: Rise of the Silver Surfer, Ant-Man trailer, and the Avengers: Age of Ultron trailer.
And if you didn't get enough, here's a Black Panther fan trailer by Alex Luthor.
