MojoKid writes: The first official trailer for Marvel's upcoming Captain America: Civil War hit the web yesterday and it's looking pretty fantastic. It appears that Cap, Bucky, and Falcon are joined by Scarlet Witch and Barton when the action heats up. Stark / Iron Man is joined by War Machine, and it seems Black Widow is on his side as well. Why Tony and Cap are at odds is the main premise of the movie – the powers that be no longer want Cap and the rest of The Avengers operating unchecked and it seems some of The Avengers are apt to agree. Also fighting Cap and Bucky is a new addition to the Marvel Cinematic Universe, Black Panther — whose actual name is T'Challa. He is the heir to the kingdom of Wakanda, which if you remember is the African nation, and only place on earth, where Vibranium can be found. Vibranium is the metal used to make Cap's shield, and it's what Ultron was ultimately after. Black Panther is a gifted tactician, strategist, scientist and master of unarmed combat according to the Marvel Wiki. Who we don't get to see are Scott Lang, otherwise known as Ant Man, Crossbones, and the amazing one himself – Spider Man. It's not clear if Spidey is going to appear as a young Peter Parker or the full-on Spider-Man, but Tom Holland has been cast as the amazing one in Civil War as well.
