In the post-Ultron scenario, the world wants some supervision on the superheroes roaming around. Captain America, having been burnt time and again, does not want others to dictate his moves. But Iron Man agrees with the move of having superheroes on an official register. This divides the heroes of Marvel Cinematic Universe into two groups.

Unveiling the trailer on Jimmy Kimmel Live, Robert Downey Jr and Chris Evans (the two sides of the tussle!) unveiled the new poster of the film along with the trailer, marking the start of the third phase of the Marvel Cinematic Universe.

Directed by the Russo Brothers, from the looks of the trailer, the movie focuses on Captain America's perspective. The trailer features Captain's allies - Falcon, Hawkeye, Scarlet Witch, and his 'friend of almost a century' Bucky! On the other side, Iron Man, (maybe for the time being as we are yet to see all the superheroes involved in the movie) has his best friend, War Machine by his side. The Black Widow urges Captain America to not fight this war, but it's unclear which side she'll choose. Concept art for the film sees her standing by Iron Man along with the Vision and Black Panther.

The movie will see the first appearance of Black Panther and the new web slinger, Tom Holland as Spider-Man. The team is pretty much here minus The Hulk, Thor, and the Guardians!

The movie cast is as follows - 

Captain America - Chris Evans

Iron Man - Robert Downey Jr

Black Widow - Scarlett Johansson

Black Panther - Chadwick Boseman

War Machine - Don Cheadle

The Vision - Paul Bettany

Ant-Man - Paul Rudd

Sharon Carter/Agent 13 - Emily VanCamp

Falcon - Anthony Mackie

Bucky Barnes - Sebastian Stan

Scarlett Witch - Elizabeth Olson

Spider-Man - Tom Holland

Apart from these, Martin Freeman, Frank Grillo, Daniel Bruhl, and William Hurt, feature in (I think it's safe to call) this modern magnum opus! This feels like Avengers 3 three years before the actual thing even begins to shoot!

The movie is set to release on May 6, 2016. Now let's put the scene where Bucky and Cap are beating the hell out of Iron Man on loop!
