Finally, at long last, the Avengers are assembling again!

The much-anticipated reunion of Earth’s Mightiest heroes can’t come soon enough. It’s been six difficult years for movie theater owners since their last heroic team-up in 2019’s box office sensation, “Avengers: Endgame.”

To the thrill of exhibitors from Seattle to Key West, Disney unveiled the first full-length trailer for “Avengers: Doomsday” at CinemaCon as part of the studio’s presentation to theater owners. Until now, Marvel has only offered four brief teasers focusing on Steve Rogers (formerly known as Captain America), Thor, the X-Men and the Fantastic Four, all answering the ultimate call to battle.

The brand new footage starts with Robert Downey Jr. not in the iconic role of Iron Man, but as the green-hooded, metal-faced villain Doctor Doom, as he prepares to invade the multiverse. There’s a shot of Professor Xavier (Patrick Stewart) looking out his X-Mansion’s window as a bright flash of light shines outside, signaling trouble. From there, it’s a flood of comic-book crossovers as Gambit (Channing Tatum) and Shang-Chi (Simu Liu) battle and Mystique (Rebecca Romijn) transforms into Yelena Belova, resulting in a Florence Pugh vs. Florence Pugh fight. Then, Thor (Chris Hemsworth) and Doom face off, but Doom catches Thor’s magical hammer Mjolnir with his bare hands.
