Ahead of the upcoming release of Spider-Man: Brand New Day, Marvel Studios has released the first official trailer for its next movie Avengers: Doomsday.

Released on July 20, the trailer begins with a battered sign that reads “Xavier’s School for Gifted Youngsters”.

“Something’s coming. Something we may not be able to deter,” said a voiceover, as Charles Xavier/Professor X (played by English actor Patrick Stewart) shields his eyes from what looks like an explosion outside the window.

The scene then cuts to the film’s antagonist Doctor Doom (Robert Downey Jr), who says: “Before this day is done, we shall be faced with an unthinkable decision.”

A shot of the Avengers Tower appears, and Thor (Chris Hemsworth) was heard saying: “I’ve fought with many warriors in my time.”

He enters a room with The Fantastic Four - Reed Richards/Mister Fantastic (Pedro Pascal), Sue Storm/Invisible Woman (Vanessa Kirby), Johnny Storm/Human Torch (Joseph Quinn) and Ben Grimm/The Thing (Ebon Moss-Bachrach), as they meet up with Sam Wilson/Captain America (Anthony Mackie), Bucky Barnes/Winter Soldier (Sebastian Stan) and Scott Lang/Ant-Man (Paul Rudd).

“They were far stronger than all of us put together,” said Thor. “And they died. They died facing enemies and threats that scared me far less than this one.”

Shuri (Letitia Wright), M’Baku (Winston Duke) and a group of Wakandans face off against Namor (Tenoch Huerta Mejía) and some Talokanil soldiers in the next scene.

There is a glimpse of Cyclops (James Marsden), with Gambit (Channing Tatum) fighting Shang-Chi (Simu Liu) in another scene.

“Everything that they sacrificed will be for nothing if we do not stand together,” Thor said in the voiceover, as Loki twirls his TVA card (from the Loki TV series, 2021 to 2023). M’Baku shakes hands with The Thing as characters like Shuri, Sue Storm and Bucky Barnes look on.
