Disney showcased the first proper trailer for the long-awaited next Avengers film, Avengers: Doomsday, as the conference closed on Thursday.

The clip gave the first look at Robert Downey Jr – who played Iron Man in 2019’s Avengers: Endgame – as the new masked villain, Doctor Doom.

The latest film, out on 18 December, brings together a host of Marvel characters old and new.

The trailer showed a fight between Gambit and Shang-Chi, played by Channing Tatum and Simu Liu respectively, and Patrick Stewart reprising his role as X-Men’s Professor Xavier. “Something’s coming, something we may not be able to deter,” he warns.

Chris Evans returns as Steve Rogers, aka Captain America, appearing before Thor, played by Chris Hemsworth, as the Norse god’s Mjolnir hammer flies into the former’s hands.

On stage, Evans told the CinemaCon crowd: “I said I would only come back if there was a real reason. And in Doomsday, there is a very real reason that these heroes need Steve Rogers.”
