'Avengers: Doomsday': Thor reunites with Chris Evans' Steve Rogers

The first teaser for "Avengers: Doomsday" has dropped, and it's packed with action.

In the two-minute video, nearly every major hero across the Marvel Cinematic Universe (MCU) joins forces to take on a new threat: Doctor Doom, portrayed by Robert Downey Jr.

The lineup includes the Fantastic Four, the X-Men, Sam Wilson's Avengers, the New Avengers, Thor, and Ant-Man.

Another major highlight? The return of Chris Evans as Steve Rogers, which marks his first appearance in the MCU since "Avengers: Endgame" in 2019.

The upcoming film also marks the final full-length Marvel project led by Andy Park as Marvel Studios' Director of Visual Development before his exit from the studio.

“Avengers: Doomsday” is set for a theatrical release on December 18.
