Marvel actor left out of Avengers: Doomsday cast reveal announces return and reignites our hopes that a Young Avengers movie is next

After we caught a glimpse of her in the Avengers: Doomsday trailer, Kathryn Newton has officially announced her return as Cassie Lang in the upcoming summer blockbuster.

The actor shared a video to Twitter where she opens up a package to reveal a tiny director's chair with her name on the back and the Avengers: Doomsday logo on the front.

You might recall that very long and rather dramatic Doomsday cast reveal where a new director's chair bearing the name of a cast member was shown every 11 or so minutes... and while it seemed like everyone and their mother was returning, certain heroes were left out. It was announced that Paul Rudd would be returning as Scott Lang aka Ant-Man, but his daughter, Cassie Lang (Newton), was nowhere to be found.

In the official Avengers: Doomsday trailer that was shown exclusively at CinemaCon, we briefly see Scott kiss his daughter Cassie on the forehead. This is exciting for a few reasons, but mainly because I've been dying to see the Young Avengers in the MCU. Now that Wiccan, Ms. Marvel, Cassie Lang, Hulkling, America Chavez, and Kate Bishop have all appeared in the MCU (with Speed making his official debut in VisionQuest)... it's time for a standalone movie.

During the Marvel presentation at CinemaCon, Kevin Feige and the Russo brothers appeared on stage and told the crowd that Doomsday picks up after the end of Avengers: Endgame. Downey ended up introducing the trailer, with Chris Evans later joining them on stage.

Avengers: Doomsday is set to hit theaters on December 28. For more on Marvel Phase 6, keep up with all the upcoming Marvel movies and TV shows on the way.
