Avengers: Doomsday cast update and release date

Avengers: Doomsday, the upcoming blockbuster from the Marvel Cinematic Universe, has received a recent cast update. Kathryn Newton, who plays Cassie Lang, is set to return for the sequel, which is scheduled for release in December 2026.

Actor and role of Cassie Lang

Kathryn Newton is known for her role as Cassie Lang in Ant-Man and the Wasp: Quantumania, which was released in 2023. In that film, Cassie becomes an active hero and gets her own superhero suit. Her character helps Ant-Man, played by Paul Rudd, fight Kang the Conqueror in the Quantum Realm.

Newton celebrated her return to the Marvel world, including by sharing a video on Instagram. In it, she shows a miniature director’s chair with her name on it, a nod to the Avengers: Doomsday cast reveal, where the actors’ names were shown on the backs of the chairs. “It’s small because Cassie is small too,” Newton says in the clip. “But sometimes she’s big. It depends on what’s happening.”
