‘Avengers: Doomsday’: Kathryn Newton Confirms Return as Cassie Lang in MCU Sequel

Kathryn Newton confirmed in a video on her X account that she’ll be returning as Cassie Lang in Avengers: Doomsday. Her brief appearance in yesterday’s CinemaCon trailer was a surprise, as she hadn’t been previously announced as part of the cast back in early 2025. Marvel Studios has since given her a specially-sized chair with her name on it. Newton’s addition to Doomsday—which also stars Paul Rudd as her on-screen father, Scott Lang—is a great one. You can see her announcement in the post below.
