Kathryn Newton Confirms Cassie Lang Will Be Back for ‘Avengers: Doosmday’

Kathryn Newton is returning to the Marvel Cinematic Universe as Cassie Lang.

The 29-year-old actress posted an Instagram reel on Friday (April 18) to confirm her return. Her last Marvel movie was the 2023 film Ant-Man and the Wasp: Quantumania.

In her video, she told her fans she got a “special” package while working and was excited to open it on camera.

Then she slowly reveals a small director’s chair with her name on the back. It’s how Marvel has been announcing all of the returning cast members for Avengers: Doomsday. But if you needed further proof, when she turns it around, the Doomsday logo is emblazoned across the front.

She also joked that the chair is so small because Cassie can get small, “or sometimes she’s big, it depends what’s happening.”
