Avengers: Doomsday Secrets: Hailee Steinfeld's NDA Holds Tight

As the December 18th, 2026 release of Avengers: Doomsday approaches, speculation about its cast and plot intensifies within the MCU fandom. Hailee Steinfeld, who portrays Kate Bishop, has reportedly maintained strict confidentiality regarding her role, even from her husband, Josh Allen. This situation highlights Marvel's rigorous security protocols.

Steinfeld's commitment to her non-disclosure agreement was noted during a recent television appearance, where she deflected questions about her participation in the upcoming blockbuster. Her discretion underscores the lengths to which actors must go to protect the Marvel Cinematic Universe's secrets.

Kevin Feige, Marvel Studios' president, previously confirmed that the initial cast list for Avengers: Doomsday was not exhaustive. This was further evidenced by the return of Chris Evans as Captain America, as seen in promotional materials. The multiverse concept allows for numerous narrative possibilities, making Kate Bishop's inclusion a plausible development.

Steinfeld's character, Kate Bishop, was introduced in the Hawkeye series and later appeared in The Marvels, where Kamala Khan began assembling the Young Avengers. While the future of that team remains uncertain, the possibility of Kate Bishop appearing in Avengers: Doomsday is high, especially given the trend of surprise cameos and character returns in recent MCU projects.
