AceShowbiz - Hailee Steinfeld has sparked rumors about her return as Kate Bishop in "Avengers: Doomsday". She was asked by a fan if she would join the upcoming movie, and her response sent fandom into frenzy.

While signing autographs at the Mexican premiere of her new supernatural horror film "Sinners", Steinfeld responded to a fan asking about her return to MCU. Amidst the chaotic environment and numerous fans vying for her attention, she gave a single nod.

Her seemingly shocked reaction after that nod only added fuel to the rumors. Fans suggested her demeanour changed because she realized that she had messed up, given Marvel's notoriety in safeguarding information about their projects.

The actress made her debut as the sharp-shooting Kate Bishop in the "Hawkeye" series fronted by Jeremy Renner. While her name was missing from Marvel's recent livestream reveal, it's not completely impossible for her to be added to the roster especially after studio head Kevin Feige confirmed the cast was not completed.

"Avengers: Doomsday", slated for release on May 1, 2026, provides an ideal platform to unite these emerging heroes against Doctor Doom's formidable threat. Robert Downey Jr. ditches his Iron Man persona to play a new character: Doctor Doom.

Key returning cast members include Patrick Stewart as Professor Charles Xavier, Ian McKellen as Magneto, Alan Cumming as Nightcrawler, Rebecca Romijn as Mystique, James Marsden as Cyclops, Channing Tatum as Gambit, and Kelsey Grammer as Beast.

For now, fans can only speculate and await further updates on whether Hailee Steinfeld's Kate Bishop will return to the Marvel Cinematic Universe.
