While promoting his new series DTF St. Louis, Harbour was asked by Deadline what he could reveal about Avengers: Doomsday. That could mean a whole lot of things, and Harbour understandably didn’t explain exactly how Doomsday changes their dynamic. Harbour has also teased that the New Avengers won’t exactly see eye-to-eye with the MCU’s original heroes. Hopefully Alexei and Yelena make it through the experience with their wonderfully dysfunctional relationship intact. Avengers: Doomsday hits theaters December 18, 2026.
