The Russo Brothers revealed at San Diego Comic-Con that their attention is currently divided between wrapping post-production on Avengers: Doomsday and beginning preparatory work on its sequel, Avengers: Secret Wars. Anthony Russo described the period as demanding but energising, highlighting their involvement in final audio mixing and collaboration with composer Alan Silvestri on the first film's score.

Whilst the directors acknowledged that Secret Wars groundwork is already underway behind the scenes, the interview provided no concrete filming dates, production schedules, or release timeline—despite the headline's suggestion otherwise. The update amounts to confirmation that both films are in active development with overlapping production phases, but specifics about when Secret Wars principal photography will begin remain undisclosed.
