Russos Say Downey’s Doctor Doom Is Distinct as They Detail Hybrid On‑Set and Digital Performance

Overview

• On Thursday the film’s co‑director Joe Russo told Empire that Robert Downey Jr.’s Doom has “zero similarities” to Tony Stark and that Downey performed on set with a digital layer added later.
• Russo described the approach as experimental, saying the on‑set acting gives the filmmakers a first pass and digital work lets them refine the character’s look and motion.
• Many fans and some cast comments remain unconvinced, driving persistent theories that Downey’s Doom could be a Tony Stark variant or otherwise narratively linked to Stark.
• Marvel is tightly managing promotion after D23 special looks and unverified August leaks, and the studio has treated some online images as unconfirmed or possibly manipulated.
• The studio is positioning Avengers: Endgame — Encore as important background for Avengers: Doomsday and the latter is scheduled to open in theaters on December 18, 2026.
