As Marvel Studios prepares to release Avengers: Doomsday on December 18, co-director Anthony Russo has opened up about the immense pressure of evolving iconic characters, balancing fan expectations, and the creative challenge of keeping both filmmakers and audiences genuinely surprised by the unfolding narrative.
Anthony Russo on evolving characters and casting Robert Downey Jr
- The Creative Balancing Act: Co-director Anthony Russo admits that evolving beloved Marvel characters is “very difficult,” requiring filmmakers to rely on their own creative meters while acknowledging that fandoms never speak with a single voice.
- A Monumental Casting Challenge: Bringing Robert Downey Jr. back to the MCU as Victor Von Doom—following his legendary, self-sacrificing exit as Tony Stark in Avengers: Endgame—represents one of the franchise’s greatest structural hurdles.
- Massive Ensemble Scale: Speaking during a Q&A following an Avengers: Endgame Encore screening, Russo noted that the massive ensemble cast is so large that even he occasionally loses track of who has been officially announced.
Understanding the Complex Psychology of Fandom
Returning to the world of the Marvel Cinematic Universe means wading into a vast ocean of passionate viewer expectations. Speaking at a Q&A following an Avengers: Endgame Encore screening in New York, Anthony Russo explained how he and his brother, co-director Joe Russo, approach the delicate task of moving established characters forward without alienating the people who have tracked their journeys for over a decade.
“It’s a very difficult part of the process because, I mean, we basically just have to use our own meters because we love the characters, we love the history, we love them in the same way that many fans do,” Russo told attendees, in coverage detailed by GamesRadar+ and Yahoo Entertainment. He emphasized that filmmakers must accept a core truth about modern blockbusters: “The one thing we always like to remind people of, you know, fandom does not speak with a single voice. There’s a wide variety of opinion in terms of who responds to which characters and which versions of which characters people respond to, it’s a very complex relationship that people have with the characters.”
Respecting History While Chasing Surprises
For the Russos, honoring the narrative road traveled by Earth’s Mightiest Heroes is non-negotiable. At the same time, stagnation remains the ultimate enemy of long-running franchise filmmaking. Striking that equilibrium demands a willingness to subvert expectations.

Russo noted that they hold “a lot of respect for the storytelling journey that these characters have had up to this point,” adding, “That’s part of their magic, a big part of their magic. But at the same time, we need to surprise ourselves in terms of who those characters are, where they can go, what they can do, what can happen, and in doing that, we hopefully surprise audiences as well.” This philosophy directly echoes stylistic shifts seen in recent promotional material, such as an Avengers: Doomsday trailer released nearly a year ago that spotlighted a significantly more serious Thor, played by Chris Hemsworth, steering away from the divisive, comedic tone seen in 2022’s Thor: Love and Thunder.
The Robert Downey Jr. Paradox and the Massive Ensemble Cast
Perhaps the most high-stakes gamble in Avengers: Doomsday involves reshaping the MCU’s foundational landscape by casting Robert Downey Jr. as the iconic villain Victor Von Doom. Following Tony Stark’s emotional sacrifice in Avengers: Endgame, reintegrating Downey into a leading antagonist role requires an immense narrative pivot.
Russo addressed this casting choice directly, explaining the necessity of balancing bold creative risks with established continuity. “It is figuring out that balance of how do you challenge yourself, i.e. casting Robert Downey as Victor Von Doom, and then and how do you sort of stay faithful to the very thoughtful and wonderfully effective storytelling road that’s been traveled up until this point,” Russo stated during the 92nd Street Y discussion.

Managing a production of this magnitude also brings logistical hurdles. Commenting on the sprawling roster of talent, Russo admitted that keeping track of the lineup is a challenge in its own right. “The cast is so large, and we’ve announced some of the cast, and we haven’t announced some of the cast,” Russo said. “I get confused myself over who we’ve announced and not announced, so I have to just slow down.” Alongside Downey and Hemsworth, the confirmed roster includes Chris Evans, Paul Rudd, Simu Liu, and Tom Hiddleston.
As the December 18 theatrical release approaches, the pressure on the Russos to deliver a unifying cinematic event remains extraordinarily high.
