Robert Downey Jr. and Pedro Pascal have generated significant buzz this Halloween by swapping their respective characters for the upcoming film Avengers: Doomsday. While Downey Jr. is set to portray Victor von Doom in the movie, he appeared on social media dressed as Reed Richards in a retro-themed blue Mister Fantastic costume. Conversely, Pascal, who plays the superhero, donned Doctor Doom's iconic metal mask, pairing it with casual jeans and a sweatshirt rather than a full magical ensemble.
The actors shared videos of their night online, with Downey Jr. posting footage that quickly gained traction on Marvel feeds. Despite the simplified nature of Pascal's outfit compared to Downey's detailed costume, the visual impact of the role reversal was clear. This event serves as a promotional highlight just weeks before the film's premiere on December 18, 2026, which is described as marking the beginning of the end for this chapter of the Marvel Cinematic Universe.
Beyond the social media posts, the pair took their costumes to the streets to interact with children. Pascal shared an Instagram story showing them walking through crowds to greet trick-or-treaters. Additionally, X user Patrick Oneill documented an encounter where Downey Jr. and Pascal met two children dressed in Star Wars attire. When one child appeared as the Mandalorian, a character played by Pascal, Downey reportedly joked about inviting them to meet the "real" version of the character.
Avengers: Doomsday will feature a cameo from Sandra Hüller, known for Project Hail Mary, and marks the final on-screen appearance of Sir Patrick Stewart. The film's marketing has also included recent posters highlighting Doctor Doom alongside his three Latverian witches.
