The latest trailer for 'Avengers: Doomsday,' released on July 20, 2026, features Robert Downey Jr. as Doctor Doom, with a voice that has drawn comparisons to the character Nandor the Relentless from 'What We Do in the Shadows.' The trailer, which premiered at San Diego Comic-Con, shows Downey's Doom speaking in a deep, accented tone, but the exact nature of the voice has not been officially confirmed by Marvel Studios.
Fans have noted that the voice differs from previous portrayals of Doctor Doom in other Marvel films, such as those by Julian McMahon in the 2005 'Fantastic Four' or Toby Kebbell in the 2015 reboot. The choice has sparked speculation about whether this is a deliberate creative decision or a temporary effect for the trailer.
As of July 21, 2026, Marvel has not released additional details about the voice or the plot of 'Avengers: Doomsday,' which is scheduled for release on May 1, 2027. The film is directed by the Russo brothers and is expected to be a major crossover event in the Marvel Cinematic Universe.
