Robert Downey Jr. and Pedro Pascal spent Halloween in each other’s Avengers: Doomsday roles. Downey dressed as Pascal’s Mister Fantastic and Pascal as Downey’s Doctor Doom, a few weeks before the film reaches cinemas. Downey posted the result as a video on Instagram.
Deadline reports that Downey captioned the clip “Costume swap!” on Instagram. The effort wasn’t evenly split. Yahoo Entertainment describes Downey’s blue suit as carrying the Fantastic Four’s number four emblem across the chest, while Pascal wore a silver Doctor Doom mask and green hooded cape over a dark MIT crewneck sweatshirt, with jeans underneath. A full Doom getup would be hard to improvise, so Pascal’s half-and-half look makes sense.
The pair didn’t keep it to the camera. IGN reports that they went out in costume to meet trick-or-treaters, and that Pascal shared a video of the walk on his Instagram story. IGN also reports that a fan posted photos with two children in Star Wars costumes. One was dressed as Pascal’s Mandalorian, and Downey reportedly joked that they should come and meet the “real” Mandalorian.
The costume swap also spread on X, where fans circulated it within hours.
The swap is a joke, but the roles are real. In the film, the multiverse collapses and heroes from multiple Earths unite against Doctor Doom, played by Downey, with Pascal returning as Mister Fantastic alongside Vanessa Kirby, Joseph Quinn and Ebon Moss-Bachrach. So the gag only works because the two are cast as opponents, which is why fans have enjoyed it. Marvel’s own Doom push has been steady, from the CinemaCon footage to the first proper trailer, and our readers have also picked over theories about two Doctor Dooms.
