When Marvel Studios’ first foray into animation — a series called What If…? — was announced, Marvel fans weren’t sure how many of their favorite MCU stars would return for the project. As it turns out, quite a few Avengers franchise actors decided to leap from live-action to the new animated series, which debuted on Disney+ on August 11, 2021.

Although the star-studded What If…? cast list features several fan-favorites, there are some notable missing names — Brie Larson (Carol Danvers/Captain Marvel), Tom Holland (Peter Parker/Spider-Man), and, of course, Robert Downey, Jr. (Tony Stark/Iron Man).

It is no secret that RDJ’s time in the MCU is over. On multiple occasions, the actor has previously confirmed that he has done “all I could” with the Iron Man character. Earlier this year, he even infamously unfollowed all of his Avengers costars on social media. Although this probably meant nothing, Marvel fans were up-in-arms about the move, which was likely orchestrated by Downey, Jr.’s management team as he moved his career away from the Marvel Cinematic Universe.

As fans know, Stark sacrificed himself in Avengers: Endgame (2019), cementing RDJ’s exit. Now, Marvel has given the first look at their recast Iron Man in a new What If…? trailer.
Although the series is animated, Stark still resembles Downey, Jr., a new voice actor behind the Stark Industries head. You can watch the trailer in full below:
