In addition to Michael Rooker lending his pipes to the much-anticipated show, What If? … will also feature the voice talents of Mark Ruffalo, Hayley Atwell, Natalie Portman, Jeremy Renner, Paul Rudd, Taika Waititi, Chris Hemsworth, Tom Hiddleston, Samuel L. Jackson, Michael B. Jordan, Karen Gillan, Josh Brolin, Jeff Goldblum, Frank Grillo, Dominic Cooper, Sean Gunn, Sebastian Stan, and the late Chadwick Boseman, to name only a few famous names attached. Additionally, there’s a possibility that Robert Downey Jr., Chris Evans, Brie Larson, and Benedict Cumberbatch will be heard in their respective Marvel parts, though their voice roles haven’t been confirmed at this time.
We’ll learn more about this animated series in the months ahead, but this performance could prove to be bittersweet if it’s truly the last time we hear Michel Rooker as Yondu. Admittedly, the actor cheekily expressed openness in reprising this role, so maybe he’ll come back someday. For now, though, this is Rooker’s last confirmed MCU appearance.
