Watch: "Avengers: Endgame" Stars Get Silly for 3 Minutes Straight
Every hero has their own story and each story is worth telling.
A decade ago, six superheroes came together to take on an alien invasion, a mischievous brother and, sometimes, each other in a little movie called The Avengers. Little did we know what was to come: One snap from Thanos, three hit Disney+ TV series and billions of dollars. And now, Phase 4 of the Marvel Cinematic Universe is well underway, with Shang-Chi and the Legend of the Ten Rings introducing MCU fans to a new superhero played by Simu Liu, who all but manifested his Marvel introduction in a tweet several years ago when he publicly put his name in the ring—see what we did there?—for the job.
In honor of Shang-Chi's release on Sept. 3, we're revealing the surprising origin story for Liu and the rest of Marvel's biggest stars—Robert Downey Jr., Tom Holland, Brie Larson and more—including how they were cast and who else was up for the role.
