Anthony Mackie officially stepped into the role of the first Black Captain America in "Captain America: Brave New World."

Anthony Mackie taking on the role of Captain America, a fictional comic book character initially portrayed as a white man with blond hair and blue eyes, isn’t groundbreaking to comic books fans.

Brave New World, which opened in theaters Friday, features Mackie as the titular superhero, marking his first starring film in the role. Mackie originally played Sam Wilson, aka Falcon, in the Marvel Cinematic Universe.

Anthony Mackie stopped by the AMC theater at Disney Springs inside Walt Disney World to drop in on an audience getting ready to watch his first big-screen performance as the new Captain America. The fun and exciting moment was captured in a video that was posted to Instagram.
