Anthony Mackie, Harrison Ford, Danny Ramirez and more lead the cast of Marvel's newest movie, 'Captain America: Brave New World.'

The fourth "Captain America" movie, starring Anthony Mackie as Sam Wilson, has one end-credits scene that alludes to the future of the MCU.

Despite building up some anticipation for what’s to come, “Captain America: Brave New World’s” post-credits scene plays its cards close to the vest. The sole scene, which arrives after the full credits roll, sees Wilson visit Samuel Sterns (Tim Blake Nelson) at the Raft, a maximum-security prison for superpowered beings.
