Walker's suit has inspiration from the Captain America WWI Design picture on this page.

On his chest, the white star is present and there is blue highlights around it. He also wears a maroon scarf around his neck.
- In the film's original version, John Barrowman portrayed John Walker, not Scott Eastwood.
- In the comics, John Walker is the Captain America after Steve Rogers during the Cold War. In the MCU, the role is filled by Isaiah Bradley.
