The second film in the MCU has rarely factored into the universe as a whole, beyond William Hurt’s Thaddeus “Thunderbolt” Ross making recurring appearances in later films. That changes with Captain America: Brave New World, which will see Liv Tyler and Tim Blake Nelson reprise their roles as Betty Ross and Samuel Sterns/Leader, respectively.

“Captain America: The First Avenger” is foundational to the Captain America character. It’s here where you meet Steve Rogers (Chris Evans) and learn about the Super Soldier Serum that made him Captain America. You also gain an understanding of the type of values he holds, what he symbolizes and why he is “one of the best,” according to GameRant.
