Yes, there are over 30 MCU movies but years later, 2014's "Captain America: The Winter Soldier" remains one of the best. The story finds Steve Rogers (Chris Evans) in a spy thriller that ultimately shakes the US government to its core. Joining him are Scarlett Johansson as the Black Widow and Sebastian Stan as Bucky (aka the titular Winter Soldier). Anthony Mackie also debuted as Sam Wilson in the movie. Also on board is legendary actor Robert Redford as a S.H.I.E.L.D. head with a lot to hide.
