A familiar speech
Captain America might not be the deepest movie series ever made, even in the MCU universe. It’s an action movie, so you wouldn’t expect there to be too many feel-good moments. However, the film franchise tends to touch upon themes of honor and tradition. There’s no better example of this than when Sharon Carter delivers a speech in Captain America: Civil War. However, this speech went over the heads of many fans.
While Sharon is delivering her speech, only the most hardcore comic fans would know that her script was taken word-for-for from the Civil War comics. This goes to show that you need to read the comics to truly appreciate the tiniest details.
