8. The First Comic
Captain America: The First Avenger is very much a celebration of the character’s comic history, to the point where the film makes a couple of references to Captain America #1, originally published in 1941. In the film, the comic actually shows up, the difference being that in real life the movie was inspired by the comic book, while the comic book shown in the film is inspired by the “real” Captain America. Additionally, we also see Cap punch a man dressed up as Adolf Hitler during the film’s stage show sequence, an imitation of the first issue’s cover.

7. The Story of Sgt. John Basilone
In The First Avenger, Captain America begins his career as the United States Army’s stateside symbol of patriotism in an effort to sell war bonds, much to his own personal frustration. This story actually mirrors the real life experience of World War II hero Sgt. John Basilone of the Marine Corps. Basilone was awarded the Medal of Honor for his displays of heroism in combat at Guadalcanal, and was subsequently sent back to the States to help raise money for the war effort. Understandably frustrated that he was no longer fighting alongside his countrymen, Basilone requested that he be sent back overseas. Sadly, he was killed in action at Iwo Jima, but took out a sizable group of enemies in the process.
