10 Superhero Movies That Defined Other Superhero Movies

10. Captain America: The First Avenger 

Steve Rogers' MCU debut took place towards the end of Phase One in what is perhaps the shared universe's most underrated film. Captain America: The First Avenger flashed back to the days of World War II in order to introduce us to the Star-Spangled Man and, from that moment on, the MCU had its most patriotic hero.

With that in mind, you'd be hard-pressed to find anyone that would disagree that this film didn't play a large part in inspiring Warner Bros. to produce Wonder Woman.

From the structure (a present-day object initiating the flashbacks) to the period setting, and let's not forget the fact that both heroes managed to find love in a hopeless environment, it's clear that the DCEU's most beloved film borrowed a lot from the successful formula that Marvel employed for Cap's origin story.

While it's true that much of Wonder Woman's source material was set during the wars, and the fact that the classic '70s TV series found success in a period setting, there is no denying that it owes a lot to the success of Captain America: The First Avenger.
