The Marvel Cinematic Universe remains a world-dominating entertainment phenomenon, and with good reason. Fans want more than just films: they want to go behind the scenes of Marvel movies to dig up facts about the MCU to further their immersion in the world of The Avengers and Guardians of the Galaxy. Plenty of Marvel movie trivia already exists, but this Marvel Universe trivia delves into the insane detail producers put into this franchise. Unlike MCU fan theories, these fun MCU tidbits come straight from the series's source: the writers and producers. Even the most veteran and expert fans of the MCU still finds things they didn’t know about Marvel movies, and the hunt for more and more trivial tidbits can be nearly as exciting as a quest for Infinity Stones. 


The Marvel Cinematic Universe began in 2008 with the release of Iron Man, and shows no signs of slowing when it comes to taking over Hollywood. The MCU now pumps out three blockbuster films per year, along with several television series, and recently Marvel Studios gained access to even more characters with Disney’s acquisition of Fox, which means you can catch all your favorite Marvel movies, series, and spinoffs on Disney+. The MCU already reads so well, but if producers continue with this attention to detail, its future looks to be even more spectacular!

    Throughout the entirety of Captain America: The Winter Soldier, fans witness Steve Rogers adjusting to a world that aged without him. To help himself acclimate, Cap keeps a running list of things he needs to catch up on, like Nirvana, Star Wars, and the Troubleman soundtrack. However, that’s just the list that North American audiences got to see. The list appears differently in other markets, thereby making the references more relevant for fans all over the world. In the UK, Cap needs to check out Sean Connery and the 1966 World Cup Final, while in Russia he’s tasked with reviewing Yuri Gargarin and the dissolution of the Soviet Union, and so on and so forth. Talk about a committed soldier.

    Chadwick Boseman, an American actor, developed a Wakandan accent for his role as the Black Panther, an accent that sounds rich, intimidating, and believable. It probably helps that he’s not making the language up completely from scratch. Other fictional universes, like that of Avatar, created entire languages for their characters to speak. Instead of going down such a tedious route, Marvel Studios decided to use the real-world language of Xhosa as a stand-in for the fictional Wakandan dialect. Xhosa is an official language of South Africa, the homeland of John Kani, the actor portraying T’Chaka, though it is not widely spoken there.

    Same as any other movies, the films of the Marvel Cinematic Universe each have a few deleted scenes available for viewing as Blu-Ray bonus features. However, none of these deleted scenes get anywhere near as dark as one from The Incredible Hulk. The sequence, originally intended to open the film, featured Bruce Banner traveling to the far north, where he intends to commit suicide via a gunshot to the head. Before he can complete his task, Banner “Hulks out” and crushes the gun. Later, this moment is referenced in The Avengers when Banner says, “I put a bullet in my mouth and the other guy spit it out.”

    Phil Coulson, unofficial Avenger, stands as one of the greatest heroes of the Marvel Cinematic Universe. He also wasn’t originally intended to be much of a character at all. In the original script for Iron Man, the character of Coulson was referred to simply as “Agent,” and Clark Gregg almost dropped out of the film over worries his part would be greatly overshadowed. However, Gregg used his trademark charm to impress everyone on set, leading to a bigger role in Iron Man. After that, the filmmakers behind Thor requested Coulson for their film, and the rest is history.
