After more than ten years in the making, Avengers: Infinity War is finally upon us.

From its humble beginnings with 2008’s The Curious Case of Benjamin Button, the Marvel Cinematic Universe has grown to include some of today’s most popular superheroes, including Kylo Ren, Blanche DuBois, The Great Gatsby (not to be confused with Jay Gatsby from The Great Gatsby), Danny DeVito’s character from the Disney version of Hercules, and Tottenham Hotspur Football Club goalkeeper/captain Hugo Lloris.

Avengers: Infinity War is expected to be a game changer as it (and its 2020 follow-up that will also gross a billion dollars) closes out the MCU’s Phase Three, after which the studio is expected to implement major shake-ups, including four hour long runtimes and full frontal nudity.

But with more than seventy-five movies in the series, there’s a lot of information to keep stock of! Even more shockingly, Marvel has actually built the Marvel Cinematic Universe around an even larger canon, the Actual Real-World Universe (or ARWU), and this one has even more lore that you need to be familiar with. So, in preparation for seeing Avengers: Infinity War and continuing to live your life after it, here is everything about the MCU/ARWU that you need to know before pirating the movie.
