Avengers: Endgame comes out on April 26 (that’s less than two weeks away!) and a lot of people are going to go see it; the President of Fandango, a company that sells movie tickets in advance, said that they’ve already sold millions, and that was over a week ago. Whether you’re a fan of superhero movies or not, it’s hard to deny that this movie will have a big audience. And because Endgame is the 22nd movie in the Marvel Studios franchise, people are wondering how to prepare for its release.

The great, late Marvel writer Stan Lee had a saying: “Every comic book is someone’s first issue.” Meaning, every issue should – briefly and organically – explain who the main character was and what the story was about, so anyone could pick it up, understand it and enjoy it. Lee said what he said because he knew that serialized, long-form storytelling can get very confusing very quickly when you don’t try to get the audience up to speed. When writers and editors forgot that was when comics became inaccessible for everyone who wasn’t currently reading them.

While the first few Marvel movies were accessible to general audiences, we are now on the 22nd movie in the franchise and there’s a huge chance that someone who had never seen a Marvel movie would walk into Endgame and be very confused for three hours and two minutes. Some, like the directors of Endgame have recommended, are watching all twenty-one Marvel movies before April 26, having started earlier this month and doing a movie per day. Others are, more practically, trying to figure out which movies are the most important ones, so they don’t have to sit through over 44 hours of content.

Before watching Endgame, you’ll want to know who the Avengers, Captain Marvel and Thanos are, what the Infinity Stones are, what the quantum realm is and what happened at the end of Infinity War. You can always google the answers to those questions – there are a lot of great resources online – but if you want to cram for Endgame the fun way and watch some movies instead of researching, I do have some suggestions.

Avengers: Endgame is the fourth Avengers movie, so the obvious thing to do would be to watch Avengers, Avengers: Age of Ultron and Avengers: Infinity War. However, even if you watch all three of those two-hour movies, you still might not be prepared for Endgame, because the events of Guardians of the Galaxy are pretty important as well. So is Captain Marvel and Ant-Man and the Wasp. You can probably skip Age of Ultron, but the rest of those movies contain the answers to those previously asked questions. Watch them and you can go into Endgame ready to enjoy the highly anticipated flick without any anxiety about being confused.
