Whether you're a hardcore fan of the Marvel Cinematic Universe or just recently discovered the expansive franchise, here's everything you need to know about  what has happened to be prepared for Avengers: Endgame. Marvel Studios launched the MCU in 2008 with the release of Iron Man and The Incredible Hulk in the span of two months. Since this point, the universe has grown beyond what anyone - other than Kevin Feige - likely imagined.

The last 11 years and 21 movies have all been part of one continuous story that has been leading to Avengers: Endgame. Judging by the popularity of the MCU films, it is difficult to imagine that there are people out there who aren't seeing these movies on opening weekend. But, the box office of these movies continues to grow, which does indicate that new fans continue to come aboard. Just look at the billion dollar successes of Black Panther and Captain Marvel.

As the fan base has grown, so has the continuity and canon that they must try to keep up with. This can be difficult, though, especially if fans don't make time to do rewatches of past films before the newest ones, so Screen Rant is here to help you out. In our new video, we take a look at everything that has happened in the MCU and condense it down into one simple and informative watch. Check it out at the top of this post.

The lengthy continuity that is building towards Avengers: Endgame will give viewers a better understanding of the world and the remaining characters, but it could also be extra beneficial here. It is largely expected that Avengers: Endgame will feature time travel in some way, and many believe that the movie may use this to revisit past MCU events. If this is does happen, then knowing what happened in these moments before will likely help viewers understand the significance of what is going on and even catch additional Easter eggs that may be included.

That all said, there is also the hope that Marvel Studios and directors Anthony and Joe Russo managed to craft Avengers: Endgame in a way where it is still a somewhat digestible film for casual fans, or maybe even someone who hasn't seen any of the prior MCU films. That may be an impossible task considering how much Avengers: Endgame is building off of Avengers: Infinity War's ending and past MCU films though. If you are hoping to gain a deeper understanding of what Avengers: Endgame will be, watching these five essential MCU films is the best place to start.
