After 11 years and 22 movies, the Marvel Cinematic Universe culminated in the sprawling, powerful, three-hour epic Avengers: Endgame. Fans had plenty of time to debate their Infinity War theories and predict how Phase 4 of the MCU might begin. Anyone worried about SPOILERS should turn back now because this list is going to go into what happened to Earth's Mightiest Heroes.
In the end, how the Avengers finally beat Thanos is as exciting as it is heartbreaking. Not one but two heroes wear the Infinity Gauntlet in a "whatever it takes" effort to crush the Mad Titan and protect the universe from his megalomania. Between large-scale fights, time travel hijinks, and a pleasantly surprising amount of humor, it is easy to miss the dozens of little Avengers: Endgame Easter eggs and references crammed throughout the movie. There's some great stuff there, though, and those little moments really cement Endgame as the climax of a story more than a decade in the making.
Strap on your magical glove and skintight time travel suit and let's get to it. And when you're done, be sure to check out all of Endgame's plot holes.
Once Scott Lang escapes from his stint in the Quantum Realm, he faces the very real possibility he'll never escape from the storage facility in which his van is stored. Thankfully, a sympathetic security guard played by Ken Jeong helps him escape.
But before he does, the security guard puts down his book - The Terminal Beach. This book was published in 1964 and includes several short science fiction stories, including one titled End-Game.
During the scene where Captain America counsels Snap survivors in the basement of a church, we see a sign mentioning a certain Matthew Haggerty. That name doesn't mean much in the fictional world of the MCU, but it is important in the real world of Marvel Studios.
Haggerty was an assistant director on Infinity War and Endgame, and he even worked on the first Iron Man back in 2008.
As part of his disguise for the brief detour to the 1970s, Steve Rogers dons a soldier uniform with the name "Roscoe" on it. This is most likely a reference to the comic character Roscoe Simons, who takes up the Captain America mantle for a brief run in the mid-'70s when Steve puts down the shield to become Nomad.
This is more of a cameo for sports and fantasy football fanatics, but ESPN's senior fantasy analyst, Matthew Berry, shows up in 2012 New York as a personal bodyguard for secret Hydra member Alexander Pierce. He doesn't look as imposing as some of the other Hydra double-agents, but maybe he's just there to advise on whether Aaron Rodgers was worth a first round pick in Pierce's fantasy draft.
