Spider-Man: Homecoming is hands-down the best Spider-Man film, which is not surprising as the Webslinger is now in the very capable hands of Marvel Studios. And of course, like all comic book movies, there is no shortage of Easter eggs in Spider-Man: Homecoming. And the references are not just to the source material, but to the larger MCU, and there are even a couple references to the previous Spidey movies.
Now that your friendly neighborhood Spider-Man has been added to the MCU, they've got some catching up to do in terms of fully integrating him. While it might seem a little heavy-handed at the outset, Homecoming quickly figures out how to balance a solo Spider-Man film while still flawlessly connecting his story to the larger universe. And it is flawless.
Take a look at the most noteworthy Spider-Man: Homecoming Easter eggs. Oh, and, just so you know, Stan Lee isn't in here. Because that one's a bit on the nose.
Dr. Bruce Banner
An even more notable scientist makes a brief appearance as well in Peter's classroom. Or at least a picture of him does. Above the whiteboard at the front of the room are portraits of notable scientists, and the very last one is the guy that turns into a giant green rage monster.
Megawhoosawhat?! Megingjörð. You know, Thor's magic belt. Happy Hogan is transporting some high-value items via cargo plane in Homecoming, and double checks to see if "Meg-- Meg-- Thor's magic belt" is on board. This belt has the power to double Thor's strength. So it's kind of a big deal.
Karen, Peter's J.A.R.V.I.S.
Once Ned disables the "Training Wheels Protocol" from Peter's suit, he discovers that it has an AI just like Tony's Iron Man suits. Pete hilariously dubs his AI Karen, who is voiced by Jennifer Connelly. Why is this interesting? Because in real life she's married to Paul Bettany, who of course voiced J.A.R.V.I.S. and now plays the Vision.
Lifting The Debris
Pete's climactic fight with the Vulture doesn't get off to a great start. The Vulture tricks him, bringing half a building down on poor little Spider-Man, burying him in debris. As Spidey struggles, he begins to lose faith. But then he's sees his mask floating in some water, reflecting half of his face, the other half covered by the mask. There are actually two comic references here. First of all, the half and half Spidey face is a common technique used in the source material, usually to depict when his Spidey Sense is tingling (although in the movie, it's a thematic and symbolic point about Peter being a hero, regardless of the suit and powers).
The other reference in this scene is actually the debris itself. Peter being buried under debris and having to lift it is a recreation of a scene from 1966 in Amazing Spider-Man #33.
