🚨Warning: There are MASSIVE — and I mean massive — spoilers ahead for Spider-Man: No Way Home!🚨
1. First, in the opening minutes of the film when Peter and MJ are swinging through NYC, you can spot two posters for Rogers: The Musical, which was first introduced in Hawkeye.
2. Peter and MJ briefly stop on top of the Queensboro Bridge after his identity is revealed, and in Spider-Man, Green Goblin notoriously dropped MJ from this exact bridge.
3. When Peter and MJ pop out of the sewer while swinging back to Peter's apartment, they stop in front of Delmar's deli, which was featured in Spider-Man: Homecoming.
4. Damage Control shows up at Peter and Aunt May's apartment shortly after his identity is revealed. In Spider-Man: Homecoming, we learned about how this agency is the reason Adrian Toomes lost his job following the Battle of New York.
5. When MJ is being interrogated at the police station, it's the first time we learn her real last name. Up until this point, we've only heard her referred to as "Michelle Jones," but now we know her full name is "Michelle Jones-Watson."
6. While Matt Murdock's appearance in Spider-Man: No Way Home isn't a hidden detail, it is a nod to an issue of The Amazing Spider-Man when Peter is arrested and is represented by Matt.
7. Inside Happy's apartment, you can spot a Downton Abbey DVD, which we learned was Happy's favorite show after Tony mentioned it in Iron Man 3.
8. Protestors outside Peter's school are holding several signs that refer to Spider-Man as the devil, and, not to go all Mephisto on us, but in the Spider-Man: One More Day seven-issue comic run, Peter makes a deal with Mephisto to bring back Aunt May.
9. When Betty Brant is giving her newscast outside of the school, she tells Peter to "go get 'em, tiger," which was also said by MJ at the end of Spider-Man 2.
10. When Peter is talking to his teachers at school, there is a mural of famous scientists, innovators, etc. behind him. If you look closely, you can spot Howard Stark and Hank Pym.
11. When Peter, MJ, and Ned are hanging on the roof between classes, you can spot some graffiti reading "DITKO" on the wall behind them. This is a nod to Steve Ditko, a comic book artist who co-created Spider-Man.
12. When Peter visits Doctor Strange and asks for his help, you can see he's wearing a Columbia University sweatshirt. In the comics, that's the college Doctor Strange attended too.
13. During Doctor Strange's spell, Peter continues to add to the list of people he wants to make sure DO remember him. This is similar to a storyline in The Amazing Spider-Man comics where Peter asks Doctor Strange if everyone can forget except for MJ.
14. When Aunt May and Peter are opening his college acceptance letters, you can see that he's building a Lego Death Star from Star Wars with DUM-E. This is a callback to Spider-Man: Homecoming when Ned destroys his Death Star after finding out Peter is Spider-Man.
15. When Peter is walking down the highway to try and catch up to the MIT vice chancellor, you can see the license plate on her car reads "63ASM-3," which is a nod to The Amazing Spider-Man Issue #3, which was released in 1963.
16. And speaking of license plates, the taxi behind the vice chancellor's car has a license plate that reads "1228," which is a nod to Stan Lee's birthday, Dec. 28.
17. When the teaser trailer dropped for Spider-Man: No Way Home, people thought that the Peter in the suit on top of the car was actually Tobey Maguire's Peter. While that turned out to be false, the suit is a nod to Spider-Man 3.
18. When Doc Ock first arrives and confronts Peter, he says, "The power of the sun in the palm of my hand," which is the same thing he said in Spider-Man 2 right before he was turned into Doc Ock for the first time.
19. When MJ, Peter, and Ned are working in Doctor Strange's basement, MJ picks up a box for a goatee template, which is just hilarious.
20. When Peter goes out to find Electro and Sandman, he's wearing a black and gold Spider-Man suit, which is his suit turned inside out. This was previously referenced in Spider-Man: Homecoming when Peter removed Tony's tracking chip.
21. In the movie, we see that Aunt May works at F.E.A.S.T., which is a homeless shelter taken directly from the Marvel's Spider-Man video games. In the games, Miles Morales also volunteers there.
22. Norman Osborn brilliantly says the line, “You know, I’m something of a scientist myself" when he's trapped in the "wizard's dungeon" with the rest of the villains. This quote is a nod to Spider-Man, where he says the exact same thing to Peter.
23. When Peter is trying to steal the rogue spell from Doctor Strange, he briefly wears Doctor Strange's cape, which not only happened in What If...? Episode 5, but in the comics as well.
24. At the same time, Doctor Strange walks past a newsstand where you can see Liz Toomes, Peter's girlfriend from Spider-Man: Homecoming, on the cover of People Magazine with the quote, "He's a liar."
25. When Aunt May low-key flirts with Doc Ock and asks what kind of water he wants, it relates to the comics, where Aunt May and Dr. Otto Octavius date for a brief period. To be fair, Marisa Tomei has chemistry with everyone.
26. When Aunt May is dying, she utters, "With great power there must also come great responsibility," which is a heartbreaking callback to Uncle Ben in Spider-Man.
27. Ned learns that Tobey's Peter dealt with his best friend, Harry, betraying him and then dying, and Ned looks worried. Sadly, this is a nod to Ned's comic book trajectory, where he is thought to be Hobgoblin.
28. The absolutely iconic meme of the Spider-Men pointing at each other is re-created twice in this movie by Andrew Garfield, Tom Holland, and Tobey. Once when they are inside the science classroom and Ned calls their names, and then again when they are figuring out how to work together at the Statue of Liberty.
29. While preparing to fight all of the villains, Andrew's Peter adorably cracks Tobey's Peter's back after he talks about how it bothers him. It's a funny moment that is actually a callback to Spider-Man 2 when Peter hurt his back after jumping off a building.
30. When the three Peters are chatting, Tobey's Peter calls Andrew's Peter "amazing," which is an on-the-nose nod to Andrew's films being called The Amazing Spider-Man and The Amazing Spider-Man 2.
31. Tobey's Peter mentions that he fought an "alien made out of black goo," which is a reference to Spider-Man 3, where he fought Venom.
32. Tom's Peter hilariously tries to explain who The Avengers are to the other Peters, and he says "Earth's mightiest" before Tobey's Peter cuts him off. This is a nod to the Marvel comics, where The Avengers slogan is "Earth's Mightiest Heroes."
33. When Electro meets the Peters at the Statue of Liberty, he's now rocking a suit that closely mirrors his look from the Marvel comics.
34. Andrew's Peter reluctantly takes the codename "Peter three," which could honestly be a nod to the fact that, for years, Andrew's portrayal of Spider-Man was notoriously ranked last after Tobey and Tom's.
35. When Doctor Strange eventually returns from the Mirror Dimension, he says he was dangling over the Grand Canyon for 12 hours, similar to how he left Loki falling in Thor: Ragnarok.
36. When Andrew's Spider-Man is unmasked, Electro says he always imagined Spider-Man as a Black man and there has got to be a Black Spider-Man out there somewhere. This is a perfect nod to Miles Morales, who we've met in Spider-Man: Into the Spider-Verse.
37. The most heartbreaking callback in No Way Home is when Andrew's Peter is able to save MJ after she falls off the Statue of Liberty. This is something he wasn't able to do in Amazing Spider-Man 2, when Gwen tragically fell to her death.
38. When the multiverse begins to crack open, you can spot the silhouettes of Rhino and Scorpion in the sky. Both are famous Spider-Man villains who we've previously seen iterations of in the live-action movies.
39. The world forgetting Peter Parker also happened at the end of the Spider-Man: One More Day comic book run. In the comic, Peter and MJ trade their memories of their wedding and life together to Mephisto in an attempt to bring back Aunt May.
41. When Peter goes to see MJ after her memory is erased, you can see that she's still wearing the broken black dahlia necklace Peter gave her in Spider-Man: Far From Home.
42. When Peter is moving into his new apartment, he places a Lego figure of Palpatine from Star Wars on his desk. This figure was featured in Spider-Man: Homecoming when Ned invites Peter to build a Lego Death Star with him.
43. And finally, Peter's new suit at the very end of Spider-Man: No Way Home is a nod to the classic Spider-Man suit from the comics, complete with the vibrant blue and red.
