We asked the BuzzFeed Community to tell us their favorite callbacks in the Marvel Cinematic Universe and compiled all the best callbacks in Endgame. Now here are some of the best non-Endgame callbacks:
🚨 Spoilers ahead! 🚨 Also, not all submissions are from Community users.
1. A Stark-designed ship in Thor: Ragnarok requires that Thor use the name "Point Break," a reference to Tony using the nickname in The Avengers.

2. A case described in Doctor Strange seems to match Justin Hammer's failed attempt at re-creating Iron Man in Iron Man 2.

3. Marvel Cinematic Universe TV shows have a running joke of messing up that famous Spider-Man quote, "With great power comes great responsibility."

4. Captain Marvel teases people who saw Captain America: The Winter Soldier by implying Fury will lose his eye by trusting a Coulson lookalike, only for him to actually lose his eye by petting a cat.

5. Captain America references his catchphrase from Captain America: The First Avenger in Captain America: Civil War.

6. In Spider-Man: Far From Home, Happy turns on "Back in Black," the song that the Jon Favreau-directed Iron Man opens with, but Peter Parker is too young to recognize who it's by.

7. In Agent Carter, we meet the Stark Labs scientist Anton Vanko, who we learned in Iron Man 2 helped create Stark's arc reactor technology and also fathered Ivan Vanko, aka Whiplash.

8. In Infinity War, Loki makes a reference to something Tony said to him all the way back in The Avengers, making it clear he's really switched sides.

9. Both Spider-Man: Homecoming and Spider-Man: Far From Home end with a cutoff "What the f—?"

10. Black Panther's UN speech scene parallels the press conference at the end of Iron Man.

11. Loki cheering when Hulk smashes Thor in Thor: Ragnarok is a reference to Loki getting similarly smashed in The Avengers.

12. In The Incredible Hulk, we meet a pizza-craving grad student who grows up to become Peter Parker's teacher.

13. Captain America: The Winter Soldier mentions Stephen Strange as a target of Project Insight two years before the release of Doctor Strange.

14. Thor's failed attempt to soothe Hulk in Thor: Ragnarok is a reference to what Natasha does to soothe Hulk in Avengers: Age of Ultron.

15. In Spider-Man: Far From Home, Peter unknowingly mimics the way Tony interacts with holograms in Iron Man, which gets him a fond look from Happy.

16. A map in a S.H.I.E.L.D. facility in Iron Man 2 seems to label significant places in both past and future MCU movies.

17. Agents of S.H.I.E.L.D. references Wolfgang von Strucker and the fact that he gave Scarlet Witch and Quicksilver their powers, which we saw in the credits of Captain America: The Winter Soldier.

18. The first episode of Agents of S.H.I.E.L.D. casually mentions Project Pegasus, which we later find out was the secret Tesseract experiment that gave Captain Marvel her powers.

19. Captain Marvel explains how Fury came up with the Avengers Initiative presented in Iron Man 2, as well as where the name Avengers came from.

20. And finally, the MCU starts with Tony saying "I am Iron Man" at the end of Iron Man, so it's fitting that MCU's Phase Three ends with "Spider-Man's name is Peter Parker" in Spider-Man: Far From Home.
