Avengers: Endgame - 33 Easter Eggs & References Explained

6. All The Iron Man Callbacks

Given that Endgame is the ultimate farewell to the Tony Stark character, it's fitting that the film includes a ton of references both visual and verbal to the original Iron Man.

Most obviously, Stark's final words in the movie are "I am Iron Man", just as they were in the first Iron Man movie, the original arc reactor gifted to Tony by Pepper (with the inscription, "Proof that Tony Stark has a heart") appears on his funeral float, and Happy Hogan (Jon Favreau) tells Morgan that Tony loved cheeseburgers (as was his snack of choice after being rescued from Afghanistan).

And if you stick around until the very end of Endgame's credits, you'll also hear metal repeatedly clanging together, in what's clearly a nod to Tony Stark smithing his prototype Iron Man suit in the Afghan cave.
