1. The final battle in Black Panther takes place on a literal underground railroad.
2. There are a lot of visual similarities to The Lion King.
3. The self-lacing shoes Shuri creates for T'Challa are a reference to the self-lacing shoes in Back to the Future Part II.
4. When Shuri screamed, "WHAT ARE THOOOOSE?!" — yeah, that was a reference to this iconic Vine video (and eventual meme):
5. And it turns out those sandals that Shuri makes fun of are actually Alexander McQueen shoes!
6. Also, when Shuri calls Everett "another broken white boy for us to fix" she's referring to Bucky Barnes.
7. And, in the second post-credit sequence of Black Panther, when the children call Bucky Barnes the “White Wolf," this is a reference to T’Challa’s adopted brother in the comics.
9. Stan Lee's credit in this film was "Thirsty Gambler."
10. Ryan Coogler explained that James Bond actually had a pretty strong influence on the film.
11. T’Challa throwing himself on a grenade is a callback to a similar sequence in Captain America: The First Avenger.
12. Shuri’s lab is on "Mount Bashenga," which is named after the first Black Panther (from thousands of years ago).
13. T’Challa’s fight with M’Baku took place at dawn (symbolizing a new beginning), while his fight with Killmonger happened at sunset (symbolizing his downfall).
14. Killmonger says his allies are in London, New York, and Hong Kong...which happen to be the same cities where Doctor Strange has sanctums.
15. At one point, Shuri wears her hair in two buns, a nod to fellow Disney princess, Princess Leia's look in A New Hope.
16. When T'Challa, Okoye, and Nakia are in the casino, they're wearing red, black, and green — i.e. the colors of the Pan-African flag.
17. Donald Glover is mentioned in the end credits because he gave Ryan Coogler notes on the script.
18. Black Panther's cinematographer, Rachel Morrison, is the first female director of photography to receive an Oscar nomination (for Mudbound).
19. Rapper Wale makes a brief cameo in the film.
20. It's hard to see, but during the interrogation of Ulysses (Andy Serkis), it looks like a bearded Captain America appears on one of the screens in the background.
21. And finally, Killmonger and T'Challa cradled their respective dead fathers in a similar fashion.
