When Shuri gives T'challa the new shoes (called sneakers), she mentions that they absorb sound & allow silent footsteps, which T'challa demonstrates. Later in the film, T'challa runs up a ramp wearing the sneakers... accompanied by the sound of footsteps.

Killmonger is said to have "graduated from Annapolis at 19". Annapolis refers to the United States Naval Academy in Annapolis, Maryland. They do not allow anyone younger than 17 to enroll, nor can you graduate early due to its rigid four-year academic program for its midshipmen.

Factual errors

When T'Challa is addressing the UN, a Welsh flag can be seen among the other flags in the background.

As a part of the United Kingdom, Wales doesn't have UN membership in its own right, so this flag would not be displayed.

Audio/visual unsynchronised

During the scene where Ulysses Klaue is being interrogated by Everett Ross, you continue to hear Klaue speak whilst the camera is shown outside the interrogation room, with the camera focused on T'Challa. When T'Challa begins to walk, you can see Klaue behind him and whilst you can hear him still talking, his lips aren't moving within the interrogation room in the background.

Continuity

During the duel between T'Challa and Killmonger, both repeatedly switch between wearing black trousers and black shorts, depending on the camera angle and the editing.

Continuity

After Killmonger wins the challenge against T'Challa, the leader of a tribe goes to put a necklace on Killmonger with shaking hands. In the first shot, she is holding a necklace with a short cord and a metal lobster claw clasp. When she puts the necklace on Killmonger, the necklace strand is much longer and made entirely of rope.

Incorrectly regarded as goofs

The opening sequence showing the Earth from space as the vibranium meteor crashes into Africa shows the modern globe, even though millions of years ago continents had noticeably different shapes and positions. However, the sequence clearly shows not a real Earth, but a representation of Earth in the imagination of the child who is listening to the story. It's obvious, since this imaginary Earth has neither oceans, nor atmosphere, nor vegetation.

Continuity

When Everett K. Ross enters the interrogation room he has the listening device on his left shoulder. When he leaves the interrogation room, it has vanished. But when the scene cuts to a different camera angle, you can see the listening device again (it is out of focus though).

Factual errors

One Wakandan subtitle has a misspelled word: "descendant" appears as "descendent".

Continuity

The beard of Chadwick Boseman changes in length from take to take. At the beginning of the movie, at 7:58 it is long, then at 8:06 it is short, then at 8:11 is long again.

M'Baku says that he are his people are vegetarians, yet he claims that T'Challa was found by one of their fishermen.

After the heist at the Museum of Great Britain in London, the getaway vehicle is shown to be driving on the wrong side of the road as it speeds away.

Factual errors

Whem M'Baku challenges T'Challa he refers to the blessings of Hanuman, the monkey god. When the queen of King Ram (of India) was kidnapped a monkey was found in the forest with her scarf, indicating a route that pointed to the the King of Ceylon (Sri Lanka) as the kidnapper. By saving the queen the monkey was given the name Hanuman. Hanuman is not the name of an African monkey god, but of India.

Incorrectly regarded as goofs

When Erik Kilmonger finally dons the black panther suit, he is well clothed. When the sonic stabilizers deactivate his suit during the final fight, his bare skin is revealed and you can tell that he is not wearing a top. That's because his clothes were clearly disintegrated as the panther suit was forming.

Miscellaneous

There are various cultural aspects that are a bit off. For example, a queen (and certainly not a queen mother) would not dance in such a ceremony as it would be undignified, plus the use of an obscene gesture by the king's sister was also inappropriate even in humor. Africans are far more polite than Europeans, and Americans in particular.

Miscellaneous

The mixture of languages and occasional use of single words can be very odd. For example, when Zuri congratulates T'Challa, the latter responds with "mzuri" which is Kiswahili for "good."

Factual errors

The blankets are not worn properly. Rather, they are arranged like western shawls.
