Continuity mistake: Towards the end of the film: Killmonger is about to kill Shuri at the top of the mine shaft and Shuri is backing up. Her elbow goes over the edge, but in the next shot which is from over Killmonger's shoulder looking down at her, she is at least a foot away from the edge.
Factual error: The ambulance in the museum robbery scene has the registration number LD59 QQI. In the UK Q is never used within a registration number, only as a prefix for particular vehicles, for example kit cars. The letter I is also never used in any part of a registration number as it can be confused with a 1. (00:19:07)
