Factual error: When Ahmet is describing his idea for the song "The Mess Around" to Ray, he tells Ray the song is in G (major). However, Ray immediately plays the song in E flat major.

Factual error: In a scene where Ray and several others are riding in an automobile they pass underneath a railroad bridge. Passing over them on the bridge is a modern day container type train,a train of the era that the film portrays would be made up mainly of boxcars, tank cars, etc. not shipping containers.

Continuity: At the beginning, Ray holds out a ticket for the bus driver to see. In the next shot, from behind, both Ray's hands are at his side. When the shot changes back to the front, his right hand is extended again holding the ticket.

Visible crew/equipment: When Ray is in his new recording room, there's a shot of a white man near a TV, and the reflection of the camera is visible on the TV.
