When Black Dynamite is shot in the shoulder and goes to the hospital, the doctor clearly says, "No fragments, in and out - you're very lucky, BD," indicating that the bullet went right through Black Dynamite. However he is only bandaged at the entry point of the bullet and there is no exit wound on his back.

The "ribbed" look of Dynamite's car top.
The boom microphone is visible several times on the top of the frame. Yet in the case of this movie, the mic being visible is a joke meant to parody the lack of film production expertise on the sets of the original "blaxploitation" movies that this movie is referencing.
In the diner scene, on the blackboard with the day's specials, scrambled is misspelled as "scrambed" and specials is written as "special's".
