The opening scene which features an African-American actor using an effected quasi-English accent and precise diction while delivering his lines is a play on several well known actors who are featured in blaxploitation yet got their roots in William Shakespeare performances. William Marshall, star of Blacula (1972), starred in eight different productions of Othello before playing Mamuwalde/Blacula in 1972.
The boom microphone is visible several times on the top of the frame. Usually if a boom mike is visible in a finished film, it is either because of a mistake made by the filmmakers during shooting or (much more frequently) a mistake made by the projectionist at the movie theater - but in the case of this movie, the mike 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.
Michael Jai White has stated he was not just playing Black Dynamite, but also the actor playing Black Dynamte. The actor, Ferrante Jones, was a running back for the Baltimore Colts whose career ended due to a broken neck. If you pay attention you'll notice that Black Dynamite has a hard time turning his neck to one side. This is because of Jones' neck injury.
Michael Jai White first had the idea for the movie while filming Undisputed 2: Last Man Standing (2006) in Bulgaria. James Brown's Superbad was playing on his iPod and the "blaxpoitation" film idea came to him. He first wanted to call the film Superbad (2007), but that title had already been taken so he came up with "Black Dynamite".
The sex scene that introduces us to Black Dynamite at the beginning of the film features visual references to two Dolemite films starring Rudy Ray Moore. The alternating of POV and over the shoulder shots are the same techniques used for sex scenes in both Dolemite (1975) and The Human Tornado (1976).
