For the film:
- Big-Lipped Alligator Moment: The blackface scene comes out of nowhere, was filmed probably ten years beforehand by an entirely different crew, and adds nothing to the plot. It is also the only comedy scene in a dramatic film.
- Reality Subtext: According to Fuller, Steve Reeves was a cold fish during their kiss scene, and didn't react. You don't say...
- What Could Have Been: The role of Dr. Boris Gregor was reportedly written for Bela Lugosi.
