The first movie to be broadcast on television in 3-D.

Film debut of Patrick O'Neal.

The time setting of the movie is a bit vague, but it's clearly the time of gaslight and a time when fingerprinting to identify criminals was considered new and experimental. Francis Galton published a book, "Finger Prints", in 1892, laying the basis for identifying fingerprints and making them acceptable court evidence. Additionally, Frank Prentiss discusses "that Fall River thing" when talking about murder with his wife, Alice. This almost certainly refers to the Lizzie Andrew Borden case, which happened in 1892-1893. Also the soundtrack includes "Ta-ra-ra-boom-de-ay", which became popular in 1892.

Offered to theaters in both 3-D and a standard 1.85:1 format.

Veteran character actor Jay Novello came from Italian parents and usually played Latin types - Italian, Mexican, Spanish or South American - but here, most untypically, affects what is almost an English accent as Mr. Prentiss.
