Filmed in August 1953, but not released until February 1954. Rumored to have been filmed in 3-D but only released in 2-D.
This was the first film credit for Roger Corman, listed as co-producer and co-author of the story. Corman, of course, went on to produce and/or direct hundreds more films for the next 68 years (and counting).
The name of the waitress at the cafe is listed as 'Dolly' but the trooper repeatedly calls her 'Sally'.
The car Jim, Mrs. Cummings and Susan drive in the desert is a 1953 Dodge Coronet Sierra station wagon.
Jim complains that he spent 65 cents on the Las Vegas strip buying the murdered woman a martini. Adjusted for inflation, that would be $7.41 in 2024. However, prices were comparably cheaper in the good old days. A martini on the Las Vegas strip in 2024 costs $15-$25.
