Several years after this film was made, the Woolner Brothers planned to do a bigger-budget sequel that would be shot in CinemaScope and color. A final script was written and printed, but the film never went into production.
Both of the film's leading ladies met with unfortunate ends. Allison Hayes died at the age of 46 due to lead poisoning from calcium pills she had been taking, while Yvette Vickers' mummified body was discovered in her home in 2011. Although she was 82, the evidence suggested that she had died of natural causes and the body lay undiscovered for over a year.
