Production was delayed several days while the crew waited for cloudy daytime weather to add atmosphere to the big finale. This was just fine with star Ann-Margret. She had been introduced for the second time to future-husband Roger Smith, who was performing in a Frisco nightclub, and she wasn't looking forward to leaving him.
The voice of Zekial Marko is dubbed by Paul Frees.
