In spite of the persistent rumor that special effects artist Russell Shearman was attacked and killed by a shark while filming underwater in the Caribbean Sea off Cuba, his May 8, 1956 obituary in the Los Angeles Times states that he and was "electrocuted while repairing equipment" for the film. He was taken to the nearest hospital but was dead on arrival. Serving as the picture's "chief technician", he was renowned for the "development of many machines and gadgets used in motion-picture production", said the Times, and was not an underwater cameraman or working as one when electrocuted.
After Lt. Cmdr. Staves' first trip out on the boat, a radio broadcast announces the capture of Munda on New Georgia in the Solomon Islands. That date would be August 6, 1943.
This film was adapted for Dell Comic's "Four Color" series, #762 in January 1957.
By the ribbon on his uniform, Lt. Cmdr. Staves was awarded the Navy Cross, the second-highest military decoration only to the Medal of Honor.
After one more feature, director Jerry Hopper would work primarily as a television director, a career that would last until 1987.
