Assistant director Tony Kelly disappeared whilst shooting second-unit footage along the Zambesi River in Rhodesia. When the crew's boat overturned, the other two crewmen were able to swim to safety, but Kelly, although the strongest swimmer of them all, disappeared in the water. It is thought he was trying to save the camera equipment and many theories were offered for the disappearance, the most fearful being that he had been taken by crocodiles. No body was ever found.
The same year, Dana Andrews starred in "Elephant Walk". In both movies, he romances or tries to romance an American woman either married to or engaged to a wealthy, powerful Englishman.
Online, this movie was available for download under the title "The Search for a Millionaire".
One of several British b-movies starring Dana Andrews in the 1950's, the other being the most famous, "Curse of the Demon".
Dana Andrews says to Jeanne Crain, "Destiny seems to insist on throwing us together." They had in fact worked together in State Fair (1945) the previous decade; and two more times after: Madison Avenue (1961) and Hot Rods to Hell (1967). In State Fair and this movie, they meet, and have a romance at the very end. In Madison Avenue they had been dating sporadically, and basically use each other. And Hot Rods to Hell is the only picture in which they play a married couple.
