Many accidents and delays occurred during filming in Africa. Many of the crew, including the director W.S. Van Dyke, contracted
malaria. An African crewman fell into a river and was eaten by a
crocodile. Another was killed by a charging
rhinoceros. The rhinoceros was captured on film and the scene was used in the final print. Swarms of many insects, including
locusts and
the-tse flies, were common and cast and crew was perpetually bitten or stung.
Female lead
Edwina Booth became infected, probably with
malaria or
schistosomiasis during filming. It took six years for her to fully recover from this and other conditions she endured. She retired from acting soon after and sued Metro-Goldwyn-Mayer. The case was settled out of court. A sound crew, sent halfway through filming, were unable to produce good quality work. This resulted in most of the dialogue sequences being reshot at the MGM studios in
Culver City, California. This caused rumours that the entire production had been filmed there, so most of this footage was cut from the final release. Many animal scenes were filmed in
Tecate,
Mexico, by a second unit to avoid the American laws on the ethical treatment of animals. For example, lions were reportedly starved to promote vicious attacks on hyenas, monkeys and deer.
