The shoot was difficult. Gardner fell ill with dysentery during the shoot, requiring her to be flown to England (she recovered and flew back). There was a rumor Clark Gable was going to be assassinated by the Mau Mau, so John Ford moved a location. Two of the crew were revealed to be Mau Mau. The unit was plagued by rain and the poor quality of the roads - three of the crew were killed in road accidents, including assistant director John Hancock.
