During the shoot, troubles arose as no hotel reservations had been made for the crew. They were shifted from hotel to hotel, sometimes on a daily basis. Director Guillermin never was allowed to see the rushes. By order of the producers, footage was sent directly to them in London. A lighter moment occurred during a love scene between Chiles and MacCorkindale, when a hostile desert fly landed on Chiles's teeth. The actors carried on as best they could, but the crew burst out laughing when Guillermin thankfully called "cut" and ordered another take.
