I Cover the War! (1937)

Bob Adams, ace newsreel cameraman, is told by his boss, "Get the picture---we can't screen alibis." He heads for Samari, a desert hot-bed of tribal unrest in Africa, to do just that, which includes getting footage of El Kadar, bandit and rebel leader. He gets his pictures but only after a romance with the Colonel's daughter Pamela, saving his wimpy, hacked-off brother Don from being a dupe of the gun-runners, and run-ins with spies and throat-cutting tribesman. For a finale, he saves the British Army.
