The Camels are Coming (film)

The Camels are Coming is a 1934 British comedy adventure film directed by Tim Whelan and starring Jack Hulbert, Anna Lee, Hartley Power and Harold Huth. A British officer in the Royal Egyptian Air Force combats drug smugglers.

Many of the scenes later had to be reshot in London as sand had got into the cameras, and high winds prevented the recording of dialogue.
