Raymond Egerton Harry Watt (18 October 1906 – 2 April 1987) was a Scottish documentary and feature film director, who began his career working for John Grierson and Robert Flaherty.
In 1932, Watt joined the Empire Marketing Board Film Unit under John Grierson and began working on documentaries.
In 1936 Watt became a director for the London unit of the American newsreel series March of Time, where his films included England's Tithe War (1936).
Watt then joined the GPO Film Unit where he made his reputation as a documentarian with Night Mail (1936) which received much acclaim.
Watt went to East Africa on a similar mission to the one he had for The Overlanders – travel around the country, and find a subject for a film.
