British Instructional Films was a British film production company which operated between 1919 and 1932. The company's name is often abbreviated to BIF.
The company released a number of feature films during the late silent film and early sound eras, developing a reputation for making short documentaries.[1] These included the Secrets of Nature series (1922-1933), consisting of 144 films. Filmmaker, historian and critic Paul Rotha described these in 1930 as "the sheet anchor of the British film industry".[2][3]
In 1928, the company constructed Welwyn Studios. The company was later merged into the larger British International Pictures, which took over the running of the facility in Welwyn Garden City.
