During the 1930s, the studio was run by Julius Hagen. Hagen built up his business making Quota quickies for major American studios who were required by law to produce a certain number of British films each year to be allowed to release their pictures into the lucrative British market. Hagen became very efficient at producing large numbers of these quickies of varying quality. He often filmed all day, and then brought in different crews and actors to work through the night.
