Vegan Society film (about 30 min) produced for the BBC "Open Door" series in 1976.
Side note: "The society [Vegan Society] received a magnificent boost in publicity and resources in 1976 when covered by the BBC Open Door program. The [Vegan Society's] office received 300 phone calls, 9,000 letters, and a spike of several hundred new members. Its revenue multiplied several times. This growth allowed it to hire staff and rent a premise, but it also forced some complicating managerial decisions. In 1979, The Vegan Society (1979) changed to a Company Limited by Guarantee to relieve trustees of their growing duties. Some expressed concern that this bureaucratization would undermine the society’s founding spirit. Thus, as the society launched as a registered charity in 1980, 'Grassroots News' became a new section with emphasis on keeping a community and nurturing networking and local connection. The decision to bureaucratize could not have come sooner; the airing of The Animals' Film on UK’s Channel 4 just a year later had a mobilizing effect similar to that of Open Door." (Wrenn 2019)
