"The SPN developed various actions to shape the thoughts and behaviour of the Portuguese society. One of the first initiatives that employed the film discourse was put into action on 14 December, 1936, as part of an anti-communist campaign directed mainly to the Portuguese proletariat. To this end, the Salazarist organism equipped a special lorry with all the equipment necessary to screen patriotic documentaries at the Casas do Povo (People’s Houses) of some towns, which were the primary unit of corporate rural organisation during this time.
The success of António Ferro’s initiative forced the government to reconsider very soon this idea of bringing the cinema of the SPN to the rural areas. Immediately, the government decided to create a more complex and effective traveling organism that could take its propaganda to the Portuguese provinces more quickly and often, without having to build cinemas around the country. In this way, the People’s Mobile Cinema, inaugurated on 20 February, 1935, in Lisbon’s Sindicato dos Caixeiros, became a powerful weapon of mind control (cf. Paulo, 1994)."
