Firstly, in order to be able to shoot in any city of Brazil, one needs to be associated with a local producer and registered with Ancine (National Film Agency) (with the exception of journalistic productions).
The local producer will respond to Ancine on behalf of the foreign producer. In addition to acting as a communication channel with Ancine, the Brazilian company is responsible for compliance with local legislation and assistance in customs clearance, hiring of local crew, rental of handling equipment, and obtaining permits. Please first check the conditions on the Ancine website: www.ancine.gov.br/manuais/filmar-brasil/filming-brazil
