JOHANNESBURG — Documentary filmmakers will get help securing international co-production deals in a joint initiative by the Sithengi Southern African Intl. Film & Television Market and Encounters, the South African Intl. Documentary Festival.Encounters and Sithengi have designed a program leading up to the docu co-production forum during Sithengi 2003, to be held Nov. 13-16 in Cape Town, aimed at helping filmmakers develop and prepare their pitches more effectively. This will ensure projects are backed by a South African broadcaster before they are pitched to international producers for co-prod deals at Sithengi. Filmmakers have been invited to submit docu proposals to a selection panel during Encounters in Cape Town from July 20-29 and in Johannesburg Aug. 1-7.
