3. Black Gold

Co-directed by Nick and Marc Francis, this documentary is an eye-opening expose of the multi-billion dollar coffee industry and one man's fight for a fair price. Told through the eyes of Tadesse Meskela, manager of a co-operative union that represents 74,000 Ethiopian coffee farmers, the film highlights the complexities of an industry worth over $80 billion - the world's second most valuable trading commodity after oil.
