Pedro Costa's Horse Money extends his collaboration with the Capo Verdean immigrants of Fontainhas in a new, surprising direction. The certainties of his earlier films have been stripped away, and what emerges is an incantation, a prayer, a mass, a film of memories we can only partly grasp, a documentary of dreams, a documentary as dream, a ghost story some would say, but certainly a film of astonishing power whose protagonists are the true heroes of our times.
