Raoul Servais (Belgium, 1928) is considered a pioneer of animated film. His works enjoy world fame. He made sixteen short films and the feature film Taxandria (1994), a combination of live action and animation. His oeuvre was awarded over sixty prizes, including the Palme d'Or at Cannes for Harpya in 1979. He is the creator of Servaisgraphy, a technical process that combines live-action and animation relatively easily, successfully applied in Nocturnal Butterflies (1998), a nostalgic evocation of the world of painter Paul Delvaux.
