Watch full movie online. OPERA MORTEM is a medium-length film with strong surrealist/dadaist influences where distorted and disturbing images are shown without a real narrative thread which could be a visual dream of death that intersects the story of a suicidal girl and a necrophiliac killer. According to some theological scholars, the film hides a metaphorical evocative code of a satanic ritual. But perhaps David Fleas only followed the manifesto of the Dadaist movement, between anarchist, nihilistic and sarcastic ideas, giving voice to the search for that absolute freedom that art demands.
