There are so many reasons Black Orpheus is important to cinema. First, how many people know that prior to Marcel Camus making this film the late Orson Welles attempted to capture Rio Carnival but with no story, plot, or script? In 1942, Welles discovered voodoo was at the root of the carnival samba, and started filming in the favelas, the slum shanty towns on the hills of Rio...it was considered by Hollywood to be anti-establishment and dangerous by Brazilian authorities. Thus, Welles was not able to complete his film.
Samba is a Portuguese form of music, the word was derived from the West African bantu word "semba", meaning "invoke the spirit of the ancestors". Long outlawed as a dangerous expression of black slave culture, samba music eventually gained legitimacy and became a big part of carnival.
Nearly 20 years later Black Orpheus achieves what Welles was trying for and goes beyond it. To start Marcel Camus had a script to work from whereas Welles was trying to wing it on the spot. Camus successfully recreated the Orpheus-Eurydice myth using the Rio Carnival as the back drop. The main characters retain the mythological names, including the symbolic Death. This works because it is Afro-Latin culture where pagan-Christian names were more evident and because the Carnival itself was such an important part of the story. History manifests as a deja vu, a cyclical progression of event and re-incarnation, understood only by the occultic transformation of samba, trance and possession, for which the Carnival is the engine.
To those who misunderstand or are ignorant of samba, voodoo, or the Rio Carnival Black Orpheus may seem overwhelming, especially because of all the singing and dancing but samba (and Carnival) is ritual, in its most elementary form it is a raw cacophony of primitive drumming, clapping, chanting... and the droning cries of the dancers who stagger on the edge of the "stage", seeking possession and reincarnation.
Black Orpheus won the Palm d'Or in 1959 at Cannes. It was seen as progressive because it featured black actors and the pluralist culture of modern Brazil. It also gives outsiders a view inside of a ritualistic, non-Western culture and that is why it was and is so important to cinema.
