Il dio serpente (The snake god) is a 1970 Italian erotic fantasy film directed by Piero Vivarelli and featuring Italian-based American actress Nadia Cassini in her first lead role. The film is an earlier example of voodoo (and later zombie) themed sexploitation films shot in Colombia by Italian directors. The theme song of the film, "Djamballà" by Augusto Martelli, reached the first position in the Italian hit parade.
