One on Top of the Other (Una sull’altra), directed by the legendary Lucio Fulci, stands as a quintessential example of the Italian giallo genre. Released in 1969, this psychological thriller combines intrigue, eroticism, and suspense, marking Fulci’s first foray into the mystery-thriller style he would later become renowned for.
The film stars Jean Sorel as Dr. George Dumurrier, a philandering doctor whose life spirals into chaos after the sudden death of his wife, Susan (Marisa Mell). When Susan’s death reveals a hefty life insurance policy payout, suspicions arise, particularly when George encounters Monica Weston, a nightclub performer who bears an uncanny resemblance to his late wife. As the plot unfolds, One on Top of the Other delves into a labyrinth of deceit, lust, and murder, keeping viewers guessing until the very end.
Fulci’s direction is a masterclass in atmospheric tension. The film blends vivid cinematography with stylistic flourishes characteristic of giallo, such as bold color palettes, meticulous framing, and intricate storytelling. Cinematographer Alejandro Ulloa captures the sensual allure of late 1960s San Francisco, where much of the film is set. The city’s fog-drenched streets and modernist interiors provide the perfect backdrop for this tale of duplicity.
A key highlight of the film is Marisa Mell’s dual role as Susan and Monica. Mell’s performance brings a magnetic duality to the narrative, portraying both characters with an enigmatic intensity that leaves audiences questioning their motives. Jean Sorel complements her with a portrayal of George that oscillates between guilt and desperation, adding to the film’s tension.
One on Top of the Other was groundbreaking for its provocative themes and visual daring, pushing boundaries with its exploration of sexuality and morality. Its mix of psychological complexity and suspense set the stage for Fulci’s later works in the giallo and horror genres, such as Don’t Torture a Duckling (1972) and The Beyond (1981).
While the film initially garnered controversy for its explicit content, it has since been reappraised as a standout entry in Fulci’s filmography and the giallo canon. Today, One on Top of the Other continues to intrigue fans of psychological thrillers, offering a stylish and compelling mystery that showcases Lucio Fulci’s visionary storytelling.
