One on Top of the Other

One on Top of the Other (Una sull'altra, 1969) is a Lucio Fulci mystery thriller you can watch online on iFILM. This early giallo from the future horror director plays out in San Francisco, where Dr. George Dumurrier runs a clinic with his brother, stays married to his asthmatic wife Susan, and keeps a secret affair going with photographer Jane.

Then Susan dies, and George's life starts caving in. A massive life-insurance payout surfaces in his favor, and the police read him instantly as a man who killed for money. Soon after, he crosses paths with a stripper named Monica who looks unnervingly like his dead wife. Is it her, a double, or a piece of an elaborate trap? The film keeps you suspended in that doubt right to the end.

Fulci is working in a Hitchcock-meets-French-noir register here, still years away from his gory horror reputation. Marisa Mell plays both women, and that dual role is the live wire running through the whole picture. Stylish, sensual and twisty, it's European thriller bait for fans of giallo and mistaken-identity plots. Stream One on Top of the Other (1969) online on iFILM.
