Un uomo in ginocchio (1979)

A regular working-class guy finds that a hitman has been hired to kill him.

From memory: Despite a rather complex plot, this is a straightforward and bleak gangster tale without any romanticism or heroism.

Inferno (1980)

An American college student in Rome and his sister in New York investigate a series of killings in both locations where their resident addresses are the domain of two covens of witches.

From memory: The plot is barely comprehensible, but seen as an intense, horrifying and mesmerizing dream, made with a keen eye for style, it is a quite fascinating work of art.

Halliwell (no star): "Absurdly overplotted and mainly incomprehensible shocker with some small pretensions to style."

Maltin**1/2: "Surreal, hypnotic shocker...is short on sense, but long on style."
