Chicago Reader review:
Aptly titled—a lush, melodramatic portrait of seduction and betrayal, decadence and deceit in the midst of Italy's resistance to Austrian occupation in the mid-19th century, revealing Luchino Visconti at his most baroque and the Italian cinema at its most spectacular (1954). A fine tragic performance by Alida Valli and surprisingly good work by Farley Granger (imported for American box-office appeal) help overcome some of the obvious narrative gaps created by the Italian censors. Visconti's sinuous Marxism here begins to creep to the fore.
Here (and above) is the trailer.
