Dario Argento's 1987 horror film 'Opera' (also known as 'Terror at the Opera') stands as one of the Italian maestro's most visually stunning and psychologically intense works. The film follows Betty, a young understudy thrust into the lead role of Verdi's 'Macbeth' at a prestigious opera house, only to become the target of a mysterious, sadistic killer. The psychopath's signature method involves taping needles beneath Betty's eyes to force her to watch as he brutally murders those close to her, creating a terrifying game of observation and survival.

The film showcases Argento at the height of his technical prowess, featuring elaborate crane shots, inventive camera work, and the director's trademark operatic violence. Cristina Marsillach delivers a compelling performance as the traumatized Betty, effectively conveying vulnerability and resilience. The supporting cast, including Ian Charleson and Urbano Barberini, adds depth to the mysterious narrative that cleverly intertwines the superstitions of 'Macbeth' with the killer's motives.

'Opera' is essential viewing for horror enthusiasts and cinephiles alike. Argento masterfully blends giallo mystery with grand operatic atmosphere, creating a sensory experience that is both beautiful and brutal. The film's exploration of forced witnessing and trauma remains psychologically potent, while its set pieces—particularly the murder sequences—are executed with breathtaking precision. With its haunting score by Brian Eno and Claudio Simonetti, and a finale set against a stunning Swiss landscape, 'Opera' represents a high-water mark in European horror cinema that continues to influence filmmakers today.
