Drawing inspiration from the source material by Solange Fasquelle, “The Infernal Trio” marks the directorial debut of Francis Girod. Girod, like any aspiring filmmaker, undoubtedly aimed to make a lasting impression with his inaugural work, and this dark and chilling portrayal of body disposal certainly succeeded in leaving its mark, albeit for reasons that may unsettle some viewers.

The film centers on the notorious case of Georges-Alexandre Sarret, whose gruesome methods of disposing of his victims’ remains drew comparisons to infamous criminals like John George Haigh, the ‘acid bath murderer’. Sarret’s story culminated in a date with Madame la Guillotine in 1934, while his Bavarian accomplices, the Schmidt sisters, faced their own justice with lengthy prison sentences.

Portrayed by the talented Michel Piccoli and Romy Schneider, alongside Mascha Gonska as Catherine Schmidt, the film delves into the twisted dynamics of this utterly depraved trio. It’s the compelling performances and charisma of these three actors that elevate the film, making it bearable even during its most gruesome moments, such as the harrowing ‘acid bath’ sequence.

Particularly noteworthy is Schneider’s portrayal of Philomena Schmidt, a role that challenged her previous screen persona and showcased her versatility as an actress. In her mid-thirties at the time of filming, Schneider delivers a powerhouse performance, fully embodying the complexities of her character’s dark desires and actions.

While the film takes creative liberties for dramatic effect, omitting certain events like Sarret’s trial and execution, it remains a haunting and thought-provoking exploration of human depravity and moral decay. The decision to end the film with Sarret’s marriage to Philomena adds a chilling final note, leaving audiences to ponder the true depths of evil that lurk within the human soul.

In the end, The Infernal Trio stands as a testament to the courage of its cast and crew, who fearlessly tackled taboo subject matter with unflinching honesty and artistic integrity. As the film celebrates its 50th anniversary, it serves as a reminder of the power of cinema to confront the darkest aspects of humanity and challenge our perceptions of good and evil.
