Is Reflection in a Dead Diamond Worth Watching? Our Review

This Reflection in a Dead Diamond review starts with a warning: this is a spy film built from style first and plot second. Hélène Cattet and Bruno Forzani, the Belgian-French duo behind a run of stylised genre experiments, return with an 87-minute fever dream on the Riviera. If you like your thrillers dazzling and strange, read on.

Reflection in a Dead Diamond Review: The Story So Far (No Spoilers)

The Reflection in a Dead Diamond plot begins in a sun-bleached luxury hotel on the Côte d'Azur. John Diman, a charming ex-spy now in his seventies, spends his days in quiet elegance. Then the woman in the room next door vanishes.

Her disappearance pulls Diman toward figures from his old life. The film slides between the present and a lurid, pulpy version of his past, where espionage, cinema and unreliable memory overlap. It is less a straight mystery than a puzzle of images, and the film seems happy for you to feel a little lost.

The original French title is Reflet dans un diamant mort, and the film is a mix of action movie and mystery tropes filtered through 1960s and 70s Euro-spy pop culture.

What Works in Reflection in a Dead Diamond

The look is the main event. The directors pile on saturated colour, glittering surfaces, sharp edits and playful visual tricks, so almost every scene feels like a pop-art comic panel come to life. Even when the story is hard to follow, the frame is rarely dull.

The film also has a clever central idea. Treating an old spy's memory as a kind of movie, edited, exaggerated and glamorised, gives the genre homage some emotional weight. Aging, vanity and regret hover beneath the glossy surface.

• Bold, tactile style with a clear love of vintage spy cinema

• A short runtime that keeps the experiment from overstaying its welcome

• A mischievous tone that treats danger as theatre

Fans of the directors will find their signature approach to sound and editing in full force. If you want a broader sense of the genre, our mystery movie reviews offer plenty of alternatives.

Reflection in a Dead Diamond Cast and Performances

The Reflection in a Dead Diamond cast is anchored by two actors sharing one role. Fabio Testi plays the older John Diman with relaxed, silver-haired suavity, while Yannick Renier plays the younger Diman in the past sequences. Together they sell the idea of a man haunted by his own legend.

Koen De Bouw appears as Markus Strand, Maria de Medeiros as Laura, Thi-Mai Nguyen as Serpentik and Céline Camara as Amanda. The characters lean toward archetype, in keeping with comic-book spy fiction, so the performances are about presence and attitude more than psychological depth. That suits the material, though it keeps the emotional temperature cool.

Where Reflection in a Dead Diamond Stumbles

The same abstraction that makes the film distinctive can also hold viewers at arm's length. Story threads loosen and loop back, and the dreamlike logic may leave newcomers frustrated. If you want clear stakes and tidy answers, you may feel shut out.

The style also risks becoming relentless. Over 87 minutes, the barrage of visual flourishes can feel more like a showreel than a story that builds. Audience reaction has been mixed, with a TMDB score of 6.1/10 from 97 votes, which matches that split between admiration and fatigue.

Is Reflection in a Dead Diamond Worth Watching?

Yes, if you are curious about stylised, art-house genre filmmaking, though it is not for everyone. This is a film to admire for its craft and imagination rather than follow for its plot. Going in expecting a conventional spy thriller will likely disappoint.

As a short, strange, beautiful experiment, it earns a moderate recommendation. Read more about the film's background on Wikipedia before you decide, and browse our action movie reviews if you prefer something more direct.
