Chronovisor is one of my favorite films that I’ve seen all year, and also one that I will find myself reluctant to recommend to others. Similar to 2024’s Last Things, it is a kind of science fiction documentary, and although I was thoroughly enraptured by it, I must also acknowledge that it is a film in a challenging, novel format, and it will likely be a difficult sell for most audiences. The question of whether one will find it fascinating or banal will largely come down to how much you enjoy doing research. This is a roughly 100-minute feature in which the first eighty minutes involve watching someone else performing academic research and cross-referencing various texts and recordings before the final twenty minutes turn into a psychedelic sequence that is both dream and nightmare. If you have the patience for it, it’s quite an experience, but I also don’t expect that many viewers in the audience will be willing to go along for the entire ride.
Dr. Béatrice Courte (Anne Laure Sellier) is a professor at Columbia University whom we meet boring her colleagues over dinner with a long monologue about oratory rhetoric and mind palace techniques. It functions as a litmus test for the rest of the film. If you’re as disinterested as her dinner companions are, you’re not going to enjoy the rest of the movie, but if her extemporaneous lecture about historical memory techniques intrigues you, you’re going to be completely engaged. She returns home to her lonely apartment and resumes her ongoing research, which largely revolves around a parascientific device, the titular “chronovisor.” Allegedly invented by a group of scientists and clergyman, foremost among them a Benedictine monk named Pellegrino Ernetti, the chronovisor was a device that, by interpreting the “echoes” of events, allowed the user to view and even photograph history, including the day of Jesus of Nazareth’s crucifixion. Through reviewing videotapes of lectures, reading through dozens of historical texts in multiple languages (which are translated for us in the audience as textual overlays on the page), listening to cassettes of talks given by various pseudoscientific figureheads, and playing vinyl records of Gregorian chants collected by Ernetti, Beatrice uncovers a historical mystery, one with potentially unfathomable effects on our understanding of history, faith, and reality. Was the chronovisor real? What happened to it?
The camera’s eye alternates between providing an omniscient view of Béatrice as she goes about her research in various sumptuous, antiquated libraries (the press materials mention the German Society of Philadelphia, the NYC Yale Club, and the George Peabody Library at Johns Hopkins) and allowing us to see the documents and magazines that she peruses from her first-person point of view. This is the place where the film will either succeed or fail to engage the audience, as it effectively captures the feeling of doing research, which is something that I find delightful while understanding that my reaction represents a fairly small minority. Other than a couple of dinners that she attends with her fellow scholars that establish that she is isolated even within the academic world and a single scene in which she requests a long list of material from an unseen librarian, we don’t see her interact with others until she’s fully devoted to the pursuit of the truth about the chronovisor, as she concocts various narratives to spin over the phone with publishers, biographers, and distant relatives of Father Ernetti and his cohort. All the while, the text on screen that lays out the events of his life and research vacillates between factual translations of texts and hyper-edited remixes of the words therein into montages that read like flash poetry.
It’s compelling stuff, if the prospect of doing research into a paranormal device is exciting to you. As such, I would expect this film to land best with a viewer who enjoys variations on mystery narratives and who is already in tune with this kind of “ride along with the investigator” narrative, by which I mean that this is likely to find an audience among (patient) people with an interest in true crime. That may seem ironic, given that I myself am not a proponent of that genre generally, but it’s ultimately rather fitting, given that the chronovisor is real, or at least, it was a real hoax. Pellegrino Ernetti was a real Italian monk, one who really did generate and distribute a wealth of scholarship about Gregorian chants and other early ecclesiastic music, and he really did announce the invention of the chronovisor in the May 1972 issue of Domenica del Corriere (Italian for Sunday Courier). That article, “A Machine Has Been Invented That Photographs the Past,” was the catalyst for writing/directing/editing duo Jack Auen and Kevin Walker to dig into Father Ernetti’s claims, just as we witness Béatrice doing. Although the “evidence” provided for the chronovisor’s functionality was ultimately refuted; a widely distributed, supposed photo of Christ was found to be identical to a souvenir postcard of a Lorenzo Coullaut Valera sculpture in a remote Spanish church, and the alleged recreation of the lost Latin tragedy Thyestes was dismissed by a contemporary academic as betraying that its author had only a rudimentary understanding of the language. Chronovisor takes this real-life counter-evidence as proof of deliberate suppression, and builds a mystery around it.
Of course, you probably surmised from the breakdown in the opening paragraph above, Béatrice does eventually track down the location of the device. By this point in the narrative, we have learned that users of the device not only observed the events of the past but became psychically entangled with them, so we know that Béatrice’s discovery does not bode well for her. We once again bear witness to what she sees through her own perspective, as she engages with the machine and perceives history through a distorted lens that brings the “etch-a-sketch” visuals of the 1984 erotic thriller Blind Date to mind. This is the part of the film that I would expect to alienate the true crime audience, as it will speak more to fans of experimental filmmaking, and once you’ve met enough members of both those groups, you’ll understand that the overlap in the Venn diagram between them is small. That’s a great misfortune, as this is a very rewarding journey for those patient enough to allow the mystery to be doled out to them in this novel and inventive form.
As a visual effort, Chronovisor is gorgeous. It’s shot on 16mm, which gives a lot of text and depth to what we see on the screen, which is wise when many of the shots are almost indistinguishable from a still photo. Béatrice is portrayed not by a trained actor but by an actual academic. Sellier is a faculty member at the London Business School, NYU’s Stern Business School, the Columbia Business School, and a Cartier-Chaired Professor at the Paris School of Advanced Business Studies. That may not seem to be terribly aligned with Béatrice’s area of expertise, but she is currently researching creativity, cognitive biases, and human perception of time, and she carries that academic authority into the role, such as it is. Béatrice is, ultimately, little more than a cypher who decodes the mystery of the chronovisor for the audience to experience vicariously. What little we might surmise about her as a character other than her dedication to study is all interpretive (she wears a wedding ring despite no mention or appearance of a spouse, from which we can speculate a motivation on her part to see a deceased partner, but nothing more). This is not to the film’s detriment, however, any more than its insistence upon the use of antiquated technology is. If one were to forget or overlook the presence of recent car models on the street or a letter being dated (via typewriter!) February 2026, then the film feels like a period piece until the moment that Béatrice picks up her smartphone to start making calls. It makes for a bit of playfulness, which is welcome in a film that most people will complain feels like a group study project.
If I’ve managed to sell you on Chronovisor, the distributor’s website currently includes a “where to watch” drop-down at the bottom of the page so that you can check for screening dates near you.
