Lux Æterna

The film takes place on a contemporary film set, primarily in a dressing room and on a shooting stage. The production environment functions as both a working studio with lights, cameras, and crew, and as a metaphorical pressure cooker where the politics of cinema play out.

The story is set in the present-day modern filmmaking world. However, a 1920s-styled documentary montage is intercut throughout, creating a contrast that suggests past cinema continues to haunt contemporary filmmaking practices.

The film interrogates the director's demand for absolute control, using on-screen quotes from Buñuel, Dreyer, and Fassbinder to frame its inquiry. The clashes between producers, the cinematographer, and actors reveal how power dynamics shape what ultimately appears on screen, examining artistic authority versus collaborative creation.

Characters grapple with persona and performance as both Charlotte Gainsbourg and Béatrice Dalle play heightened versions of themselves. The split-screen structure and behind-the-scenes footage blur the lines between their real selves and screen identities, probing how fame reshapes agency and what remains authentic when cinema becomes the subject matter itself.

The infamous witch-burning sequence becomes a meta-spectacle that exposes the artifice and peril of cinematic truth. Technical glitches including rear projection failures and loud drone sounds turn the production into disruptive performance art, testing actors' endurance and questioning what price both performers and audiences pay for dramatic intensity.

Charlotte Gainsbourg plays a version of herself, an acclaimed actress navigating the chaotic on-set atmosphere. She questions how women are represented in cinematic storytelling while enduring the director's demands and crew tensions. Her performance serves as a through-line anchoring the meta-narrative about art, power, and collaboration.

Béatrice Dalle plays a version of herself, an iconic actress who pushes to keep the shoot moving despite delays and pressure. She actively challenges the cinematographer and producers, defending bold choices while clashing with the crew. Her passion and stubbornness illuminate the film's inquiry into authority and collaboration on set.

Quotations from these iconic directors appear on screen to frame conversations about directorial will and vision. The film uses these references to critique film industry norms around depiction, censorship, and the portrayal of women. The on-set discussions reveal how cinematic theory and practice collide in real-time, making language itself a tool of authority.

The 1920s-styled documentary montage contrasts sharply with the contemporary on-set chaos, creating a visual and temporal disruption. This stylistic choice hints at how the ghosts of past cinema continue to influence and haunt modern filmmaking practices, reinforcing the film's exploration of memory and time in the creative process.

The characters are making a film about witches, specifically one that examines how witches and women are depicted in cinema. The on-set debates about representation and the portrayal of women become central to the movie's meta-inquiry into the film industry's treatment of female subjects and performers.

The film functions as a critique of the film industry by exposing the power struggles, gendered dynamics, and artistic compromises that occur on set. Through its tense, close-quarters dialogue and meta-narrative structure, it examines how directors chase absolute authority while actors and crew navigate exploitation and psychological distress.
