L'Âge d'Or - Inside the VFX

How do you make a fictional character feel as though she has always existed in historical footage?

For The Golden Age 'L’Âge d’Or', directed by Bérenger Thouin, The Mill faced a fascinating creative and technical challenge: seamlessly integrating contemporary performances into authentic twentieth-century archival footage, transforming historical images into a living cinematic world.

Selected for Cannes Classics, the film follows Jeanne Lavaur, played by Souheila Yacoub, through the upheavals of the twentieth century. Rather than recreating the past through conventional period sets and digital environments, the filmmakers chose to build their fictional narrative directly within real historical archives.

The Mill supervised and delivered 60 VFX shots, developing a highly hybrid approach that combined traditional visual effects techniques with emerging technologies.

A different approach for every archive

With around thirty archival sequences integrated into the film, no single technique could provide a universal solution.

Some shots relied on carefully crafted traditional compositing workflows, allowing Souheila Yacoub's performances to be integrated into historical footage. Others required more sophisticated techniques, including refined 2D face replacement and deep learning technologies to reconstruct facial performances and create convincing interactions with people captured decades earlier.

Each sequence presented its own challenges: inconsistent image quality, film grain, unpredictable movement, small facial details and the particular characteristics of each archival source.

Rather than applying a standardised workflow, the artists at The Mill selected and combined techniques according to the specific requirements of every shot. Deep learning opened up new creative possibilities, while traditional VFX artistry remained essential to refining, repairing and completing the images.

The result is a deliberately varied visual language, designed to preserve the authenticity of the original footage while making the fictional performances feel entirely at home within it.

Performance, precision and craftsmanship

The work began long before post-production. Close collaboration between director Bérenger Thouin, cinematographer Martin Roux and VFX Supervisor Hugues Namur helped define the visual approach from the earliest stages of the project.

To support the complex integration work, Souheila Yacoub took part in dedicated reference shoots, meticulously recreating gestures, movements, positions and timings observed in the original archival footage.

These performances provided invaluable reference material for both compositing and deep learning workflows, helping the artists reproduce the physicality and nuances of the historical subjects.

The production also combined digital techniques with practical on-set solutions, carefully matching camera angles, perspectives and lighting conditions to the original footage. Sometimes, the simplest practical adjustment made the biggest difference to the final image.

Technology guided by artistic vision

The Golden Age demonstrates how visual effects can become an integral part of the filmmaking process, rather than simply a finishing stage.

By combining traditional compositing, face replacement, deep learning and hands-on digital craftsmanship, The Mill helped create a visual experience in which the boundaries between archive and fiction gradually disappear.

The ambition was never simply to make the effects invisible. It was to make the historical footage feel alive, allowing audiences to experience these images as part of the film's narrative.
