The Mill provided visual-effects supervision and delivered 60 VFX shots for The Golden Age (L’Âge d’or), a feature film directed by Bérenger Thouin and produced by GoGoGo Films. The work integrated contemporary actors into archival footage from Gaumont Pathé Archives, creating interactions between new performances and historical imagery. The film was shot in black and white and then fully colorized to harmonize newly filmed material with restored archive sequences.
