The MPC Paris teams handled the supervision, digital visual effects production, and picture post-production for Stéphane Demoustier’s new film, The Great Arch (L’Inconnu de la Grande Arche).

Under the supervision of VFX Supervisor Lise Fischer, working alongside VFX Producer Loriane Lucas and Compositing Supervisor Philippe Desfretier, MPC Paris assembled a team of 30 artists over four months to create and integrate more than 100 visual effects shots. One of the major challenges was precisely recreating the construction site at different stages of its development.

To remain faithful to historical reality while respecting the filmmaker’s vision and production constraints, the decision was made to use archival footage as the primary material for all wide shots establishing key sequences. The team combined advanced digital techniques — CGI environments, matte painting and compositing — with meticulous documentary research based on historical archives.
