MPC - The Great Arch VFX Breakdown

The Great Arch directed by Stéphane Demoustier [L'Inconnu de la Grande Arche] (2025)

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

Under the supervision of VFX Supervisor Lise Fischer, working alongside VFX Producer Loriane Lucas, 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.

SYNOPSIS
1983. French President François Mitterrand decides to launch an international architectural competition for the flagship project of his mandate: the Great Arch of La Défense, aligned with the Louvre and the Arc de Triomphe. Against all odds, Otto von Spreckelsen, a Danish architect, wins the competition.

Overnight, this 53-year-old man, unknown in France, arrives in Paris where he is propelled at the helm of this pharaonic project. While the architect intends to build the Great Arch exactly as he envisioned, his ideas quickly clash with realistic constraints and the vicissitudes of politics.
