VFX for 9/11

This page collects the visual-effects and animation work Terminal FX contributed to 9/11, Martin Guigui’s 2017 drama adapted from the stage. The premise — a handful of characters confined to a single elevator car — puts almost the entire effects load off-screen: what lies beyond the doors, beyond the windows and beyond the building has to be constructed, then handed back as something the actors appear to be reacting to. A breakdown separates those constructed layers from the photographed ones.

Restraint is the hardest brief in this kind of work. Effects attached to a real and heavily documented event cannot look designed; the reference is documentary footage, so simulated smoke and dust have to inherit its behaviour — plumes carried by wind rather than choreographed, debris that falls with weight, light that dulls as the air thickens. A cramped set demands exact tracking and patient rotoscoping through steel, mesh and moving bodies, while the composite carries the real burden: matching grain, flare, glass reflection and colour so that nothing added ever reads as newer than the plate. Set extension, atmospheric simulation, cleanup and invisible compositing are everyday Terminal FX work, and this page gathers that side of the film.
