Argon FX

Argon FX is an independent, London-based studio specializing in previsualization, postvisualization and visual story development for feature films and high-end television. Its work helps directors, visual effects supervisors and editors develop complex sequences from early ideas and storyboards through production and post-production.

The studio explores how a sequence will play before filming begins. This includes camera staging, virtual camera layout, lens choices, action timing and the integration of locations into a scene. By turning developing ideas into shots, its artists help filmmakers assess pacing, visual continuity and practical production decisions before committing to live-action photography.

From sequence design to editorial

Previs provides a working version of a sequence in which filmmakers can test camera angles, choreography and staging. The studio's remit includes complicated action and large-scale combat, where the relationship between cameras, performers and digital elements needs to be resolved before shooting.

During post-production, Argon FX creates temporary digital elements and animatics for working edits. This postvis work allows directors and editors to continue shaping sequences while maintaining coherence between live-action footage and planned effects. These interim shots support editorial decisions before final visual effects are completed by external vendors.

Its production work includes battle sequence development for Napoleon, previsualization for The Martian, and the rotating cable-car sequence in Kingsman: The Golden Circle. Other assignments include previs and virtual reality concert layout for Bohemian Rhapsody, alongside work on Murder on the Orient Express, Cinderella and Dark Shadows.

Company background

The business's legal history began with incorporation as McDonald Animation Limited in 2005. It subsequently operated as Polar Films Limited before adopting the Argon Effects name in June 2011, the milestone reflected in its tagline, “Resolving sequences since 2011.” Its practice centers on visual problem-solving across the filmmaking process, connecting early sequence development with the evolving needs of production and editorial.
