World War Z: 3D Converted by Prime Focus

Prime Focus World delivered View-D stereo 3D conversion services for Brad Pitt’s apocalyptic horror movie World War Z. The film opens in the US and UK on 21 July 2013.

The Story

Directed by Marc Forster (Monster’s Ball, The Kite Runner, Quantum of Solace) for Paramount Pictures, and based on the novel of the same name by Max Brooks, World War Z sees United Nations employee Gerry Lane (Pitt) travelling the world to stop a deadly zombie pandemic that is defeating armies and bringing down governments.

Conversion Work

Prime Focus delivered 2076 converted shots for WWZ, with nearly 400 artists working on the film in London and Mumbai. They modeled Brad Pitt’s face and created a depth matte from this geometry that the artists could use to ensure consistency and accuracy in the depth sculpting of his features. The artists match moved the model of Brad's head to each shot to generate an accurate Zdepth. On faster moving and mid/wide shots, the geo head was used side-by-side in the View-D comp for reference when sculpting.

The 3D edit was dione at PFW in London, building a dedicated editorial team to maintain the stereoscopic 3D reels and mirror the live 2D cut. This allowed PFW to become the stereo hub for the movie, facilitating daily 3D reviews with the filmmakers – not just for our converted shots, but also for the 3D stereoscopic shots that Cinesite was contributing.

Prime Focus ran reviews from London with the filmmakers in LA, using PF's live dual stream 3D review system. This technology allowed the studio to stream 3D sequences directly from London to the LA review theater, and hold real-time reviews with the filmmakers.

The View-D FX team added particles and FX to really sell the 3D moments. From shattering glass flying out of the screen, to rain in theater space and dust particles floating out over the heads of the audience, the team really took advantage of the extra depth to create some truly outstanding moments in the stereoscopic 3D space.

When designing the depth for the zombies themselves, for once Prime Focus were not too worried about ensuring that the depth was completely accurate. Using depth as a creative tool, the team stretched and distorted the zombies to make them even more frightening, lifting their heads away from their shoulders as they swarm towards the screen and bringing them out up to 100 pixels into negative space! Wow effect guaranteed!
