From face replacements to shattering soldiers, from CG trolls to magic metallic mirrors, Snow White and the Huntsman uses an incredible and diverse range of visual effects to re-tell the classic fairytale. fxguide has interviews with all the lead vendors – Double Negative, Rhythm & Hues, Pixomondo, Lola, The Mill, Hydraulx, Baseblack, BlueBolt and Nvizage, plus overall visual effects supervisor Cedric Nicolas-Troyan.
Working together with co-visual effects supervisor Phil Brennan, Nicolas-Troyan co-ordinated a wide range of shot-types – 1300 in all – for director Rupert Sanders’ first feature film. “I think besides spaceships and exploding New York, we’ve done everything that’s in the visual effects book!,” he jokes. “We’ve done creatures, transformations, animals and plants, buildings, fire and so much stuff. Cloth simulations, liquid metal, dynamics, face replacements. You name it – it’s somewhere in the movie.”
The film tells the story of Queen Raveena’s (Charlize Theron) dark rule after she has imprisoned Snow White (Kristen Stewart), until White teams up with The Huntsman (Chris Hemsworth). Some of the overriding principles for the visual effects work were the ideas of the Queen being ‘death’ and Snow White being ‘life’. “For example,” says Nicolas-Troyan, “we wanted these dark soldiers in the film to break like obsidian shards, which matches the Dark Fairy at the end of the movie. So it was an iteration of something else. When the Queen breaks into ravens they are dark and shiny. The ravens fall into a puddle of black oil and then she comes out of that. Everything has that type of look to it. It also transferred to her actual wardrobe – her crown and the suit of armor at the end.”
