10 surprising ways famous film special effects were made


Pacific Rim

Although it's a film about massive robots fighting giant monsters, Pacific Rim's director, Guillermo del Toro, had very specific reference material for the animation team: Goya's 19th century painting, The Colossus.

The fight scenes in the film were completely computer-generated, but animation director Hal Hickel told us: "That was first image he showed us, The Colossus by Goya, and the first words del Toro spoke to us about Pacific Rim were 'operatic' and 'poetic'." Followed closely by 'smashy' and 'fighty', presumably.
