Using special tools called "shapers," the animators were able to achieve sophisticated facial and body movements by applying interacting layers of bone, muscle fat, skin and, finally, hair and clothing or, as in the case of the Donkey, fur.
There are also advances in the creation of rich, organic natural environments; clothing that moves, wrinkles and reacts to light like real-life fabric; fire; and fluids of different viscosities, achieved using PDI/DreamWorks' Fluid Animation System (FLU), which won an Academy Award® for Technical Achievement in 1999.

Steig's story of an ogre who sets out into the world to find adventure first came to the attention of producer John H. Williams... "Even as an adult, I thought Shrek was outrageous, irreverent, iconoclastic, gross, and just a lot of fun. He was a great movie character in search of a movie."
Screenwriters Ted Elliott & Terry Rossio, who had previously worked with Katzenberg and Warner on Antz (1998), collaborated with Joe Stillman and roger s.H. Schulman to adapt the story into an animated action adventure, told with humor and heart, under the direction of Andrew Adamson and Vicky Jenson.
