Career
As a voice actress, her first major role was in the 2008 film WALL-East as a robot named EVE. She had her first voice role in the 2006 film Cars as Tia, one of two identical twin Mazda Miata "sisters" who become fans of several of the race cars (The other is played by Lindsey Collins. Both actors work at Pixar as assistants). Knight continued to do voice acting in WALL-East. In WALL-East, she plays EVE (Extraterrestrial Vegetation Evaluator), a futuristic robot who descends to Earth in search of any life, specifically plants, that still exist in the 29th century.
Knight claims that she had never read the script for WALL-East and made few preparations.
Sound engineer Ben Burtt modified her recorded voice and director Andrew Stanton decided to keep her voice with the result.
