Quantum Quest: A Cassini Space Odyssey (originally titled as 2004: A Light Knight's Odyssey) is a 2010 animated educational sci-fi adventure film, written by Harry 'Doc' Kloor and directed by Kloor and Dan St. Pierre, as a science fiction film that takes the viewer on an atomic adventure in space. The voice cast originally included Christian Slater, John Travolta, Samuel L. Jackson, Sarah Michelle Gellar, Michael York, and James Earl Jones, but the cast changed in 2008, reflecting a new script that detailed a host of new discoveries made by the Cassini–Huygens mission to Saturn. Using a cast of major actors to provide their voices to the characters, the film was initiated by JPL/NASA through a grant from Jet Propulsion Lab via the international Cassini-Huygens mission to Saturn.
