After joining The Greyboy Allstars following the dissolution of his band The Origin, Andrews fell into film score composition by chance when The Greyboy Allstars were asked to score Jake Kasdan's first feature Zero Effect and worked on the music for the highly regarded (though short-lived) TV series, Freaks and Geeks. In 2000, Richard Kelly commissioned him to do the soundtrack for the film Donnie Darko. Its original score album went on to sell over 100,000 copies (in part because of Andrews's remake of Tears for Fears' "Mad World", featuring Gary Jules),[2] and Andrews became a composer to watch. He has since gone on to compose scores for the movies Out Cold, Nothing, Cypher, Orange County, My Suicidal Sweetheart, Me and You and Everyone We Know, The TV Set, a segment of Paris, je t'aime, Unaccompanied Minors, and Walk Hard: The Dewey Cox Story.
