The Ant Bully is a 2006 American animated fantasy adventure comedy film written and directed by John A. Davis and based on the 1999 children's book of the same name. The film features an ensemble voice cast including Julia Roberts, Nicolas Cage, Meryl Streep, and Paul Giamatti. The story follows Lucas Nickle, a 10-year-old bullied boy who, after attacking the nearby ant colony out of frustration, is shrunk by the ants and is ordered to work amongst them. It was produced by Tom Hanks and Gary Goetzman's Playtone, Davis and Keith Alcorn's DNA Productions, Legendary Pictures in their first animated film, and Warner Bros. Pictures who also distributed.

Released on July 28, 2006, The Ant Bully received mixed reviews from critics and became a box-office failure, grossing $55 million against its $50 million budget. Due to this, many DNA employees were laid off, leading to the studio's closure. This was Ricardo Montalbán's final film role before his death in 2009.
