Brother Bear is a 2003 American animated musical fantasy comedy-drama film produced by Walt Disney Feature Animation and released by Walt Disney Pictures. It was directed by Aaron Blaise and Robert Walker (in their feature directorial debuts) and produced by Chuck Williams, from a screenplay written by Tab Murphy, Lorne Cameron, David Hoselton, and the writing team of Steve Bencich and Ron J. Friedman. The film stars the voices of Joaquin Phoenix, Jeremy Suarez, Rick Moranis, Dave Thomas, Jason Raize (in his only film role), and D.B. Sweeney. Brother Bear follows an Alaska native boy named Kenai as he pursues a bear and kills it, but the Spirits, incensed by this unnecessary death, change Kenai into a bear himself as punishment. In order to be human again, Kenai must travel to a mountain where the Northern lights touch the earth.

The film was the third and final Disney animated feature produced primarily by the Feature Animation studio at Disney-MGM Studios in Orlando, Florida; the studio was shut down in March 2004, not long after the release of this film in favor of computer-animated features. The film, which was released in the United States on November 1, 2003, received mixed reviews from critics and received a nomination for Best Animated Feature at the 76th Academy Awards, losing to Pixar's Finding Nemo. The film grossed $250 million against a $46 million budget. A direct-to-video sequel, Brother Bear 2, was released on August 29, 2006.
