Up is a 2009 American computer-animated film produced by Pixar Animation Studios and released by Walt Disney Pictures. The film centers on an elderly widower named Carl Fredricksen (Ed Asner) and an earnest boy named Russell (Jordan Nagai); by tying thousands of balloons to his house, Carl sets out to fulfill his dream to see the wilds of South America and complete a promise made to his late wife, Ellie. The film was directed by Pete Docter and co-directed by Bob Peterson, who also wrote the film's screenplay with Docter, as well as the story with Tom McCarthy. The music was composed by Michael Giacchino, who had also composed music for The Incredibles and Ratatouille. Originally titled Heliums, Docter conceived the outline for Up in 2004 based on fantasies of escaping from life when it becomes too irritating. He and eleven other Pixar artists spent three days in Venezuela gathering research and inspiration. The designs of the characters were caricatured and stylized considerably, and animators were challenged with creating realistic cloth. It was Pixar's first film to be presented in Disney Digital 3-D.Up debuted at the 62nd Cannes Film Festival on May 13, 2009, and was released in theaters in the United States on May 29. It was well received by the media for its characters, themes, narrative, Asner's vocal performance, and Giacchino's score, as was the montage of Carl and his wife Ellie growing old together. Organizations like the National Board of Review and American Film Institute named Up as one of the top 10 films of 2009. It earned $735.1 million worldwide, and became the sixth highest-grossing film of 2009. Up earned five nominations at the 82nd Academy Awards, winning two for Best Animated Feature and Best Original Score, and also received numerous accolades.
