Up is a 2009 American computer-animated film produced by Pixar Animation Studios and released by Walt Disney Pictures. The film was directed by Pete Docter, co-directed by Bob Peterson (in his feature directorial debut), and produced by Jonas Rivera. Docter and Peterson also wrote the film’s screenplay and story, with Tom McCarthy co-writing the latter. The film stars the voices of Ed Asner, Christopher Plummer, Jordan Nagai, and Peterson. The film centers on elderly widower Carl Fredricksen (Asner) and Wilderness Explorer Russell (Nagai), who go on a journey to South America in order to fulfill a promise that Carl made to his late wife Ellie. Along the way, they meet a talking dog named Dug (Peterson), and encounter a giant bird named Kevin, who is being hunted by the explorer Charles Muntz (Plummer).
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 3D format.
Up debuted at the 62nd Cannes Film Festival on May 13, 2009, and was released in the United States on May 29. The film received critical acclaim from critics for its screenplay, animation, characters, themes, narrative, Asner's vocal performance, Michael Giacchino's musical score, and the opening sequence. 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, finishing its theatrical run as the sixth-highest-grossing film of 2009. Up was nominated for five awards at the 82nd Academy Awards, winning two, and received numerous accolades.
