Up

Up is a 2009 American 3D computer-animated comedy-drama buddy adventure 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, as well as the story with Tom McCarthy, with music composed by Michael Giacchino.

Docter began working on the story in 2004, which was 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.

Up was Pixar's first film to be presented in Disney Digital 3-D. It was released on May 29, 2009, and opened the 2009 Cannes Film Festival, becoming the first animated and 3D film to do so. The film grossed over $735 million, and received universal acclaim, with critics commending the humor and heart of the film. Asner's vocal performance and Michael Giacchino's score were praised, as was the montage of Carl and his wife Ellie aging together. The film received five Academy Award nominations, including Best Picture, making it the second animated film in history to receive such a nomination, following Beauty and the Beast (1991).
