Up

Up is a 2009 American animated adventure comedy-drama film directed by Pete Docter and written by Bob Peterson and Docter. Produced by Pixar Animation Studios for Walt Disney Pictures, the film centers on Carl Fredricksen (voiced by Ed Asner), an elderly widower who, by attaching numerous helium balloons to his house, travels to South America with youngster Russell (voiced by Jordan Nagai) in order to fulfill a promise that he made to his late wife. Along the way, they befriend a talking dog (voiced by Peterson) as well as an exotic bird and encounter Carl's childhood idol Charles Muntz (voiced by Christopher Plummer), who has sinister plans to capture the bird.

Originally titled Heliums, Docter conceived the outline for Up in 2004 based on fantasies of escaping from life when it became too irritating. He and eleven other Pixar artists spent three days in Venezuela for research and inspiration. The designs of the characters were caricatured and stylized considerably, and animators were challenged with creating realistic cloth. Composer Michael Giacchino composed the film's score. It was Pixar's first film to be presented in 3D format.
