Up is a comedy adventure about Carl Fredricksen (Edward Asner), a retired 78-year-old balloon salesman who meets and later marries a girl named Ellie. Growing up in a small Midwestern town, Ellie has always dreamed of visiting South America. Unfortunately, she died before she got a chance. In hopes of fulfilling his promise to Ellie, Carl uses 10,000 balloons to make his house fly and sets off for South America. He unknowingly takes a chubby eight-year-old Wilderness Explorer named Russell along for the ride and the duo match up for one thrilling adventure around the earth.
The film is directed by Pete Docter (the director of Monsters Inc.) and features voices of Edward Asner, Christopher Plummer and Jorgan Nagai. Up premiered by opening the 2009 Cannes Film Festival, which was the first animated film to do so. The film has received overwhelmingly positive reviews, and grossed over $683 million worldwide, making it Pixar's second most commercially successful film, after Finding Nemo.
