<P> The repentant Carl goes outside, only to see Russell sailing off with some balloons and a propulsive leaf blower to rescue Kevin, telling Carl that he wants to save her with or without Carl's help . By throwing out his furniture and keepsakes, Carl lightens the house enough to follow . Russell is captured by Muntz, but Carl manages to board the dirigible, tether the house, and free Russell and Kevin . Dug inadvertently saddles Alpha with the cone of shame and becomes the dogs' new leader . Muntz, now discovering their plans immediately thanks to Russell, determinedly pursues them around the airship and manages to disable Carl's house, but snags his foot on some loose balloon lines and falls to his death . The house, having lost too many balloons to fly, descends out of sight through the clouds . </P> <P> Carl and Russell reunite Kevin with her chicks and fly the dirigible back home . Russell receives his Assisting the Elderly badge, and Carl presents Russell with his own badge: a grape soda cap that Ellie gave to Carl when they first met . Meanwhile, Carl's house has landed on the cliff beside Paradise Falls, fulfilling his promise to Ellie . </P> <Ul> <Li> Ed Asner as Carl Fredricksen (Jeremy Leary voiced Carl as a young boy). Docter and Rivera noted Asner's television alter ego, Lou Grant, had been helpful in writing for Carl because it guided them in balancing likable and unlikable aspects of the curmudgeonly character . When they met Asner and presented him with a model of his character, he joked, "I don't look anything like that ." (The appearance of Carl is meant to resemble Spencer Tracy as he appeared in his final film, Guess Who's Coming to Dinner .) They tailored his dialogue for him, with short sentences and more consonants, which "cemented the notion that Carl, post-Ellie, is a disgruntled bear that's been poked awake during hibernation". In Colombia, unexpected publicity for the film was generated due to the uncanny similarity of Carl with Colombian ex-president Julio César Turbay Ayala . </Li> <Li> Christopher Plummer as Charles F. Muntz . The name of his airship, the Spirit of Adventure, may have been inspired by Charles Lindbergh's airplane, Spirit of St. Louis . In various interviews, Pete Docter has mentioned Howard Hughes and real - life adventurers Charles Lindbergh and Percy Fawcett as inspirations for Muntz . </Li> <Li> Jordan Nagai as Russell . Throughout most of the film, he makes several comments to Carl that suggest that Russell's father and mother are no longer together . Russell's design was based on Pixar animator Peter Sohn . Docter auditioned 400 boys in a nationwide casting call for the part . Nagai, who is Japanese American, showed up to an audition with his brother, who was actually the one auditioning . Docter realized Nagai behaved and spoke non-stop like Russell and chose him for the part . Nagai was eight years old when cast . Docter encouraged Nagai to act physically as well as vocally when recording the role, lifting him upside down and tickling him for the scene where Russell encounters Kevin . Asian Americans have positively noted Pixar's first casting of an Asian lead character, in contrast to the common practice of casting non-Asians in Asian parts . </Li> <Li> Bob Peterson as Dug, the Golden Retriever misfit of Muntz's pack of dogs that can all communicate with humans through a device on each of their collars . Peterson knew he would voice Dug when he wrote his line "I have just met you, and I love you," which was based on what a child told him when he was a camp counselor in the 1980s . The DVD release of the film features a short called Dug's Special Mission, which follows Dug just before his first meeting with Carl and Russell . Dug previously appeared in Ratatouille as a shadow on a wall that barks at Remy . <Ul> <Li> Peterson also voiced Alpha, the Doberman Pinscher leader . Pete Docter has stated that Alpha "thinks of himself as Clint Eastwood". Despite his menacing appearance, a frequent malfunction in Alpha's translating collar causes his voice to sound comically high - pitched and squeaky, as if he had been breathing helium . The normal voice for his translator is a resonant, intimidating bass . With both voices, Alpha has a roundabout speech pattern that causes his sentences to be longer than necessary . </Li> </Ul> </Li> <Li> Pete Docter as Kevin, the "Beast of Paradise Falls". Docter also voiced Campmaster Strauch, Russell's scout leader, seen at the end of the film . </Li> <Li> Elizabeth Docter as Ellie . The voice actor is the director's daughter, who also provided some of the drawings shown by Ellie . Elizabeth only voiced Ellie as a child, as adult Ellie had no speaking lines . </Li> <Li> Delroy Lindo as Beta, a Rottweiler and one of Muntz's dogs </Li> <Li> Jerome Ranft as Gamma, a Bulldog and one of Muntz's dogs . Joe Ranft was rumored to voice him; however he died in a car accident in 2005 . </Li> <Li> John Ratzenberger as Tom, the construction worker who asks if Carl is ready to sell his house </Li> <Li> David Kaye as the newsreel announcer </Li> <Li> Danny Mann as Steve, a construction worker whom Carl injures after he accidentally damages Carl's mailbox </Li> <Li> Mickie McGowan as Edith, a police officer who brings Carl home after his court appointment </Li> <Li> Don Fullilove and Jess Harnell as George and A.J., two nurses who work at Shady Oaks Retirement Village </Li> </Ul> <Li> Ed Asner as Carl Fredricksen (Jeremy Leary voiced Carl as a young boy). Docter and Rivera noted Asner's television alter ego, Lou Grant, had been helpful in writing for Carl because it guided them in balancing likable and unlikable aspects of the curmudgeonly character .
