Voice cast / Szereplők - Hangok

• Ed Asner as Carl Fredricksen:
  A salesman and widower who flies his house to Paradise Falls to fulfill a childhood dream he shared with his late wife Ellie. 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.^[10]) 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".  Jordan Nagai as Russell:
  • Jeremy Leary as Young Carl Fredricksen
• 
  A Wilderness Explorer who is trying to earn a merit badge for "Assisting the Elderly" and becomes a stowaway on Carl's house as it flies to Paradise Falls. Throughout most of the film, he makes several comments to Carl that suggest that Russell's father and mother are no longer together.^[12] Russell's design was based on Pixar animator Peter Sohn,^[13] who is Korean-American. The Pixar employees frequently sketch each other during meetings, and a drawing of Sohn became the model for Russell.^[14] Docter auditioned 400 boys in a nationwide casting call for the part.^[15] Nagai, who is Japanese American,^[16] 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.^[17] Nagai was eight years old when cast.^[15] 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.^[11] East Asian Americans have positively noted Pixar's first casting of an East Asian lead character,^[18][19] in contrast to the common practice of casting non-East Asians in East Asian parts,^[20] particularly in the role of an "all-American" boy without any stereotypes typically seen with East Asian characters, such as martial arts.^[21]
• Christopher Plummer as Charles F. Muntz:
  A renowned explorer who claims to have discovered a species of giant bird and has not been seen since vowing to bring a live specimen from South America. The name of his airship, the Spirit of Adventure, may have been inspired by Charles Lindbergh's airplane, Spirit of St. Louis.^[22] In various interviews, Pete Docter has mentioned Howard Hughes and real-life adventurers Charles Lindbergh and Percy Fawcett as inspirations for Muntz.^[23]
• 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.^[22] 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.^[22]
• 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. In either voice, Alpha has a roundabout speech pattern that causes his sentences to be longer than necessary.

• Pete Docter as:

• Kevin:
  The "Beast of Paradise Falls".
• Campmaster Strauch:
  Russell's scout leader, seen at the end of the film.

• Elizabeth Docter as Ellie:
  A bold and adventurous young girl who meets Carl in their childhood when he walks into her home and eventually marries him as an adult. The voice actor is the director's daughter,^[24] who also provided some of the drawings shown by Ellie. Elizabeth only voiced Ellie as a child, as the adult Ellie had no spoken lines.
• Delroy Lindo as Beta: A Rottweiler and one of Muntz's dogs.
• Jerome Ranft as Gamma: A Bulldog and one of Muntz's dogs.
• John Ratzenberger as Tom: The construction worker who asks if Carl is ready to sell his house
• David Kaye as the newsreel announcer.
• Danny Mann as Steve: A construction worker whom Carl injures after he accidentally damages Carl's mailbox
• Mickie McGowan as Edith: A police officer who brings Carl home after his court appointment.
• Don Fullilove and Jess Harnell as George and A.J.: Two nurses who work at Shady Oaks Retirement Village.
