Carl Fredricksen

The San Peoples Land 2 (film)
After surviving a thunderstorm, the house lands near a ravine facing Paradise Falls. Carl and Russell harness themselves to the still-buoyant house and begin to walk it around the ravine, hoping to reach the falls before the balloons deflate. They later befriend a tall, colorful flightless bird whom Russell names "Kevin" who is trying to reach her chicks and a dog named Dug, who wears a special collar that allows him to speak.
 * If Carl is 78 years old in 2009, and if he was 9 in 1939, he was either born in 1930 or 1929.
 * Carl wore the same style of glasses at every age.
 * Carl's personality may be a reference to Shel Silverstein's The Giving Tree.
 * To lift a house such as Carl's (and rip it loose from the utility pipes/cables anchoring it) would, in reality, require vastly more balloons than are shown.
 * An unpowered airship (such as Carl's house) would not be steerable; it would go wherever the wind goes.
 * Both these last two points were Pixar deciding to go for believable rather than realistic.
 * Although Carl doesn't have his own musical theme, Ellie's theme plays whenever he thinks about her, and also plays against Muntz's theme during the climax.
 * Carl is the second oldest protagonist of a Pixar film, the oldest being WALL-E, as he has been "alive" for more than 700 years (the movie WALL-E takes place in 2805, and Up takes place in 2009 the year it was released).
 * Carl is also the second Pixar protagonist to lose his love interest after Marlin from Finding Nemo.
 * In an interview with the director of Up, Pete Docter, he has stated that the letter, the letter Andy has addressed from Carl and Ellie in Toy Story 3, was signed to person by the name of Emma Jean who is Carl's previous love interest before Ellie but are now close friends who frequently go out together.[1]

Carl and Russell encounter a pack of dogs led by Alpha and are taken to Dug's master, who turns out to be an elderly Thunder Muntz. Muntz invites Carl and Russell aboard his dirigible, where he explains that he has spent the years since his disgrace searching Paradise Falls for the giant bird. When Russell innocuously notes the bird's similarity to Kevin, Muntz becomes hostile, prompting the pair to flee with Kevin and Dug. Muntz eventually catches up with them and starts a fire beneath Carl's house, forcing Carl to choose between saving it or Kevin. Carl rushes to put out the fire, allowing Muntz to take the bird. Carl and Russell eventually reach the falls, but Russell is angry with Carl over his decision to save his house instead of Kevin.

Settling into his home, Carl looks through Ellie's childhood scrapbook, seeing that it actually has many more photos of their lives in it than he thought, and finds a note from Ellie thanking him for the "adventure" and encouraging him to go on a new one. Reinvigorated, he goes to find Russell, only to see him sailing off on some balloons to save Kevin. Carl empties the house of furniture and possessions and pursues him.

Russell is captured by Muntz, but Carl manages to board the dirigible in flight and free both Russell and Kevin, having a fight with Muntz. Muntz pursues them around the airship, finally cornering Dug, Kevin, and Russell inside Carl's tethered house. Carl lures Kevin out through a window and back onto the airship with Dug and Russell clinging to her back, just as Muntz is about to close in. Muntz leaps after them, only to snag his foot on some balloon lines and fall to his death. Snapped from its tether, the house descends out of sight through the clouds, which Carl accepts as being for the best.

Carl and Russell reunite Kevin with her chicks, then fly the dirigible back to the city. When Russell's father misses his son's Senior Explorer ceremony, Carl presents Russell with his final badge: the grape soda cap that Ellie gave to Carl when they first met, to the applause of who appears to be Russell's mother in the audience. The two then enjoy some ice cream together, sitting on the curb outside the shop as Russell and his father used to do, with the dirigible parked nearby. Meanwhile, Carl's house is shown to have landed on the cliff beside Paradise Falls, as promised to Ellie.
