Factual error: After trying to get his balloon back, Carl Jr. falls and breaks his arm. The ambulance that picks him up has a modern-day electronic siren, when in the 30's it would be a mechanical siren and would be much smaller.

Directed by: Pete Docter, Bob Peterson

Continuity mistake: When Russel is complaining, when he says "Zoology" his face is covered in dirt. When Carl tells him that he can do his business in the bushes, he is instantly clean. http://www.youtube.com/watch?v=lOjhfcBNZW8.
Carl: Russell, if you don't get up, the tigers will eat you.
Russell: There aren't any tigers in South America. Zoology.
Trivia: Nicknamed Pixar's lucky charm, John Ratzenberger is the only actor with parts in all of the studio's films. In Up, he voices the construction foreman who urges Carl to sell his home.
