 It is the sixth Disney animated feature film and the first of the six package films produced by Walt Disney Productions in the 1940s.
 Set in Latin America, it is made up of four different segments; Donald Duck stars in two of them and Goofy stars in one.
 It also features the first appearance of José Carioca, the Brazilian cigar-smoking parrot.
 "Saludos Amigos" was popular enough that Walt Disney decided to make another film about Latin America, "The Three Caballeros", to be produced two years later.
 "Saludos Amigos" premiered in Rio de Janeiro on August 24, 1942.
 It was released in the United States on February 6, 1943.
 At 42 minutes, it is Disney's shortest animated feature to date.
 It garnered positive reviews and was theatrically reissued in 1949, when it was shown on a double bill with the first reissue of "Dumbo".

 There are two types of package films — a film with little or no new animation; usually there is only new bridge animation to link older theatrical/TV shorts together, for example "Daffy Duck's Quackbusters".
 The other type has all-new animation and might not always feature bridge animation. "
Melody Time" doesn't feature bridge animation, but "The Three Caballeros" does.
 Home video releases of older theatrical and TV shorts or TV series are usually released as compilations and might therefore be thought of as packaged, but are usually not considered as such.

 Later he appeared in several Disney comics, including Don Rosa's "The Three Caballeros Ride Again" and "The Magnificent Seven (Minus 4) Caballeros".
 Panchito was the only one of the Three Caballeros to never appear in "Saludos Amigos", as he did not yet exist when the 1942 film was released before he first appeared in the 1944 film.
Manuel Esperón González (August 3, 1911 – February 13, 2011) was a Mexican songwriter and composer.
 He wrote many songs for Mexican films, including "¡Ay, Jalisco, no te rajes!
" for the 1941 film of the same name, "Cocula" for "El Peñón de las Ánimas" ("The Rock of Souls") (1943), and "Amor con amor se paga" for "Hay un niño en su futuro" (1952).
 Other Esperón compositions have become Latin standards such as "Yo soy mexicano", "Noche plateada" and "No volveré", which was used in the first episode of the 2001 soap opera "El juego de la vida".
 Among other performers, Chavela Vargas, Pedro Infante, Los Panchos, and Jorge Negrete have made his songs well-known.
 His fame in the USA derives from when his song "The Three Caballeros" was used in the Disney film "The Three Caballeros" (1944).
