Question: Which film was released first, The Three Caballeros or Aliens of the Deep?
Context: This is a list of animated package films.  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. Panchito Pistoles is a cartoon character drawn as an anthropomorphized rooster.  He appeared in the film "The Three Caballeros".  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. South of the Border with Disney is a 1942 Disney short documentary film.  It was shot in the same occasion "Saludos Amigos" was, when Walt Disney and a group of eighteen artists, musicians and writers went to South America looking for inspirations for a movie.  While "Saludos Amigos" is the result of this voyage, alternating animated shorts to the sequences from the travel that inspired them, "South of the Border with Disney" is more of a behind-the-scenes documentary showing only the travel and the genesis of cartoons not only for "Saludos Amigos" and "The Three Caballeros", but also some others used in later occasions.  The most notable example is a female Armadillo used for a 1943 Pluto cartoon, "Pluto and the Armadillo".  Film also includes some pencil test animation. Saludos Amigos (Spanish for "Greetings, Friends") is a 1942 American live-action animated package film produced by Walt Disney and released by RKO Radio Pictures.  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". Machine Gun Mama is a 1944 American musical comedy film directed by Harold Young.  It was PRC's attempt to feature a comedy team to compete with Universal's Abbott and Costello and Paramount's Road to ... movies and their entry in the Good Neighbor Policy film genre of the time where the United States presented both a positive image to Latin and South America as well as stimulating American tourism to the region.  Harold Young had also directed the live action portions of Walt Disney's "The Three Caballeros". The Three Caballeros is a 1944 American live-action animated musical package film produced by Walt Disney and released by RKO Radio Pictures.  The film premiered in Mexico City on December 21, 1944.  It was released in the United States on February 3, 1945 and in the UK that March.  The seventh Disney animated feature film, the film plots an adventure through parts of Latin America, combining live-action and animation.  This is the second of the six package films released by Walt Disney Productions in the 1940s, following "Saludos Amigos" (1942). 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). Walt & El Grupo is a 2008 documentary film written and directed by Theodore Thomas.  A presentation of Walt Disney Family Foundation Films, the film tells the story of Walt Disney's 1941 U.S. Government sponsored trip to South America where he and a group of artists gathered material which would be used to create two of Disney's animated feature films, "Saludos Amigos" and "The Three Caballeros". Melody Time (working title All in Fun) is a 1948 American live-action animated film and the 10th theatrically released animated feature produced by Walt Disney.  It was released to theatres by RKO Radio Pictures on May 27, 1948.  Made up of several sequences set to popular music and folk music, the film is, like "Make Mine Music" before it, the popular music version of "Fantasia" (an ambitious film that proved to be a commercial disappointment upon its original theatrical release).  "Melody Time", while not meeting the artistic accomplishments of "Fantasia", was mildly successful.  It is the fifth Disney package film following "Saludos Amigos", "The Three Caballeros", "Make Mine Music", and "Fun and Fancy Free". Aliens of the Deep is a 2005 documentary film, directed in part by James Cameron alongside fellow cameraman and friend Steven Quale, who would go on to direct "Final Destination 5" six years later, and filmed in the IMAX 3D format.  It was produced by Walden Media and Walt Disney Pictures.  Cameron teams with NASA scientists to explore the Mid-Ocean Ridges, submerged chains of mountains in the Atlantic and Pacific oceans that are home to some of the planet's more unusual forms of life.
