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 United Kingdom that March. The 7th Disney animated feature film, the film, marking the 10th anniversary of Donald Duck, 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). It was also the first feature-length film to incorporate traditional animation with live-action actors.[citation needed] The film is plotted as a series of self-contained segments, strung together by the device of Donald Duck opening birthday gifts from his Latin American friends. Several Latin American stars of the period appear, including singers Aurora Miranda (sister of Carmen Miranda) and Dora Luz, as well as singer and dancer Carmen Molina. The film was produced as part of the studio's goodwill message for Latin America.[3] The film stars Donald Duck, who in the course of the film is joined by old friend José Carioca, the cigar-smoking parrot from Saludos Amigos, who represents Brazil, and later becomes friends with a pistol-packing rooster named Panchito Pistoles, who represents Mexico.
