The Disney Package Film Era (also known as the Disney Wartime Era) refers to an era of the Disney Animated Canon during and immediately after World War II, when Walt Disney Productions temporarily ceased producing full-length animated features and instead produced package films.
After the release of Bambi, Disney's production of full-length animated features was temporarily suspended. Given the financial failures of some of the recent features and World War II cutting off much of the overseas cinema market, the studio's financiers at the Bank of America would only loan the studio working capital if it temporarily restricted itself to shorts production. Then in-production features were therefore put on hold until after the war. Other issues affecting the studio at the time included the drafting of several Disney animators to fight in World War II, and the necessity for the studio to focus on producing wartime content for the U.S. Army, particularly military training and civilian propaganda films. From 1942 to 1943, 95 percent of the studio's animation output was for the military. During the war, Disney produced the live-action/animated military propaganda feature Victory Through Air Power (1943), and a series of Latin culture-themed shorts resulting from the 1941 Good Neighbor trip were compiled into two features, Saludos Amigos (1942/1943) and The Three Caballeros (1944/1945).
Saludos and Caballeros set the template for several other 1940s Disney releases of "package films": low-budgeted films composed of animated short subjects with animated or live-action bridging material. These films were Make Mine Music (1946), Fun and Fancy Free (1947), Melody Time (1948), and The Adventures of Ichabod and Mr. Toad (1949). The studio also produced two features, Song of the South (1946) and So Dear to My Heart (1948/1949), which used more expansive live-action stories which still included animated sequences and sequences combining live-action and animated characters.
