From 1929 to 1939, Walt Disney produced a series of 76 short animated films. "Three Little Pigs," which was released in 1933, marked the first example of the technical innovation and experimentation whose culmination would make possible Disney's future work, and the beginning of an era of feature films with recognizable characteristics for which Disney would become known. "Three Little Pigs" pioneered in the areas of narrative, character development, color, and music and sound integration; Disney set high goals for itself and achieved them in this short film.
