Which Disney animated musical was the first feature-length film produced by Walt Disney Productions?

Snow White and the Seven Dwarfs was the first feature-length animated film produced by Walt Disney Productions.

Released in 1937, the film adapted the Brothers Grimm fairy tale about a princess pursued by her jealous stepmother. Walt Disney took a major financial risk by developing a full-length animated feature when many observers dismissed the project as “Disney’s Folly.” Its success established animation as a viable feature-film medium.

The film combines spoken dialogue, orchestral scoring, and songs including “Someday My Prince Will Come” and “Heigh-Ho.” It is sometimes described as the first animated feature, but that wording needs context: earlier animated features had been made elsewhere, including Argentina’s El Apóstol in 1917, which is lost. Snow White was the first widely distributed feature-length animated film and the first from Disney.
