Disney’s Snow White and the Seven Dwarfs is regarded as one of the greatest animated movies ever made, but the movie could have looked completely different had it not been for one short cartoon released three years prior. Released in 1937, it made history by not only being Walt Disney’s first full-length animated movie, but also the first animated movie produced in the United States. The movie was adapted from the 1812 Brothers Grimm fairy tale, and while there are several notable differences between the book and movie, it is still regarded as one of the best adaptations.
