Snow White and the Seven Dwarfs is the movie that started Disney’s reign in the world of animation, and it almost expanded with two movies that would have solved three big mysteries about the main characters. In 1937, Walt Disney Pictures brought Snow White and the Seven Dwarfs, the first cel-animated feature film and the first animated movie produced in the United States. Snow White and the Seven Dwarfs quickly earned a place in animation history, and it set the example for subsequent Disney animated movies, particularly those starring female characters.
