You know the basic story, the practical hardworking pig builds his house with bricks and mortar; one lazy buddy uses sticks and the other uses straw. Then when the time comes to keep out the Big Bad Wolf everyone heads to the brick house. It's an old fable and Disney wisely altered the original story where the wolf eats the two lazy pigs and is eaten by the remaining pig after falling into boiling water.
"The Three Little Pigs" was the 36th cartoon in Disney's "Silly Symphony" series and came just a year after "Flowers and Trees" forever changed the animation industry by introducing the first Technicolor cartoon. Technicolor was a process where three separate negatives (each a primary color) were combined to produce a color print. It took a while to perfect it for live action so it was first utilized for animation.
"The Three Little Pigs" was the most popular cartoon in history, on many theater marquees it was billed above the feature film. Disney had a two year exclusive on the use of the Technicolor process and had one animator work on giving each pig a distinct personality while another animator created the wolf. Frank Churchill wrote the "Big Bad Wolf" song, which unexpectedly became a monster hit-Disney's first published song. The wolf at the door was considered the symbol of the Depression and the song became a national rallying cry.
Disney would follow it up with three other attempts: "The Big Bad Wolf", "Three Little Wolves", and "The Practical Pig". None were nearly as successful as the original and Walt is said to have repeatedly stated: "You can't top pigs with pigs."
Then again, what do I know? I'm only a child.
