The Three Little Pigs and its theme song were flyaway successes when it was released, with theatre owners extending the cartoon's run for months and a popular merchandising line springing up; it is almost certainly the best known Silly Symphony, and quite possibly the single best known Disney short. It is widely recognised as a milestone in cartoon characterisation - while earlier shorts often had solid stories, series stars tended to be little more than vehicles for strings of sight gags. The Three Little Pigs, however, has a plot and characters that mesh together perfectly - and a catchy song to boot.
By popular demand, three sequels were produced. The series stretched the basic formula to breaking point, though; the fact that Fiddler and Fife never seemed to learn their lesson made them a tad annyoing. As Walt Disney himself put it, you can't top pigs with pigs.
