 "The Wearing of the Grin" was the final cartoon featuring Porky Pig as the only major recurring character.Porky had been Warner Bros. animation’s first major star until had been supplanted first by Daffy Duck (a phenomenon that was foreshadowed in film form in Friz Freleng’s "You Ought to Be in Pictures"), and later by Bugs Bunny.As this had progressed, Porky starred in fewer solo cartoons.
