The cartoon series, Merrie Melodies, was posing a problem for its producers because of its lack of popular characters, unlike its competitor, Walt Disney, who had a bevy of lovable personalities. The makers of the Looney Tunes episodes set about correcting that gap in March 1935's "I Haven't Got a Hat" by introducing a new set of animated characters they hoped would rejuvenate the series. One figure introduced in the cartoon especially stood out, and has remained as a mainstay to the Warner Brothers-affiliated series, Porky Pig.
Producer Leon Schlesinger had been selling his Looney Tunes to Warner Brothers in the early 1930s, and complemented those cartoons by originating his new 'Merrie Melodies' in 1931 as an answer to Walt Disney's "Silly Symphonies." The public became enamored with the 'Merrie Melodies,' with its musical-based themes. What it was lacking, however, was a nondescript cast. Director Friz Freleng, motivated by a suggestion from Schlessinger, gathered his artists to produce five new personalities in "I Haven't Got a Hat": Little Kitty, Oliver Owl, Ham and Ex, and Porky Pig. In addition, Beans the Cat shifted over to 'Merrie Melodies' from the Looney Tunes to replace the boy Buddy. All the newbies in the cartoon were each introduced in Miss Cud's schoolroom by the teacher. Porky is the first student to go in front of the class, reciting the poem 'Paul Revere's Ride,' talking with a stutter and seen without his pants.
Schlessinger's long range plan was to create a consistent line of characters similar to the 'Our Gang' series. His idea lasted a mere two years. Except for Porky, all the characters whom were introduced in "I Haven't Got a Hat," including potential super star Beans the Cat, dropped off the screen. Porky was a fan favorite immediately after his debut. The pig was voiced by Joe Dougherty, a stutterer himself. Trouble was Dougherty hadn't been able to control his stutter in the narration booth, taking an inordinate amount of time to finally nail Porky's lines. Dougherty was eventually replaced by Mel Blanc, who stepped in for Porky in 1937.
