This is a listing of all the animated shorts released by Warner Bros. under the Looney Tunes and Merrie Melodies banners between 1930 and 1939, plus the 1929 pilot film which was used to sell the Looney Tunes series to Leon Schlesinger and Warner Bros.. A total of 270 shorts were released during the 1930s.
Looney Tunes and Merrie Melodies cartoons were each assigned identification numbers that would appear directly on title cards shown at the beginning of each short. These numbers included cartoon studio production numbers, Vitaphone release numbers, Blue Ribbon re-release numbers, and MPAA certificate numbers. Not all of these types of numbers were listed in the title cards of every cartoon and the numbering schemes were sometimes inconsistent. For example, until 1943 cartoons listed Vitaphone release numbers but not cartoon studio production numbers. These release numbers, in turn, increased to 9999 but then restarted at 1. Complicating matters was the Warner Bros. Blue Ribbon re-release program, in which some cartoons were re-released in theaters with new title cards that often removed original production credits and substituted production or release numbers with new re-release numbers. In many cases, the Blue Ribbon releases are the only available prints of a cartoon, making it challenging to discern these cartoons' correct original production information.
In the list below, Blue Ribbon re-release numbers are noted with "BR" and Vitaphone release numbers are noted with "VP".
Bosko, the Talk-Ink Kid, a 1929 live-action short film produced to sell a series of Bosko cartoons, was not released to theaters, and therefore not seen by a wide audience until 71 years later on Cartoon Network's television special Toonheads: The Lost Cartoons on March 12, 2000, although in an edited form. The film was produced in May 1929, directed by Hugh Harman and Rudolf Ising. In the film, a cartoonist (portrayed in live action by Rudolph Ising) draws Bosko, who comes to life. Bosko speaks, sings, dances and plays the piano before the cartoonist sucks him into his ink pen and pours him back into the inkwell. Bosko pops out of the bottle and promises to return.
