Elmer Fudd in the context of "Mel Blanc"

Looney Tunes is an American media franchise produced and distributed by Warner Bros. The franchise began as a series of animated short films that originally ran from 1930 to 1969, alongside its spin-off series Merrie Melodies, during the golden age of American animation. Following a revival in the late 1970s, new shorts were released theatrically as recently as 2014. The two series introduced a large cast of characters, including Bugs Bunny, Daffy Duck, Elmer Fudd and Porky Pig. The term Looney Tunes has since been expanded to also refer to the characters themselves.

Looney Tunes and Merrie Melodies were initially produced by Leon Schlesinger and animators Hugh Harman and Rudolf Ising from 1930 to 1933. Schlesinger assumed full production from 1933 until he sold his studio to Warner Bros. in 1944, after which it was renamed Warner Bros. Cartoons. The Looney Tunes title was inspired by that of Walt Disney's Silly Symphonies. The shorts initially showcased musical compositions owned by Warner's music publishing interests through the adventures of such characters as Bosko and Buddy. However, the shorts gained a higher profile upon the debuts of directors Tex Avery, Friz Freleng, Chuck Jones, Bob Clampett, and Robert McKimson, and voice actor Mel Blanc later in the decade. Porky Pig and Daffy Duck became the featured Looney Tunes characters, while Merrie Melodies featured one-shot cartoons and minor recurring characters.

Bugs Bunny is a cartoon character created in the late 1930s at Warner Bros. Cartoons (originally Leon Schlesinger Productions) and voiced originally by Mel Blanc. Bugs is best known for his featured roles in the Looney Tunes and Merrie Melodies series of animated short films, produced by Warner Bros. Early iterations of the character first appeared in Ben Hardaway's Porky's Hare Hunt (1938) and subsequent shorts before Bugs's definitive character traits debuted in Tex Avery's A Wild Hare (1940). Bob Givens, Chuck Jones, and Robert McKimson are credited for defining Bugs's visual design.

Bugs is an anthropomorphic gray-and-white rabbit or hare who is characterized by his flippant, insouciant personality, his Brooklyn accent, and his catchphrase "Eh... What's up, doc?". He is typically portrayed as a trickster, outwitting foes like Elmer Fudd and Yosemite Sam as well as various authority figures and criminals. He develops a friendly rivalry with Daffy Duck. Through his popularity during the golden age of American animation, Bugs became an American cultural icon and Warner Bros.' official mascot.

Frederick Bean "Tex" Avery (/ˈeɪvəri/; February 26, 1908 – August 26, 1980) was an American animator and voice actor. He was known for directing and producing animated cartoons during the golden age of American animation. His most significant work was for the Warner Bros. and Metro-Goldwyn-Mayer studios, where he was crucial in the creation and evolution of famous animated characters such as Bugs Bunny, Daffy Duck, Porky Pig and Elmer Fudd for Warner Bros. and Droopy, Butch Dog, Screwy Squirrel, The Wolf, Red Hot Riding Hood, and George and Junior for Metro-Goldwyn-Mayer.

He gained influence for his technical innovation, directorial style, and brand of humor that appealed especially towards adults. Avery's attitude toward animation was opposite that of Walt Disney and other conventional family cartoons at the time. Avery's cartoons were known for their essentially darker, sarcastic, ironic, absurdist, irreverent, and sometimes sexual tone in nature. They focused on visual gags, meta humor, physically impossible gags, social satire, surrealist humor, rapid pacing, racial stereotypes, and violent slapstick occurring around brash, outlandish characters who broke the fourth wall, stating that cartoons are meant to do anything.
