Metro-Goldwyn-Mayer cartoon studio in the context of "William Hanna"

Tom and Jerry (also known as Tom & Jerry) is an American animated media franchise and series of comedy short films created in 1940 by William Hanna and Joseph Barbera. Best known for its 161 theatrical short films produced by Metro-Goldwyn-Mayer, the series centers on the rivalry between a cat named Tom and a mouse named Jerry. Many shorts also feature several recurring characters.

Created in 1940 as the MGM cartoon studio struggled to compete with Walt Disney Productions and Leon Schlesinger Productions, Tom and Jerry's initial short-film titled Puss Gets the Boot proved successful in theaters and garnered an Academy Award nomination for Best Short Subject (Cartoon). Hanna and Barbera later directed a total of 114 Tom and Jerry shorts for its initial MGM run from 1940 to 1958. During this time, they won seven Academy Awards for Best Animated Short Film, tying for first place with Walt Disney's Silly Symphonies with the most awards in the category. After the MGM cartoon studio closed in 1957, MGM revived the series with Gene Deitch directing an additional thirteen Tom and Jerry shorts for Rembrandt Films in Czechoslovakia, from 1961 to 1962. Tom and Jerry became the highest-grossing animated short-film series of that time, overtaking Looney Tunes. Chuck Jones produced another 34 shorts with Sib Tower 12 Productions between 1963 and 1967. Five more shorts have been produced since 2001, making a total of 166 shorts.

William H. Thompson (July 8, 1913 – July 15, 1971) was an American radio personality and voice actor, whose career stretched from the 1930s until his death. He was a featured comedian playing multiple roles on the Fibber McGee and Molly radio series, and was the voice of Droopy in most of the Metro-Goldwyn-Mayer cartoon studio theatrical cartoons from 1943 to 1958.

Thomas Jasper Cat Sr., known simply as Tom, is an American cartoon character and one of the two titular main protagonists (the other being Jerry Mouse) in Metro-Goldwyn-Mayer's series of Tom and Jerry theatrical animated short films. Created by William Hanna and Joseph Barbera, he is a grey-blue and white anthropomorphic (but usually silent) domestic short haired tuxedo British cat who first appeared in the 1940 MGM animated short Puss Gets the Boot. The cat was initially known as "Jasper" during his debut in the short; however, beginning with his next appearance in The Midnight Snack he was known as "Tom" or "Thomas".

Gerald Jinx Mouse, known simply as Jerry, is an American character and one of the two titular characters in Metro-Goldwyn-Mayer's series of Tom and Jerry theatrical animated short films and other animated media, usually acting as the protagonist opposite his rival Tom Cat. Created by William Hanna and Joseph Barbera, Jerry is an anthropomorphic (but usually silent) brown house mouse, who first appeared in the 1940 MGM animated short Puss Gets the Boot.

The character was not referred to by name in his debut cartoon; Hanna said that the mouse's original name as "Jinx", while Barbera claimed the mouse went unnamed in his first appearance. A 1940 article from MGM's Short Story magazine, however, would refer to the character as "Pee-Wee".

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.
