Academy Award for Best Animated Short Film in the context of 46th Academy Awards

Pluto is an American cartoon character created by Walt Disney and Norm Ferguson. He is a yellow-orange color, medium-sized, short-haired dog with black ears. Unlike most Disney characters, Pluto is not anthropomorphic beyond some characteristics such as facial expression. He is Mickey Mouse's pet. Officially a mixed-breed dog, he made his debut as a bloodhound in the Mickey Mouse cartoon The Chain Gang. Together with Mickey Mouse, Minnie Mouse, Donald Duck, Daisy Duck, and Goofy, Pluto is one of the "Sensational Six"—the biggest stars in the Disney universe. Though all six are non-human animals, Pluto alone is not dressed as a human.

Pluto debuted in animated cartoons and appeared in 24 Mickey Mouse films before receiving his own series in 1937. All together Pluto appeared in 89 short films between 1930 and 1953. Several of these were nominated for an Academy Award, including The Pointer (1939), Squatter's Rights (1946), Pluto's Blue Note (1947), and Mickey and the Seal (1948). One film starring him, Lend a Paw (1941), won the award in 1942. Because Pluto does not speak, his presence relies on physical humor. This made him a pioneering figure in character animation, by expressing personality through animation rather than dialogue.

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.

Sony Pictures Imageworks Inc. (also known as Imageworks) is a Canadian-American visual effects and computer animation studio headquartered in Vancouver, British Columbia and Montreal, Quebec, with an additional office on the Sony Pictures Studios lot in Culver City, California. SPI is a unit of Sony Pictures Entertainment's Motion Picture Group.

The company has been recognized by the Academy of Motion Picture Arts and Sciences winning the Academy Award for Best Visual Effects for their work on Spider-Man 2, as well as the Academy Award for Best Animated Film for Into the Spider-Verse and Academy Award for Best Animated Short Film for The ChubbChubbs!, having also received many other nominations for their work.

Pluto’s Blue Note is a 1947 animated short film produced by Walt Disney Productions that stars Pluto. The film was nominated for the 1948 Academy Award for Best Animated Short Film but lost to Warner Bros.' Tweetie Pie.

Mickey and the Seal is a cartoon short created by Walt Disney in 1948. It was nominated for Academy Award for Best Animated Short Film, but lost to MGM's Tom and Jerry cartoon The Little Orphan, which shared one of seven Oscars for the Tom and Jerry series. It was the 122nd short in the Mickey Mouse film series to be released, and the second produced that year.

Lend a Paw is an animated short film produced in Technicolor by Walt Disney Productions, distributed by RKO Radio Pictures and released to theaters on October 3, 1941. Lend a Paw was directed by Clyde Geronimi and features original music by Leigh Harline. George Nicholas, Kenneth Muse, Nick Nichols, William Sturm, Eric Gurney, Norman Tate, Chick Otterstrom, Morey Reden, and Emery Hawkins animated the film. The voice cast includes Walt Disney as Mickey and Teddy Barr as Pluto. It was the 115th short in the Mickey Mouse film series to be released, and the sixth for that year.

In the cartoon, which was largely a remake of the 1933 short Mickey's Pal Pluto, Pluto saves the life of a kitten, and later feels jealous towards the kitten after Mickey Mouse takes the kitten in. The film won the Academy Award for Best Animated Short Film at the 14th Academy Awards in 1942, the only Mickey Mouse short to win the award.

How to Play Football is an animated comedy short film by Disney starring Goofy, released on September 15, 1944. The short was directed by Jack Kinney. The seven and a half minute film was nominated for an Academy Award for Best Animated Short Film, but lost to the Tom and Jerry cartoon Mouse Trouble by MGM.

Silly Symphony (also known as Silly Symphonies) is an American animated series of 75 musical short films produced by Walt Disney Productions from 1929 to 1939. As the series name implies, the Silly Symphonies were originally intended as whimsical accompaniments to pieces of music. As such, the films usually did not feature continuing characters, unlike the Mickey Mouse shorts produced by Disney at the same time (exceptions to this include Three Little Pigs, The Tortoise and the Hare, and Three Orphan Kittens, which all had sequels). The series is notable for its innovation with Technicolor and the multiplane motion picture camera, as well as its introduction of the character Donald Duck, who made his first appearance in the Silly Symphony cartoon The Wise Little Hen in 1934. Seven shorts won the Academy Award for Best Animated Short Film.

Many of the shorts were adapted into print mediums. Starting in 1932, a Silly Symphony newspaper comic strip was distributed by King Features Syndicate, as well as a Dell comic book series and numerous children's books.

Wilfred Emmons Jackson (January 24, 1906 – August 7, 1988) was an American animator, musical arranger and director best known for his work with Walt Disney Productions.

Jackson joined Walt Disney Productions in 1928 as a volunteer washing animation cels. He was soon promoted to an animator and was instrumental in developing the Mickey Mousing technique, which synchronized the music and action for Steamboat Willie (1928). He was then made the director for the Mickey Mouse and Silly Symphonies cartoon series, of which he directed the Academy Award-winning short films: The Tortoise and the Hare (1935), The Country Cousin (1936), and The Old Mill (1937). His feature film directorial debut was Snow White and the Seven Dwarfs (1937).
