Wilfred Jackson in the context of "Lady and the Tramp"

Snow White and the Seven Dwarfs is a 1937 American animated musical fantasy film produced by Walt Disney and released by RKO Radio Pictures, based on the 1812 German fairy tale "Snow White" by the Brothers Grimm. The film was supervised by David Hand and a team of five sequence directors: Perce Pearce, William Cottrell, Larry Morey, Wilfred Jackson, and Ben Sharpsteen. It is the first animated feature film produced in the United States and the first cel animated feature film.

Snow White premiered at the Carthay Circle Theatre in Los Angeles, California, on December 21, 1937, and went into general release in the United States on February 4, 1938. Despite initial doubts from the film industry, it was a critical and commercial success, with international earnings of more than $8 million during its initial release against a $1.5 million production cost, becoming the highest-grossing film of 1938, and briefly holding the record of the highest-grossing sound film of all time. It was also the highest-grossing animated film for 55 years. The popularity of the film has led to its being re-released theatrically many times, until its home video release in the 1990s. Adjusted for inflation, it is one of the top-ten performers at the North American box office and is still the highest-grossing animated film with an adjusted gross of $2,297,000,000. Worldwide, its inflation-adjusted earnings top the animation list. Snow White was nominated for Best Musical Score at the Academy Awards in 1938, and the next year, producer Walt Disney was awarded an honorary Oscar for the film. This award was unique, consisting of one normal-sized, plus seven miniature Oscar statuettes. They were presented to Disney by Shirley Temple.

Pinocchio is a 1940 American animated musical fantasy film loosely based on Carlo Collodi's 1883 novel The Adventures of Pinocchio, produced by Walt Disney and released by RKO Radio Pictures. The production was supervised by Ben Sharpsteen and Hamilton Luske, and the film's sequences were directed by Bill Roberts, Norman Ferguson, Jack Kinney, Wilfred Jackson and T. Hee.

With the voices of Cliff Edwards, Dickie Jones, Christian Rub, Walter Catlett, Charles Judels, Evelyn Venable, Frankie Darro, Mel Blanc and Clarence Nash the film follows a wooden puppet, Pinocchio, who is created by an old woodcarver, Geppetto, and brought to life by a blue fairy. Wishing to become a real boy, Pinocchio must prove himself to be "brave, truthful, and unselfish." Along his journey, Pinocchio encounters several characters representing the temptations and consequences of wrongdoing, as a cricket named Jiminy, who takes the role of Pinocchio's conscience, attempts to guide him in matters of right and wrong.

Cinderella is a 1950 American animated musical fantasy film produced by Walt Disney Productions and released by RKO Radio Pictures. Based on Charles Perrault's 1697 fairy tale, the film follows Cinderella, the daughter of a widowed aristocrat, who is forced to become a servant of her cruel stepmother and stepsisters, until Cinderella's fairy godmother grants her the chance to attend the royal ball and meet the prince. The production was supervised by Ben Sharpsteen, and was directed by Wilfred Jackson, Hamilton Luske, and Clyde Geronimi. It features the voices of Ilene Woods, Eleanor Audley, Verna Felton, Rhoda Williams, June Foray, James MacDonald, and Luis van Rooten.

During the early 1940s, Walt Disney Productions had suffered financially after losing connections to the European film markets due to the outbreak of World War II. Because of this, the studio endured commercial failures such as Pinocchio, Fantasia (both 1940) and Bambi (1942), all of which would later become more successful with several re-releases in theaters and on home video. By 1947, the studio was over $4 million in debt and was on the verge of bankruptcy. Walt Disney and his animators returned to feature film production in 1948 after producing a string of package films with the idea of adapting Charles Perrault's Cendrillon into an animated film.

Mickey's Revue is a 1932 Walt Disney cartoon, directed by Wilfred Jackson, which features Mickey Mouse, Minnie Mouse, Horace Horsecollar and Clarabelle Cow performing a song and dance show. The film was delivered to Columbia Pictures on May 12 and released on May 25, 1932. It was the 41st Mickey Mouse film, and the fifth of that year.

A yokel in the audience laughs uproariously at every act; the character would soon be known as Dippy Dawg, and would eventually become a major supporting character, Goofy. Pinto Colvig's memorable "witless laugh" could be heard in the previous Mickey Mouse cartoon, The Barnyard Olympics, but this is the first time the character can be seen on screen.
