Early development

Donald Duck's first film appearance was in the 1934 cartoon The Wise Little Hen, which was part of the Silly Symphonies series of theatrical cartoon shorts. The film's given release date of June 9 is officially recognized by the Walt Disney Company as Donald's birthday, though historian J.B. Kaufman, consultant of The Walt Disney Family Museum, discovered in recent years that The Wise Little Hen was first shown on May 3, 1934, at the Carthay Circle Theater for a benefit program, while its official debut was on June 7 at the Radio City Music Hall. Donald's appearance in the cartoon, as created by animator Dick Lundy, is similar to his modern look – the feather and beak colors are the same, as are the blue sailor shirt and hat – but his features are more elongated, his body plumper, his feet smaller, and his sclerae white. Donald's personality is not developed either; in the short, he only fills the role of the unhelpful friend from the original story.

Burt Gillett brought Donald back in a 1934 Mickey Mouse cartoon, Orphans' Benefit. Donald is one of a number of characters who are giving performances in a benefit for Mickey's Orphans. Donald's act is to recite the poems Mary Had a Little Lamb and Little Boy Blue, but every time he tries, the mischievous orphans heckle him, leading the duck to fly into a squawking fit of anger. This explosive personality would remain with Donald for decades to come.

Donald continued to be a hit with audiences. The character began appearing regularly in most Mickey Mouse cartoons. Cartoons from this period, such as the cartoon The Band Concert (1935) – in which Donald repeatedly disrupts the Mickey Mouse Orchestra's rendition of The William Tell Overture by playing Turkey in the Straw – are regularly noted by critics as exemplary films and classics of animation. Animator Ben Sharpsteen also created the classic Mickey, Donald, and Goofy comedy in 1935, with the cartoon Mickey's Service Station.

In 1936, Donald was redesigned to be a bit fuller, rounder, and cuter, beginning with the cartoon Moving Day. He also began starring in solo cartoons, the first of which was Ben Sharpsteen's 1937 cartoon, Don Donald. This short also introduced a love interest of Donald's, Donna Duck, who evolved into Daisy Duck. Donald's nephews, Huey, Dewey and Louie, would make their first animated appearance a year later in the 1938 film, Donald's Nephews, directed by Jack King (they had been earlier introduced in the Donald Duck comic strip by Al Taliaferro, see below). By 1938, most polls showed that Donald was more popular than Mickey Mouse.
