In 1933, during the Great Depression, Hannah dropped off his portfolio at Walt Disney Studios, and soon afterward was hired as an in-between and clean-up artist, working on Mickey Mouse, Donald Duck, and Silly Symphony cartoons.
After thirteen films in that capacity, he was assigned to the story department writing cartoon short continuities, beginning with Donald's Nephews (released on April 15, 1938).
Hannah in subsequent years did a handful of other Donald Duck comic book stories[3] but, unlike Barks, he stayed at the studio and eventually was given a chance to be a director.
Hannah hoped to segue into a career in live-action but "Walt had me pegged as an animation director so he balked at the suggestion.
Besides directing shorts, Hannah also was assistant director for the television series The Woody Woodpecker Show, which began airing on October 3, 1957.
The most famous of these antagonists are Chip 'n Dale, but other characters included Spike the Bee, Bootle Beetle and a colony of ants.
