“Brave Little Tailor is a 1938 Disney cartoon featuring Mickey Mouse. Comparing story sketches by Jack Kinney to [the final] animation by Frank Thomas, we can clearly see how decisions about a character’s posture and emotional attitude made at the story stage continued into the animation.
“Here are some comparisons between story sketches and final frames. Animator Frank Thomas is a far better draftsman than Kinney. In each case, Thomas has refined the pose, making it more attractive. However, the content of each pose – what it says about Mickey’s thoughts and emotions – is the same as in Kinney’s cruder originals. Of course, Thomas adds movement, doing dozens of drawings for each one of Kinney’s, but while Thomas elaborates on Kinney’s work, Kinney’s decisions survive in Thomas’s animation.
