Hillbilly Hare 1

The opening scene, with Bugs walking through the woods and singing "I Like Mountain Music," is animated by Emery Hawkins, who gives us a skinnier, more fluidly-animated Bugs than the other animators.

After the first hillbilly sticks a gun in Bugs's face, Charles McKimson takes over. Charles McKimson was given a lot of the close-ups and "characterization" moments in Bob's cartoons; his animation of Bugs seem to stick the closest to Bob's pose drawings, and reflect some of Bob's own preferences as a director, like giving Bugs heavy eyelids and a kind of wise-ass Groucho Marx attitude.
