The film originally started as a comic.

Storyboards and visual development took a year.
Another year for animation.

Animation is on twos because it looks better.
Most of it is rendered in camera with very little compositing.

Characters, environments, rigging, animation, rendering all in Maya.
A few random things in After Effects, then assembled in Premiere.
Oh, and Photoshop. Always Photoshop.

Plus Chick Webb on the playlist while animating.

Here’s some more images to give a glimpse into how it was made.
A lot are work-in-progress, not all of the ideas made it into the final film.
