I bought a copy of I Want My Hat Back (Jon Klassen, Candlewick Press, 2011) as a present for my niece. I enjoyed the book so much that I bought another copy and decided to do an animated short as a fun project for myself and my family. I copied the pages directly from the book and pieced them out in Photoshop, then created the mouths in Illustrator and animated the scenes in After Effects. I used voices of my family members for the characters and lip-synced them to the animals using dialog directly from the book.
The music is by Tosca Tango Orchestra.
