20 years after Calvin and Hobbes stopped appearing in daily newspapers, filmmaker Joel Allen Schroeder has set out to explore the reasons behind the comic strip's loyal and devoted following.

Dear Mr. Watterson

A documentary on comic strips, with never-seen-before interviews from Bill Watterson (Calvin & Hobbes), Jim Davis (Garfield), Jeff Keane (Family Circus), Cathy Guisewite (Cathy) and dozens more. The film asks a central question: Where do comic strips go when newspapers die? Everybody loves comics, but will they survive in a digital world?
