Gravitas Ventures has debuted a new full-length trailer for Dear Mr. Watterson, the Kickstarter-funded documentary that explores the influence of cartoonist Bill Watterson and his beloved comic strip Calvin and Hobbes.

It's a six-year passion project by director Joel Allen Schroeder, who raised $25,000 in 2010 so he, producers Christopher Browne and Matt McUsic, and cinematographer Andrew P. Waruszewski could interview a slew of cartoonists, editors and fans, and then another $96,772 in 2012. Dear Mr. Watterson, which had its festival premiere in April at the Cleveland International Fan Festival, will debut Nov. 15 in theaters and On Demand.

“Mr. Watterson has inspired and influenced millions of people through Calvin & Hobbes,” the documentary’s website explains. “Newspaper readership and book sales can be tracked and recorded, but the human impact he has had and the value of his art are perhaps impossible to measure. This film is not a quest to find Bill Watterson, or to invade his privacy. It is an exploration to discover why his ‘simple’ comic strip made such an impact on so many readers in the 80s and 90s, and why it still means so much to us today.”
