Bill Watterson, the creator of the comic strip Calvin & Hobbes, is famously media-averse. He’s given two interviews, total since he retired his strip in 1995. Reporters have staked out his home in Ohio to no avail. The man just prefers not to be a public figure. But in the documentary Stripped (which you can buy or rent on iTunes), Watterson not only gives an interview, he drew the art for the poster—the first Watterson cartoon to be published in nearly 20 years.
