"You can call it a 'graphic novel,' but comic books are still incredibly stupid," sneered Calvin & Hobbes cartoonist Bill Watterson in one of his anthology introductions. Kim Deitch would beg to differ. The celebrated underground cartoonist and animator will be at the Castro Theatre to sign copies of his 12th graphic novel, The Amazing, Enlightening and Absolutely True Adventures of Katherine Whaley!, and it sounds pretty freaking smart to us. Set in turn-of-the-century New York, Katherine Whaley! is the story of a young girl's discovery by an eccentric aspiring filmmaker, Charles Varnay, and his remarkably intelligent talking dog, Rousseau. It's a tale of pseudo-Mormonism (Varnay hears Jesus speak through metal urns), magical realism, and movies. Deitch's timing is as impeccable as his illustrating — the book signing takes place in front of the Castro Theatre at 7 p.m., just in time to catch the 7:30 screening of Prix De Beauté, the first screening of the Silent Film Festival.
