Do all dogs go to heaven? Two documentary filmmakers explore mortality and mourning through the experiences of pet owners. In PICKLE, Amy Nicholson profiles a couple of extreme animal lovers, interviewing them about the menagerie they’ve cared for and buried over the years, including paraplegic possums, emaciated cats, and morbidly obese chickens. Errol Morris’s debut feature, GATES OF HEAVEN, immerses viewers in the community surrounding two pet cemeteries in Napa Valley, California, blending sincerity and satire to spin its quirky subject into a surprisingly expansive study of human nature.
