One of the funniest and most bizarrely touching documentaries ever filmed, "Gates of Heaven," Errol Morris' tribute to "puppy love," looks at the operators and customers of California pet cemeteries, interviewing folks whose concern for their dogs, cats, birds, and other creatures is truly eternal. Then, Morris journeys to the sleepy Southern hamlet of "Vernon, Florida," where he chats with such resident eccentrics as a dedicated turkey hunter, a verbose preacher, and a lackadaisical hunter for a memorable slice of oddball Americana. 137 min. total. Standard/Widescreen; Soundtrack: English Dolby Digital mono; bonus short "Werner Herzog Eats His Shoe" (1980); featurettes. Two-disc set.
