 Funny, inspiring, and bizarre, "Gates of Heaven" is the celebrated pet cemeteries documentary that is in reality an unorthodox look at life. Inspired by an article entitled "450 Dead Pets Going to Napa Valley," Errol Morris set out to capture the event which centered around the transport of hundreds of animal remains from one pet cemetery to another. Pet cemetery proprietors, embalmers, pet owners and others speak about life, work, and feelings.
