It's not every day that a documentary turns up in a film festival's genre sidebar, but Jessica Chandler's Death Boom earned its place in Tribeca Festival's midnight-adjacent Escape From Tribeca program. Narrated and coproduced by Eli Roth, whose name has become synonymous with cinematic mutilation, the film is a thorough and frequently illuminating survey of the largely unregulated billion-dollar death-care industry, encompassing funerals, embalming, cremation, burials, and more.
