Brent Lang Executive Editor David Cronenberg is returning to Cannes with “The Shrouds,” the story of an industrialist named Karsh, who invents a controversial technology that allows grieving families to see inside the graves of their loved ones with high-resolution cameras. It’s a film that defies easy categorization. This being a Cronenberg production, there are elements of body horror, but there’s also a conspiracist undercurrent, as Karsh (Vincent Cassel) begins to suspect that shadowy forces are undercutting his expansion plans after his cemetery is ransacked.
