This is an interesting film about SUNDS, Sudden Unexplained Death Syndrome. A Baton Rogue (or there about) night time talk show host, Charlie Crow (Dallas Roberts) has a call-in guest who dies from SUNDS having predicted his death on air. He blames the "Shadow People" who come for him. Alison Eastwood (Clint's daughter) is called in from the CDC to investigate.
The film incorporates "actual footage" of the real host "Charlie Camfield" and various news feeds. The people in these "actual films" are different than the actors portraying them in order to give the film a sense of realism. I believe they are uncredited actors as the film also includes police interrogation films as well as people/news casters who do not exist in the world of Google.
Dallas Roberts did a good job, but the script was bland. Your villain is "shadow people" who only come if you imagine them. This is not a documentary about the syndrome. The scare factor doesn't exist... until you go to sleep. A well done interesting film that goes nowhere.
Actual studies are interesting as it appears people suffer heart fibrillation while sleeping. Younger males are most susceptible with epilepsy, stress (from relocation) and perhaps diet prior to bedtime (carbs) being linked as contributing factors.
