Procedure: Stealing routine hospital patients’ organs and selling the innards on the black market as the victim remains in a carbon monoxide-induced permanent sleep

Literature junkies know the late Michael Crichton as the prolific author behind such lauded novels as Jurassic Park, Congo, and Sphere; what’s not so universally recognized, however, is Crichton’s filmography amassed as a movie director. The writer-turned-filmmaker’s best feature is Coma, a taut, paranoid thriller about one of the least ethical hospitals in all of film.

Coma, also written by Crichton, concerns a Boston surgical resident who uncovers her place of employment’s illegal and evil secret: Patients who check in for common surgeries are left in a vegetative state after their oxygen is replaced by carbon monoxide, a maneuver necessary to cut out the unjustifiably comatose patient’s organs for black market sales.

The lifeless bodies don’t just lie in the hospital beds the whole time, though; they’re relocated to a separate facility where the bodies are suspended in mid-air thanks to electrical wires latched onto the person’s long bones. Makes you want to reconsider that penis enlargement surgery, doesn’t it?
