4 stars (PG-13)

Julian Schnabel (“Basquiat,” “Before Night Falls”) offers a harrowing adaptation of the memoir of Jean-Dominque Bauby, who suffered a stroke and awoke from a coma to discover that he was suffering from “locked-in syndrome.” Completely alert and aware, the only action he was capable of was blinking one eye. Over time, communication is established and, though possessed with a strong sense of lyricism and even an eye for comic moments, Schnabel makes sure you get a sense of the horrific experience. “The Diving Bell and the Butterfly” is devastating. Expect to be shaken. 114 minutes. DVD INFO: Includes a commentary track, featurettes and a Charlie Rose interview with Schnabel.
