Ewan McGregor exchanges a light saber for a word processor, and Pierce Brosnan goes from reporting to "M" to being "P-M" in director Roman Polanski's political thriller The Ghost Writer, playing this week at Maiden Alley Cinema in Paducah. Brosnan plays Adam Lang, a former British Prime Minister accused of war crimes and McGregor is the writer hired to help him with his memoirs; it's a task that proves more perilous than he realizes. Todd Hatton and Larry Thomas look into The Ghost Writer.
