The List of Adrian ­Messenger (blu-ray)

British army Colonel Anthony Gethryn (George C. Scott) is contacted by his old friend, Adrian Messenger (John Merivale), to investigate 11 men, whose names Messenger provides. After a plane carrying Messenger is blown up by a mysterious perpetrator, Gethryn determines that the men on the list had been prisoners of war in Burma during World War II--and that someone connected to a minor British aristocrat (Clive Brook) is methodically murdering each man on the list.
