Gripping and important: “Kill the Messenger” (2014, 112 min) depicts a reporter’s suppressed attempts to cover the CIA involvement and secret support of large scale cocaine sales to fund the Nicaraguan Contras. The US feature film is based on the book of the same name by Nick Schou and the book Dark Alliance by Gary Webb. Not since 2003’s “Shattered Glass” has the journalistic pursuit of truth been presented on screen as such a mortally serious matter of honour.
