Beware all those who fall under the scrutiny of Alex Gibney. The documentary filmmaker first came to mass attention with his acclaimed documentary Enron: The Smartest Guys in the Room, a movie that from initially looking at the sudden bankruptcy of the American energy company provided a prescient examination into the greed and corruption that can occur inside modern financial institutions. This was followed by winning an academy award in 2007 for Taxi to the Dark Side, a film that took the death of an Aghan taxi driver at the Bagram Internment Facility to examine the ways the United States policy on torture defies the Geneva Convention. His new film Mea Maxima Culpa: Silence in the House of God goes straight for the Vatican jugular. The title translates roughly as 'My very great fault', and focuses on four men who as children were abused by a local priest in Milwaukee, USA. From their initial plight to get their stories heard the film expands to cover the recently revealed sex scandals across the world, and how in the Catholic Church these atrocities can be linked up the chain of command all the way to the Pope himself.
