Alex Gibney sets sights on church cover-up in 'Mea'

The prolific Alex Gibney ("Taxi to the Dark Side") has tackled torture, corruption and insider politics in some of the most indelible documentaries of recent years.

In his latest, "Mea Maxima Culpa: Silence in the House of God," the filmmaker takes on sexual abuse in the Catholic Church.

His movie depicts the horrific story of Father Lawrence Murphy, a priest who abused some 200 children when he led the St. John School for the Deaf in Wisconsin from 1950 to 1974.

With the film centered on testimony from four of Murphy's victims, Gibney unpacks a cover-up that extended to the highest echelons of the Church.

amNewYork spoke with Gibney about the movie, which airs Monday night on HBO.
