Church sex abuse exposé creates Oscar buzz

Alex Gibney, an award-winning documentary maker whose work has focussed on Lance Armstrong, Julian Assange, and Enron, has found his most contentious topic yet.

His Oscar-touted exposé, Mea Maxima Culpa: Silence in the House of God, traces a sex-abuse scandal from a Milwaukee Catholic church to the Vatican.

Gibney also shot parts of the film in Ireland and Italy and received €50,000 from the Irish Film Board. The movie was banned by the Venice and Rome film festivals this year.
