MILWAUKEE---Local movie goers flocked to the Oriental Theatre Friday night to see a documentary marking one of the darkest times in the history of the Milwaukee Catholic Church.

"Mea Maxima Culpa" tells the story, many times in sign language from the victims of a notorious pedophile priest.

Lawrence Murphy molested 200 children at the former St. John's School for the Deaf.

Academy Award winner Alex Gibney even convinced the controversial former archbishop, Rembert Weakland, to participate in the film which documents a cover up.

"I was raised Catholic and this is a subject that has a lot of emotional power for me," Gibney told CBS 58 News.

"The reason this story was so powerful was twofold. One, it's a local story that goes all the way to the top of the Catholic Church. Two, at the heart of this story is a group of heroes, deaf men who were determined that their voices were heard."

The Archdiocese issued a statement which read in part:

"The Catholic Church has taken significant steps to purge this abuse from our communities, even society at large. Each time these terrible events are recounted it is like picking a scab off an old wound. It hurts everyone, especially those who suffered abuse and their families."
