The drama that deals with the history of accusations of sexual abuse by priests that came to light in 2002, plaguing the Catholic Church. Dan Curtis is set to direct the film, with a screenplay penned by Thomas Michael Donnelly, slated to begin filming in June.

"The film will depict the interwoven cross-section of priests, victims, lawyers and newspaper reporters who have been caught up in this story since it first broke two years ago," states a Showtime release.

The trade paper said that Dennehy will play Boston priest Father Domenic Spagnolia, a well-known straight shooter who criticizes the archdiocese then finds himself wrapped up in turmoil when an ex-lover outs him. Plummer was previously announced as the controversial Boston Cardinal Law who was at the center of the scandal.

Dennehy won a 2003 Tony Award for his performance in Long Day's Journey Into Night. His other Broadway appearances include Translations and another Tony-winning turn in Death of a Salesman. He also recently played the title role in Trumbo Off-Broadway.

Plummer, known for his role as Captain Von Trapp in the film version of The Sound of Music, appeared on Broadway this season in King Lear. His other Broadway credits include J.B., Othello, No Man's Land, Cyrano and Barrymore — winning Tony Awards for his performances in the latter two.
