I figured I'd bump this thread with some information!
This film will be released in 2012 and will be called "The Master"
Here is the summary from Wikipedia.
A charismatic intellectual (Hoffman) launches a faith-based organization following World War II. A drifter (Phoenix) becomes his right-hand man but as the faith begins to gain a fervent following, the drifter finds himself questioning the belief system and his mentor.
Here is the cast
Philip Seymour Hoffman as Lancaster Dodd
Joaquin Phoenix as Freddie Sutton
Amy Adams as Mary Sue Dodd
Laura Dern as Helen
Ambyr Childers as Elizabeth, Lancaster's daughter
Jesse Plemons as Val Dodd, Lancaster's son
Lena Endre as Mrs. Solstad
Rami Malek as Clark, son-in-law of Lancaster Dodd
Madisen Beaty as Doris Solstad
Joshua Close as Wayne
W. Earl Brown as Bus
David Warshofsky as a detective
Kevin J. O'Connor as Bill White
Well now........ Paul Thomas Anderson directed my favorite film of all time and this movie sounds absolutely incredible. Hoffman and Phoenix are two of the best actors alive (yes, I thought Phoenix's rap-hoax turned mockumentary was a work of genius and truly showed how amazingly talented he is). I am beyond pumped for this film.
Clearly this film is going to be very critical of Scientology, although it will do so indirectly. After There Will Be Blood it is quite obvious that Paul Thomas Anderson is not a fan of organized religion.
