It appears that Robert Kirkman has finished the major casting on his pilot episode of Outcast, his new exorcism drama for Cinemax.  Just two weeks ago the casting of Patrick Fugit (Gone Girl) as chief protagonist Kyle Barnes and Phillip Glenister (Life on Mars) as the evangelical preacher Reverend Anderson was announced (see "'Outcast' Cast").
Today, according to The Hollywood Reporter, four more key roles were cast including that of Megan Holter, Kyle’s adoptive sister, a child psychologist, who will be played by Wrenn Schmidt.  Also joining the cast is Law and Order Criminal Intent’s Julia Crockett, who will play Kyle’s damaged and raving mother Sarah Barnes, as well as Kip Pardue (Ray Donovan), who will play Mark Holter, a skeptical cop and the husband of Kyle’s sister Megan, and Reg. E. Cathy (House of Cards), who will play Giles, the chief of police, who believes that there is some truth to stories of demonic possession.
Kirkman is writing the script for the Outcast pilot, the first time that he has written a pilot.  Cinemax bought the rights to Outcast before the first issue of the comic series was even published (see "Kirkman's 'Outcast' to Cinemax").  Given Kirkman’s track record the pilot should have a fairly good chance of being picked up, and given the immense bookselling success of Kirkman’s The Walking Dead, the Outcast project is clearly one that savvy retailers should keep under observation.
