Outcast, Cinemax‘s exorcism drama from The Walking Dead executive producer Robert Kirkman and Chris Black, has added six new cast members as production begins in South Carolina. David Denman (13 Hours), Melinda McGraw (Mad Men), Grace Zabriskie (The Killing), Catherine Dent (The Shield), Lee Tergesen (The Americans) and Brent Spiner have been cast opposite Patrick Fugit and Philip Glenister in the 10-episode series based on the Skybound/Image comic title by Kirkman and artist Paul Azaceta.

Outcast follows Kyle Barnes (Fugit), a young man who has been plagued by possession since he was a child. Now an adult, he embarks on a journey to find answers but what he uncovers could mean the end of life on Earth as we know it. Denman will play Mark Holter in a recasting, taking over the role played by Kip Pardue in the pilot. Married to Kyle Barnes’ (Fugit) sister Megan, Mark is a husband and father first – but a by-the-book small town cop a close second. He loves his wife deeply, but his innate sense of justice is challenged by her loyalty to Kyle, whom Mark can’t forgive for his past transgressions. McGraw is Patricia MacCready, a single mother and devout member of Rome’s Light of God Baptist Church and a regular at Reverend Anderson’s church teas. Zabriskie plays Mildred, one of the old guard of parishioners at Anderson’s church. Full of spit and vinegar, Mildred lives alone and says what’s on her mind. Dent is Janet Anderson, the ex-wife of Reverend Anderson. Their marriage was shattered by Anderson’s obsession with battling the forces of darkness, but she still can’t help but feel affection and sympathy for the man she once loved, the father of the her child. Tergesen plays Blake Morrow, a former police officer on death row for murdering his partner’s wife.

David Alpert, Sharon Tal Yguado and Sue Naegle executive produce with Black and Kirkman. Fox International Studios (a unit of Fox International Channels) is the studio. Denman is repped by Berwick & Kovacik, UTA, and Schreck, Rose, Dapello & Adams.
