The trailer for the upcoming Fox series “The Exorcist” is online and damn if it’s not compelling. Based on William Blatty’s classic 1971 novel, the show follows a small parish priest and a modern day Templar Knight as they fatefully join forces to fight an evil ripping apart a Chicago family as it grows stronger.

Alfonso Herrera (“Sense8”) plays the young parish priest and Ben Daniels (House of Cards) the Templar Knight. The tormented family are stunners Brianne Howey (“Scream Queens”) and Hannah Kasulka (“True Blood”), Alan Ruck (Ferris Bueller), and oh-shit-what-happened-to Geena Davis (Thelma & Louise).
