Back in May, Fox issued a series order for their new horror series The Exorcist, based on the iconic 1973 thriller that many still think is the scariest movie of all time. The series will air in the Friday 9 PM time slot this fall, debuting on September 23, but for those heading to Comic-Con later this month, you'll get to see the first episode at its SDCC panel on Friday, July 22 at 6 PM ET in Room 6A. For those who won't be heading to San Diego in a few weeks, three new trailers have debuted with brand new footage.

These new teasers, which debuted on YouTube, reveal that Angela Rance's (Geena Davis) family is being haunted by a sadistic demon. This new series, described as a "propulsive psychological thriller," follows two very different priests tackling one family's case of horrifying demonic possession. Father Thomas Ortega (Alfonso Herrera) is the new face of the Catholic Church: progressive, ambitious and compassionate. He runs a small but loyal parish in the suburbs of Chicago. He has no idea that his quiet life is about to change forever.

Meanwhile, on the other side of the world, another priest finds himself locked in a life-and-death struggle with evil. Father Marcus Brennan (Ben Daniels,) is a modern-day Templar Knight, an orphan raised since childhood by The Vatican to wage war against its enemies. Father Marcus is everything Father Tomas is not: relentless, abrasive and utterly consumed by his sacred mission. Caught in the middle is the Rance family, members of Tomas' parish.

On the surface, they're a normal, suburban family, but all is not as it seems in this household. The patriarch, Henry Rance (Alan Ruck), is slowly but surely losing his mind. Eldest daughter Katherine (Brianne Howey) has become a recluse who refuses to leave her room. Her younger sister, Casey (Hannah Kasulka), thinks she's hearing strange noises coming from inside the walls. And mother Angela (Academy Award and Golden Globe winner Geena Davis) has been plagued by recurring nightmares, each more frightening than the last.

Angela believes there is something in the house, a demonic presence, growing stronger by the day. Desperate, she begs Father Tomas for help, unwittingly setting the naïve young priest on a collision course with Father Marcus. Separately, each faces an insurmountable task, but together they become the only hope against an evil force that has been mobilizing for centuries. Stay tuned for more from The Exorcist as the show gets ready to converge on Comic-Con later this month, and its series premiere this fall, but until then, check out these new trailers from The Exorcist.
