Maverick Film and Complex Corp have released a new trailer for Speed Demon, a horror thriller starring William H. Macy (Shameless) and Katie Cassidy (Arrow). Check out the trailer above!

Speed Demon

The official synopsis reads: “When Father Novak and Sister Lu board a train from Montreal to New York City, they weren’t prepared for the danger and evil that would pursue them. After the train is taken over by the demon Asmodeus, Father Novak and Sister Lu must battle possessed passengers on a runaway train with Sister Lu forced to overcome her faltering faith and perform the first exorcism done by a nun.

Jon Keeyes (Cult Killer) directs from a script by Domenico Salvaggio (Die). “Speed Demon is an intensely fun horror movie. It’s got a strong story, demons, action, plenty of special effects, and truly unique characters,” said Keeyes in a statement. “Getting to work with Katie Cassidy and William H. Macy was a complete joy. Bill was incredible as our Father Novak, and such a professional, bringing a real heart to the character. And Katie nailed it as a nun who has lost her faith, struggles with addictions, and must overcome her past in order to become this kickass warrior nun.

Speed Demon will be released in select theaters, On Demand, and on Digital on May 31.

William H. Macy

Macy had quite the year, appearing in Train Dreams, Soul on Fire, The Running Man, and Frontier Crucible in 2025.

He’s got a couple of projects coming up, including Brian, a coming-of-age comedy starring Ben Wang (Karate Kid: Legends). In an attempt to get closer to his teacher, Brian launches a high-stakes campaign running for school president that sparks a messy, exquisitely awkward journey toward self-acceptance. The film debuted at SXSW last month, but doesn’t have an official release yet.

There’s also The Land, an upcoming drama series created and written by Dan Fogelman. The series is set in the world of the NFL and features a generational family element. In addition to Macy, the series also stars Christopher Meloni, Mandy Moore, Chloe Bennet, Chace Crawford, Bridget Moynahan, Benjamin Bratt, Omar Epps, and more.
