William H. Macy in Exorcism-on-a-Train Movie 'Speed Demon' Trailer

by Alex Billington **April 21, 2026

_ "I'm going to save every soul on this train."_ Maverick Films + Complex Corp unveiled the official trailer for a bonkers B-movie horror called Speed Demon**, an exorcism-on-a-train flick from filmmaker Jon Keeyes. Alas this is not a horror comedy despite the premise being perfect for a horror comedy spoof riff (instead watch: Stop! That! Train!). And if you don't read the synopsis close enough, you might get excited thinking this is about a possessed train that gets an exorcism while it's on the tracks. Alas it's just about a deranged passenger. Aboard a high-speed train from Montreal to New York City, a Nun who is losing her faith must perform her first Exorcism on a possessed passenger hellbent on crashing the runaway train. Starring Katie Cassidy and William H. Macy as Sister Lu and Father Novak. This actually looks pretty solid for a junky VOD horror movie, especially with such a ridiculous concept. I just still wish the train itself was possessed...

Here's the official trailer (+ poster) for Jon Keeyes' horror film Speed Demon, direct from YouTube:

When Father Novak (William H. Macy) and Sister Lu (Katie Cassidy) 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._ Speed Demon is directed by B-movie genre filmmaker Jon Keeyes, director of the films Living & Dying, Fall Down Dead, Doom Room, Phobia, The Harrowing, Rescue Hostage, The Survivalist, Cult Killer, Code Name Banshee, The Clean Up Crew previously. The screenplay is written by Domenico Salvaggio. Produced by Katie Cassidy, Cecil Chambers, Vanessa Coifman. Maverick Film releases Jon Keeyes' Speed Demon film in select US theaters + on VOD starting on May 31st, 2026 coming up soon. Anyone want to watch this?
