Katie Cassidy (Arrow, A Nightmare on Elm Street 2010) stars as a rebellious nun who may be facing her last day on the job in more ways than one in the new trailer for Speed Demon.
The demonic horror movie releases in theaters, Digital, and on VOD on May 31, 2026.
In Speed Demon, “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.”
William H. Macy (The Running Man, Train Dreams) costars as Father Novak.
Watch the new Speed Demon trailer below, which introduces the hostile working relationship between Father and Sister when a vengeance demon takes control of their speeding train. Curiously, it’s a little girl who explains its purpose just before possession takes root.
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.”
Look for the horror movie next month.
