From commanding 51 to commanding the Wild West, Mulroney leads a star-studded cast in a tale of revenge, redemption, and survival.
Dermot Mulroney, who turned heads this season as the enigmatic Chief Pascal on Chicago Fire, is blazing a new trail — this time through the lawless desert plains of the 1880s Arizona Territory in the upcoming western thriller, Long Shadows.
ScreenRant has the exclusive first look at the trailer, and it’s packed with everything you wouldn’t expect from the Chicago Fire alum: six-shooters, outlaw codes, and a dark emotional journey that swaps firehouse drama for frontier danger.
🔥 From Firehouse 51 to Frontier Guns
Mulroney stars as Dallas Garrett, a reformed outlaw with a haunted past who takes a young man under his wing in a world where trust is scarce and survival means everything. He’s joined by a standout cast including:
-
Blaine Maye as Marcus Dollar, an orphan seeking revenge for his murdered parents
-
Jacqueline Bisset as Vivian Villeré, a mysterious madam with a dangerous grip on her saloon
-
Dominic Monaghan as Ned Duxbury, her unpredictable associate
-
Sarah Cortez as Dulce Flores, a gifted pianist caught in a web of exploitation
-
Grainger Hines as Sheriff Wesley Tibbs, a lawman running from his own ghosts
🎯 A Gritty Story of Loss and Redemption
Long Shadows begins when Marcus is released from an orphanage at 18 and sets off to track down the horse thieves who killed his parents. Along the way, he crosses paths with Garrett, who becomes a mentor, teaching him how to shoot — and more importantly, how to live with the choices that follow.
“He brought restrained gravitas and moral weight to Dallas Garrett,” says director William Shockley of Mulroney. “He’s a man who’s made mistakes and is trying to guide someone away from repeating them.”
🎬 Western With a Heart — and a Punch
The trailer teases a moody, emotional western with intense gunfights, dusty landscapes, and stolen moments of tenderness. But at its core, Long Shadows is about the weight of grief, the lure of vengeance, and the redemptive power of connection.
Director William Shockley, best known for his work on Dr. Quinn, Medicine Woman, makes his debut behind the camera and calls this story “an emotional, engaging period piece rooted in faith and humanity.”
💫 Mulroney Shines in a Bold New Role
Fresh off his commanding turn on Chicago Fire, Mulroney disappears into the role of Dallas Garrett — a gunslinger with a blind eye (literally, thanks to a prosthetic) and a heavy conscience.
He’s not saving firefighters anymore — he’s saving a boy from becoming the worst version of himself. It’s a gritty, grounded performance that may surprise longtime fans of Chief Pascal.
🗓️ In Theaters This Fall
Long Shadows will hit theaters September 26, distributed by Quiver Distribution. With its star power, striking visuals, and a story soaked in sorrow and second chances, it’s one fall film that promises to leave a lasting mark — especially for fans of Chicago Fire eager to see Mulroney in a completely new light.
