It is a slow burn. Most people think they're walking into a standard Western or a typical "Liam Neeson-style" revenge flick when they press play on Let Him Go. They aren't. Not even close. The movie, directed by Thomas Bezucha and based on Larry Watson’s novel, relies almost entirely on the heavy lifting of a specific group of actors who know how to play "quiet" before the screaming starts. Honestly, the let him go cast is the only reason this movie doesn't collapse into a predictable melodrama. Without the specific chemistry between the leads, the whole thing would just be a grim story about grief.
Instead, we get something that feels like a classic 1960s thriller wrapped in a 2020 production.
The Power Couple: Costner and Lane
Kevin Costner and Diane Lane are the heartbeat here. It's funny because they already played a married couple in Man of Steel, but that was all capes and CGI. Here, they are George and Margaret Blackledge. George is a retired sheriff. Margaret is... well, she's the engine. When their son dies in a tragic horse-riding accident and their daughter-in-law remarries a man who turns out to be abusive, Margaret doesn't ask George if they should go find their grandson. She just starts packing the station wagon.
Costner does that thing he does best. He says nothing. He stares at the horizon. He looks tired. It’s a performance of exhaustion. He knows that following his wife into the wilds of North Dakota to confront a dangerous family is probably going to end badly, but he goes anyway. You see it in his eyes—he isn't going for the kid; he's going because he can't let Margaret go alone.
Lane, on the other hand, is fierce. She’s the one driving the car, literally and metaphorically. There’s a specific scene where she realizes her grandson is being hit by his new stepfather, and the look of pure, cold calculation on her face is terrifying. She doesn't cry. She plans. It’s a masterclass in "grandma rage" that feels entirely grounded in reality.
Lesley Manville and the Weboy Clan
If the Blackledges are the light, the Weboys are the pitch-black darkness. This is where the let him go cast gets truly interesting. Lesley Manville plays Blanche Weboy, the matriarch of a clan of outlaws in North Dakota. If you only know Manville from her sophisticated roles in Phantom Thread or The Crown, this will give you whiplash.
Blanche is a nightmare in a housecoat.
She smokes like a chimney and treats a dinner party like a psychological interrogation. The scene where the Blackledges first meet the Weboys is one of the most uncomfortable sequences in modern cinema. It starts with a forced "Midwestern nice" and slowly, painfully devolves into a threat. Manville plays it with a terrifying high-pitched laugh and a total lack of empathy. She isn't a cartoon villain. She’s a woman who has carved out a kingdom in the middle of nowhere and will kill anyone who looks at her sideways.

Then you have Jeffrey Donovan as Bill Weboy. He’s the "civilized" one of the brothers, which actually makes him scarier. He’s the scout. He’s the one who finds you before the rest of the pack arrives. Donovan has this oily charm that makes your skin crawl. He’s the bridge between the Blackledges' world of law and order and the Weboys' world of brutal, isolated violence.
Kayli Carter and the Collateral Damage
Kayli Carter plays Lorna Blackledge, the young widow caught in the middle. Her performance is heartbreaking because she’s so clearly trapped. She isn't a hero. She’s a scared kid who made a bad choice because she was lonely and broke. When you watch her, you realize the stakes aren't just about a "rescue mission." It’s about the fact that she has been completely subsumed by this cult-like family.
Booboo Stewart also shows up as Peter Dragswolf, a young Indigenous man living on the fringes of the story. Some critics felt his character was a bit of a plot device, but Stewart brings a quiet dignity to the role. He provides a brief moment of respite for George and Margaret, a reminder that there is still kindness in the world, even if it’s hiding in the shadows of the badlands.
Why This Cast Works for This Specific Genre
Traditional Westerns usually have a clear hero and a clear villain. Let Him Go blurs those lines until they are gone. George isn't a "tough guy" anymore; he's an old man with a bad heart. Margaret isn't a "damsel"; she’s the one demanding the fight.
The chemistry between Lane and Costner is what makes the final act so painful. You've spent two hours watching them bicker over road maps and hotel rooms, so when the violence finally explodes, it feels personal. It’s not just a movie climax. It feels like your own grandparents are in danger.
The film was shot primarily in Alberta, Canada, standing in for Montana and North Dakota. The landscape is huge and empty, which mirrors the isolation the characters feel. But the actors don't get swallowed by the scenery. They dominate it.
Key Performances Breakdown:
- Kevin Costner (George): The stoic protector. This is arguably his best work since Dances with Wolves because he strips away the "movie star" ego.
- Diane Lane (Margaret): The relentless force. She carries the emotional weight of the entire film.
- Lesley Manville (Blanche): Pure, unadulterated menace. She creates one of the most memorable female villains in recent memory.
- Jeffrey Donovan (Bill): The snake in the grass. His performance is all about the subtext of what he isn't saying.
The Reality of the "Midwest Gothic"
Let Him Go falls into a subgenre called "Midwest Gothic." It’s characterized by isolation, family secrets, and a sense of impending doom. The let him go cast understands this perfectly. They don't play the scenes for "action." They play them for tension.

Think about the dinner scene again. There is no physical violence for most of that sequence. It’s just people sitting around a table eating pork chops. But the way Manville eyes Lane, and the way Costner keeps his hands flat on the table, tells you everything you need to know. It’s a standoff without guns.
Critics have often compared this film to Unforgiven or No Country for Old Men. While it might not have the philosophical depth of a Coen Brothers movie, it has a raw, emotional core that those films sometimes lack. It’s a movie about the lengths a family will go to for their own.
Even the smaller roles, like Adam Stafford as the local sheriff who is clearly in the Weboys' pocket, add to the feeling of claustrophobia. You realize that George and Margaret are truly alone. There is no 911 to call. There is no backup coming.
Technical Mastery Behind the Scenes
While the actors are front and center, we have to talk about the cinematography by Guy Lodge. He uses a lot of natural light, which makes the night scenes feel terrifyingly dark. When the Blackledges are driving through the North Dakota night, the darkness feels like a physical wall. This helps the cast because they don't have to "act" scared; the environment is genuinely oppressive.
Michael Giacchino’s score is also worth a mention. Usually, he’s doing massive superhero themes or Star Wars scores. Here, he’s much more restrained. It’s a lot of solo piano and mournful strings. It stays out of the way of the performances, allowing the dialogue—or the silence—to take center stage.
What Most People Miss
People often overlook the fact that this movie is a tragedy, not an action film. If you go in expecting Taken on a horse, you'll be disappointed. This is a story about the cost of pride.
Margaret’s refusal to give up her grandson is noble, but it's also dangerous. The film doesn't shy away from the fact that her choices lead to a lot of the bloodshed. Diane Lane plays that nuance brilliantly. You see the guilt flickering in her eyes even as she doubles down on her mission.

And then there's the ending.
Without spoiling too much, the ending is divisive. Some find it cathartic; others find it devastating. But regardless of how you feel about the plot, the acting in those final fifteen minutes is some of the most intense work of the decade. Costner and Lane sell the desperation of a couple who have reached the end of their rope.
Actionable Takeaways for Movie Buffs
If you’re planning to watch or re-watch Let Him Go, keep these things in mind to get the most out of the experience:
- Watch the Hands: Pay attention to how the characters use their hands. Costner is often fidgeting with something or keeping his hands hidden, while Manville uses hers to dominate the space around her.
- Listen to the Silence: This is a quiet movie. The moments where no one is speaking are often more important than the dialogue.
- The Power Dynamics: Notice how the seating arrangements in the Weboy house indicate who holds the real power. Hint: It’s not the men.
- Historical Context: Remember that this is set in the 1960s. The lack of cell phones and GPS isn't just a plot device; it's a fundamental part of why the characters are so vulnerable.
Basically, the film works because it respects its audience's intelligence. It doesn't over-explain the history between George and Margaret. It assumes you can see their decades of marriage in the way they look at each other. It doesn't give Blanche a "tragic backstory" to explain why she's evil. She just is.
If you want to see a masterclass in ensemble acting where every person on screen is working at the top of their game, this is it. The let him go cast turned a solid thriller into a haunting piece of cinema that stays with you long after the credits roll.
Next time you're scrolling through a streaming service and see Costner’s face on the thumbnail, don't expect a typical Western. Expect a gut-punch.
To dive deeper into this kind of storytelling, check out the original novel by Larry Watson. It provides even more internal monologue for George and Margaret, which adds another layer to what Lane and Costner achieved on screen. You can also look into Thomas Bezucha’s previous work, like The Family Stone, to see how he handles complex family dynamics, albeit in a much lighter setting. Watching those two films back-to-back is a wild experience in seeing how a director can flip the script on family loyalty.
The best way to appreciate the performances is to watch the film in a dark room with no distractions. Let the slow pace do its work. By the time the third act hits, you’ll be glad you paid attention to the small details.
