Martin McDonagh has this weird, prickly way of writing. If you've seen In Bruges or The Banshees of Inisherin, you know the vibe. It’s dark. It’s funny in a way that makes you feel a little guilty for laughing. But when he put together the cast of Three Billboards Outside Ebbing, Missouri, he hit a specific kind of lightning in a bottle. Most movies are lucky to get one performance that defines a career. This one got three.
Honestly, the movie shouldn't have worked as well as it did. The plot is miserable. A mother, Mildred Hayes, is grieving her daughter’s horrific murder and decides to shame the local police department by renting three massive, rusting billboards. It sounds like a standard procedural or a heavy-handed social drama. Instead, it’s a character study where nobody is purely a hero and almost everyone is a bit of a jerk.
Frances McDormand as the Unstoppable Mildred Hayes
Frances McDormand didn't just play Mildred; she sort of became a force of nature. It’s hard to imagine anyone else in that bandana. Before this, people knew her from Fargo, but Mildred is the polar opposite of Marge Gunderson. She’s jagged. She’s mean because she has to be.
McDormand actually hesitated to take the role. She was worried she was too old for the character’s backstory. McDonagh had to convince her, and thank God he did. Her performance is built on silences. You see it when she’s flipping over a beetle on its back while waiting for a phone call, or the way she stares down Woody Harrelson’s character with a look that could melt lead. She won the Academy Award for Best Actress for this, and it wasn't even a close race. She brings a blue-collar grit that feels authentic because she doesn't try to make Mildred likable. She just makes her real.
Woody Harrelson and the Moral Compass of Bill Willoughby
Woody Harrelson plays Chief Bill Willoughby. In any other movie, the police chief is the antagonist. He’s the guy blocking the protagonist's path. But McDonagh writes Willoughby as a decent man facing an impossible situation—both professionally and personally.
Harrelson has this laid-back, Southern charm that he can weaponize or use to break your heart. In this film, it’s the latter. His scenes with McDormand are some of the best in modern cinema because they aren't "movie" arguments. They’re two tired people who actually respect each other but are trapped on opposite sides of a fence. Willoughby is dying of cancer, a plot point that adds a ticking clock to the whole narrative. It’s a nuanced performance that earned him an Oscar nomination, and it serves as the emotional anchor that keeps the movie from spiraling into pure cynicism.
Sam Rockwell’s Controversial Redemption
If you want to talk about the cast of Three Billboards Outside Ebbing, Missouri, you have to talk about Sam Rockwell as Officer Jason Dixon. This is the role that sparked a thousand think-pieces. Dixon is, to put it bluntly, a racist, violent, "momma’s boy" cop with a badge and a chip on his shoulder.
Rockwell is a master of playing lovable losers, but Dixon isn't lovable at the start. He’s pathetic. The way Rockwell moves—sort of swaggering while looking like he’s about to trip—tells you everything about the character’s insecurity. When he won the Oscar for Best Supporting Actor, there was a lot of debate. Critics wondered if the movie was "forgiving" a character who had done unforgivable things.
But that’s the point of the performance. Rockwell doesn't play Dixon as a man who suddenly becomes "good." He plays him as a man who finally decides to try. It’s a messy, uncomfortable arc. He doesn't get a hero's ending; he gets a chance at some version of dignity.
The Supporting Players You Forgot Were There
The bench strength of this cast is ridiculous. You have Peter Dinklage playing James, the "town dwarf" who just wants a date and ends up being the only person who calls Mildred out on her hypocrisy. Then there’s John Hawkes as Mildred’s abusive ex-husband, Charlie. Hawkes is terrifying because he plays the character with a quiet, simmering threat rather than over-the-top villainy.
- Lucas Hedges: Plays Robbie, Mildred’s son. He’s the overlooked victim in all of this, trying to survive his mother’s grief. Hedges has this incredible ability to look like he's carrying the weight of the world on his shoulders.
- Caleb Landry Jones: As Red Welby, the guy who rents out the billboards. He gets thrown out of a window (literally) and still manages to show a moment of profound grace later in the film.
- Abbie Cornish: Plays Willoughby's wife, Anne. She provides the domestic warmth that makes Willoughby’s eventual fate feel so much heavier.
- Samara Weaving: She has a small, almost comedic role as Charlie’s nineteen-year-old girlfriend, Penelope. She’s the "comic relief," but even she gets a moment of weirdly profound insight about animals and reincarnation.
Why the Chemistry Matters
Usually, when you have this many big names, they compete for airtime. Here, they're all serving the script. McDonagh wrote the roles specifically for McDormand and Rockwell. You can tell. The dialogue fits them like a glove.
The movie was filmed in Sylva, North Carolina, and that location plays a huge part too. The town feels lived-in. When the cast interacts with the environment—the gift shop, the police station across the street from the advertising office—it doesn't feel like a set. It feels like a small town where everyone knows everyone’s business and nobody's forgotten anything that happened twenty years ago.
The Legacy of the Performances
Looking back, the cast of Three Billboards Outside Ebbing, Missouri changed how we think about "likable" characters. We’re so used to being spoon-fed protagonists we can root for without reservation. Mildred Hayes is hard to root for. Jason Dixon is even harder.

But the actors make them human. They show that grief makes people ugly. It makes them lash out. It makes them burn things down. By the time the credits roll, Mildred and Dixon are sitting in a car together, heading toward a destination they aren't even sure about. They haven't "solved" anything, and they haven't fixed themselves. They’re just... moving.
Taking the Next Steps
If you’re looking to dive deeper into the work of this specific group of actors or the style of this film, here are a few things you should actually do:
- Watch "The Banshees of Inisherin": If the tone of Three Billboards clicked for you, this is McDonagh’s follow-up. It features a similarly tight-knit cast dealing with isolation and shifting friendships, though it’s set in 1920s Ireland.
- Explore Frances McDormand’s "Nomadland": To see the evolution of her "tough woman on the fringes" archetype, this film (which won her another Oscar) is the natural progression from Mildred Hayes.
- Research the "Three Billboards" Effect: After the movie came out, real-life activists started using the three-billboard format for protests everywhere from London to Miami. It’s a rare instance of a movie's visual language jumping directly into real-world political activism.
- Track Sam Rockwell’s Character Work: Watch Confessions of a Dangerous Mind or Moon to see how he builds these high-energy, slightly off-kilter characters that eventually led to his nuanced work as Jason Dixon.
The film remains a masterclass in ensemble acting. It isn't always comfortable to watch, and it shouldn't be. It’s a messy story told by actors who weren't afraid to look bad, and that’s exactly why it’s still being talked about years later.
