Let’s be honest. Seth Rogen and Evan Goldberg taking on Garth Ennis’s legendary, ultra-violent, and borderline blasphemous comic book felt like a recipe for a disaster. Fans were worried. How do you find someone to play a chain-smoking Texas preacher with the literal power of God? How do you cast a 100-year-old Irish vampire who is more interested in drugs than blood? Somehow, they nailed it. The cast of The Preacher didn't just play these roles; they lived in them for four seasons of absolute, unadulterated chaos on AMC.
If you go back to 2016, the landscape of "superhero" TV was mostly clean-cut. Then came Jesse Custer.

Dominic Cooper and the Weight of Jesse Custer
Dominic Cooper had a massive task. Jesse Custer is a man of few words and a whole lot of internal baggage. Cooper, known for Mamma Mia! and playing a young Howard Stark in the MCU, had to pivot hard. He traded the glitz for a dingy collar and a heavy Southern drawl that some critics argued felt a bit forced at first. But watch him again. By the time we get to the middle of season one, you realize the stiffness is intentional. Jesse is a man trying to repress a very violent nature.
He’s the anchor. Without Cooper's ability to look genuinely tormented while also being a complete badass in a bar fight, the show would have drifted into pure parody. He brought a certain "Old West" stoicism that balanced out the insanity happening around him. It’s that contrast. You have the Word of God coming out of his mouth—a voice that can literally make a man cut his own heart out—and yet Jesse remains profoundly human and deeply flawed.
The Unstoppable Force That Is Ruth Negga
Then there’s Tulip O'Hare. In the comics, Tulip was a blonde-haired, blue-eyed sharpshooter. When Ruth Negga was cast, some corners of the internet did what they always do—they complained. They were wrong. Negga’s performance is arguably the best thing in the entire series. She didn't just play a "tough girl." She played a woman who could build a bazooka out of tin cans and moonshine while talking about her feelings.
She has this energy. It’s frantic but focused. Negga was nominated for an Oscar for Loving right around the same time she was kicking ass on Preacher, and that range shows. She gave Tulip a vulnerability that made her relationship with Jesse feel like more than just "exes with guns." It felt like two soulmates who were probably going to kill each other eventually. Honestly, the chemistry between her and Cooper—who were a real-life couple for a long time—was palpable. It wasn't just acting; it was history.
Joseph Gilgun: The Only Cassidy Possible
You cannot talk about the cast of The Preacher without mentioning Joseph Gilgun. If you’ve seen Misfits or This Is England, you knew he was capable of playing a lovable scumbag. But Proinsias Cassidy is a different beast entirely. Cassidy is a vampire who hates vampires. He’s a walking disaster area.

Gilgun brought a frantic, spindly, wide-eyed mania to the role. He didn't use prosthetics to look scary; he used his own jagged energy. Most of the show's heart—and most of its humor—sits squarely on his shoulders. Whether he's ranting about why The Big Lebowski is overrated or trying to hide his undying love for his best friend's girlfriend, Gilgun makes you care about a guy who is objectively a monster.
It's the little things. The way he slumps on a sofa. The way he looks at Jesse with a mix of awe and resentment. It’s a masterclass in character acting.
Supporting Players and the Villains We Loved to Hate
The show excelled at casting the weirdos. Let's look at Herr Starr, played by Pip Torrens. Starr is the leader of The Grail, a secret organization protecting the bloodline of Jesus. Torrens played him with a deadpan, bureaucratic coldness that made the character’s descent into physical humiliation (loss of hair, loss of... other things) even funnier. He was the perfect foil to the messy, emotional main trio.
- Jackie Earle Haley as Odin Quincannon: Only an actor of Haley’s caliber could make a man obsessed with meat seem genuinely terrifying. He brought a grounded, gritty horror to the first season that set the stakes.
- Ian Colletti as Arseface (Eugene): Talk about a difficult role. Colletti spent hours in heavy prosthetics that made his face look like... well, the name says it all. Yet, he managed to emote through all that rubber, creating a character that was the moral compass of a show that didn't have a North Star.
- Graham McTavish as The Saint of Killers: The man is a mountain of granite. McTavish didn't need many lines. He just needed to walk into a room and make the audience feel like death had arrived. His presence was a constant, looming threat that kept the plot moving forward.
Why This Specific Chemistry Worked
Most shows struggle with the "trio" dynamic. Usually, one person feels like a third wheel. In Preacher, the dynamic between Jesse, Tulip, and Cassidy was a rotating triangle of loyalty and betrayal. They were all broken people trying to find a version of God that actually cared about them.
The casting directors, Libby Goldstein and Junie Lowry-Johnson, looked for actors who could handle the tonal whiplash. One minute, it’s a slapstick fight scene involving a chainsaw in a church; the next, it’s a quiet moment about the trauma of childhood abuse. Not every actor can do both. This crew could.
The Misconception of "Comics vs. Screen"
People often get hung up on physical descriptions. "He doesn't look like the drawing!" is the common cry. The cast of The Preacher proved that essence matters more than eyebrows. Dominic Cooper might not be as hulking as the comic book Jesse, but he captured the "I'm going to do the right thing even if it kills everyone" attitude perfectly. Ruth Negga isn't the comic's Tulip, but she is the definitive Tulip.
The Production Reality
Filming this show wasn't easy. Season one was shot in New Mexico, standing in for Annville, Texas. The heat was real. The grit was real. By season two, they moved to New Orleans, and you can feel that swampy, humid atmosphere bleeding into the performances. The cast had to adapt to different locations and a shifting narrative focus every single year.
It's also worth noting the smaller roles. Betty Buckley as Gran'ma Marie L'Angelle in season three was a stroke of genius. She brought a terrifying, grandmotherly malice to the screen that was far more effective than any CGI monster. Noah Taylor as Adolf Hitler—yes, that was a real plot point—played the role with a pathetic, manipulative whimpering that was both hilarious and deeply uncomfortable.
What to Watch Next If You Miss the Crew
If you've finished the series and you're feeling a void, you should follow the actors.
- Ruth Negga: Check out Passing on Netflix. It's a complete 180 from Tulip O'Hare and shows her incredible range.
- Joseph Gilgun: Watch Brassic. He co-created it, and it carries much of that same chaotic, working-class energy he brought to Cassidy.
- Dominic Cooper: Go back to The Devil's Double, where he plays two completely different characters. It proves he’s always had that "suppressed violence" thing down pat.
The legacy of the cast of The Preacher is that they took a "unfilmable" book and made it a cult classic. They didn't play it safe. They leaned into the weirdness, the blood, and the dark humor.

To really appreciate the work put in, re-watch the "Fight in the Plane" sequence from the pilot or the "Hotel Hallway Fight" with the angels. Look at the choreography, but more importantly, look at the facial expressions. These actors were having the time of their lives, and it shows in every frame.
The best way to experience the brilliance of this ensemble is to start from the beginning and pay attention to how they change. Jesse grows more arrogant, Tulip grows more desperate, and Cassidy grows more weary. It's a character study wrapped in a blood-soaked road trip. Don't just watch for the action; watch for the moments where they aren't saying anything at all. That’s where the real magic of this cast lives.
