Brea Grant’s 12 Hour Shift is a weird one. It’s a blood-soaked, organ-harvesting dark comedy set in an Arkansas hospital in 1999. Honestly, if the movie didn't have such a specific, lived-in cast, the whole thing would have fallen apart under the weight of its own absurdity. You’ve probably seen some of these faces before, maybe on The Walking Dead or in classic horror staples, but here they’re playing roles that feel grimy, desperate, and weirdly human. It’s that grit that makes the cast of 12 hour shift stand out in a sea of polished, big-budget thrillers.
The Anchors: Angela Bettis and Chloe Farnworth
Angela Bettis is the heart of this movie, if you can call a cynical, drug-addicted nurse "the heart." She plays Mandy. Mandy is exhausted. She’s been on her feet forever, and she’s running a side hustle involving human organs. Bettis is a cult horror icon—you likely remember her from May (2002) or The Woman. She has this incredible ability to look like she’s about to vibrate out of her own skin while remaining completely deadpan.
Then you have Chloe Farnworth as Regina. Regina is the chaos agent.
While Mandy is calculating and tired, Regina is impulsive and, frankly, a bit of a mess. She loses a kidney—a literal human kidney—and the rest of the film is essentially a frantic scavenger hunt to replace it before some very scary people show up. Farnworth plays it with a frantic energy that should be annoying but ends up being hilarious because she’s so detached from the reality of the situation.
- Angela Bettis (Mandy): The weary professional criminal.
- Chloe Farnworth (Regina): The cousin who ruins everything.
- The dynamic: It’s a classic "straight man" vs. "wild card" pairing, just with more stabbings.
That Guy From Everything: Mick Foley and David Arquette
Wait, is that Mankind? Yeah. Mick Foley, the WWE Hall of Famer, shows up as Nicholas. It’s not a huge role, but seeing a wrestling legend in a scrub-filled hospital setting is jarring in the best way possible. He brings a physical presence that shifts the tone whenever he’s on screen.

Then there’s David Arquette.
Arquette also served as a producer on the film along with his wife, Christina Arquette. He plays Jefferson, a convict who is—unsurprisingly—causing problems. David has been leaning hard into the indie horror scene lately, especially after his return to the Scream franchise. In 12 Hour Shift, he’s less "Dewey Riley" and more "unhinged threat."
It’s interesting to see how Grant used these "names." They aren't just cameos meant to sell tickets. They actually fit into the weird, backwoods Arkansas ecosystem the movie builds.
The Supporting Players Who Actually Run the Hospital
The cast of 12 hour shift isn't just the leads. The background noise of the hospital is what makes the 1999 setting feel real.

Nikea Gamby-Turner plays Karen, and she is arguably the most relatable person in the entire building. She’s the coworker who just wants to get through the shift without everything exploding. Her chemistry with Bettis feels like two people who have worked together for twenty years and hate/love every second of it.
Kit Williamson (of EastSiders fame) pops up as Officer Myers. His character represents the utter incompetence of the local law enforcement, which is a recurring theme. The movie doesn't treat the police as a stabilizing force; they’re just another obstacle for Mandy to navigate.
- Nikea Gamby-Turner: The "done with this" energy.
- Kit Williamson: The oblivious lawman.
- Tara Doggett: Plays Dorothy, adding to the general sense of "why is this happening?"
Why the Casting Matters for Indie Horror
Most indie films struggle with tone. They either go too campy or too grim. Brea Grant avoided this by casting actors who understand "elevated genre." This isn't just a slasher. It’s a heist movie. It’s a comedy of errors.
If Mandy was played by someone less grounded than Angela Bettis, the organ harvesting plot would feel gross or unbelievable. Because Bettis looks like she hasn't slept since the Bush administration, you believe she’d sell a kidney just to make her life slightly less miserable.

The Arkansas Connection
The film was shot in Jonesboro, Arkansas. Most of the cast and crew stayed in a single hotel, which apparently helped create that claustrophobic, "we’re all in this together" vibe that translates to the screen.
How to Appreciate the Performances on a Second Watch
When you re-watch 12 Hour Shift, stop looking at the gore. Look at Mandy’s face whenever Regina speaks. It’s a masterclass in internal screaming.
- Pay attention to the background: The nurses and patients who aren't part of the main plot are often doing things that hint at a much larger, equally dysfunctional world.
- Listen to the dialogue pacing: The way Arquette and Bettis trade lines feels like a stage play. It’s snappy.
- Watch the physicality: Chloe Farnworth’s character moves like a toddler who just drank three espressos. It’s a deliberate contrast to Mandy’s heavy-footed exhaustion.
Making Sense of the Chaos
Ultimately, the cast of 12 hour shift succeeded because they didn't play the "joke." They played the stakes. When a character is trying to find a missing organ, they don't act like they're in a dark comedy; they act like their life is over. That’s the secret sauce.

Next Steps for Fans of the Film:
- Check out May (2002) to see Angela Bettis in her breakout horror role.
- Look up the documentary You Cannot Kill David Arquette to see what David was doing around the time this was filmed.
- Follow Brea Grant on social media; she often highlights the specific character actors she uses in her projects.
- Verify the filming locations in Jonesboro, Arkansas, if you're ever on a horror-themed road trip—many of the exterior shots are still recognizable.
The movie works because it knows exactly what it is: a small-scale nightmare fueled by great performances. It’s proof that you don't need a hundred million dollars if you have the right people in the room. Or the right kidneys.
