You know that feeling when you finish a legal drama and you just need to sit in silence for a minute? That’s exactly what happened when the credits rolled on the third installment of the BBC’s anthology series. While the previous seasons gave us massive names like Ben Whishaw and Sean Bean, the cast of Criminal Justice: A Family Matter had a different kind of energy. It felt more claustrophobic. More intimate. It shifted the lens from the cold, clinical streets of London to the internal, rotting dynamics of a "perfect" family.
Honestly, the brilliance of this season didn't just come from the writing by Peter Moffat. It lived and breathed through the performances. If the actors didn't sell that specific brand of middle-class desperation, the whole thing would have fallen flat. We’ve seen courtroom dramas a million times. We know the tropes. But watching these specific performers navigate the collapse of a household? That’s where the magic—or rather, the tragedy—actually happened.
The Powerhouse Lead: Maxine Peake as Juliet Miller
If you're looking for the heart of the cast of Criminal Justice: A Family Matter, you have to start with Maxine Peake. She plays Juliet Miller. Juliet isn't your typical "heroine." She’s fragile, she’s clearly suffering from deep-seated trauma, and she’s the one holding the knife at the start of the series.
Peake is a legend in British television for a reason. You might remember her from Shameless or The Village, but here, she does something much quieter. There is a specific scene—I think it’s in the first episode—where she’s just standing in her kitchen, and you can see the sheer weight of her marriage pressing down on her shoulders. She doesn't need five pages of dialogue to tell you she's miserable. It’s all in the way she holds her breath.
What makes her performance so compelling is the ambiguity. For a good portion of the show, you aren't actually sure if you should be rooting for her. Did she snap? Was it premeditated? Peake plays Juliet with a sort of vibrating anxiety that makes the audience feel genuinely uncomfortable. It’s masterclass acting. She managed to snag a BAFTA nomination for this role, and frankly, she probably should have won.

Matthew Macfadyen and the Art of Being Terrifyingly Normal
Then we have Joe Miller, played by the incomparable Matthew Macfadyen. Now, most people today know him as Tom Wambsgans from Succession, where he’s sort of a bumbling, power-hungry sycophant. But in the cast of Criminal Justice: A Family Matter, Macfadyen is something entirely different. He is chilling.
He plays a successful barrister. He’s handsome, he’s respected, and he’s a monster behind closed doors. The brilliance of Macfadyen’s portrayal is that he doesn't play Joe as a mustache-twirling villain. He plays him as a man who genuinely believes he is "fixing" his wife. The coercive control is subtle. It’s in the way he comments on her clothes or how he manages the household finances.
It is incredibly difficult to play a character who is both the victim of a stabbing and the perpetrator of psychological abuse. Macfadyen balances this perfectly. You see why the world loves Joe Miller, which makes Juliet's isolation feel that much more devastating. It’s a performance that reminds you that the most dangerous people often have the brightest smiles and the best-tailored suits.
The Supporting Players Who Kept the Tension High
While the leads are the heavy hitters, the rest of the cast of Criminal Justice: A Family Matter is what rounds out the world. You can't have a legal drama without the lawyers, right?

- Alice Sykes as Ella Miller: Playing the daughter in a household defined by abuse is a thankless task, but Sykes nails the confusion of a teenager torn between a father she adores and a mother she doesn't understand. Her testimony is one of the most gut-wrenching moments of the series.
- Sophie Okonedo as Jack: Okonedo is a force of nature. She plays Juliet’s solicitor, and she brings this grounded, weary intelligence to the role. She’s the audience surrogate in many ways—the one person trying to peel back the layers of Juliet’s silence to find the truth.
- Denis Lawson as Bill: As the lead detective, Lawson brings a cynical, old-school grit. He’s not interested in the nuances of domestic abuse; he’s interested in a confession. His scenes provide a stark contrast to the emotional turmoil happening in the Miller home.
The interplay between these characters is what builds the pressure cooker environment. You have the legal team trying to build a defense for a woman who won't speak, and the police trying to close a case that seems open-and-shut. It’s messy. It’s complicated. It’s exactly what good television should be.
Why This Specific Group Worked So Well
There’s a reason people still talk about the cast of Criminal Justice: A Family Matter years after it aired. It’s the chemistry—or lack thereof. The distance between Peake and Macfadyen on screen is palpable. They feel like two people living in completely different realities while sharing the same bed.
The show also avoids the "shiny" look of American legal dramas like Suits. Everything is a bit grey. The lighting is harsh. This helps the actors because they aren't competing with a glamorous aesthetic. They just have to be human. When Juliet is in prison, she looks exhausted. When Jack is working late, you see the bags under her eyes. This commitment to realism is why the performances hit so hard.
Addressing the Darker Themes
Let's get real for a second. This show is about coercive control before that term was even widely used in mainstream conversation. The cast of Criminal Justice: A Family Matter had to portray a type of violence that doesn't always leave bruises.

The legal system portrayed in the show is almost a character itself. It’s rigid. It’s designed for "yes or no" answers in a situation that is entirely "maybe." Seeing how the actors interact with the courtroom setting—the way they shrink or expand in that space—is a fascinating study in power dynamics.
Maxine Peake’s performance, in particular, highlights how the law often fails victims of domestic abuse. Her silence isn't just a plot point; it’s a symptom. The way the other cast members react to that silence—some with frustration, some with empathy—creates a beautiful, tragic tapestry of human error and systemic failure.
Actionable Insights for Fans of the Genre
If you’ve just finished watching or are planning a rewatch because of the incredible cast of Criminal Justice: A Family Matter, here are a few things you should actually do to get the most out of the experience:
- Watch Maxine Peake in Anne: If you want to see her range, her portrayal of Anne Williams in the Hillsborough disaster drama is equally haunting and shows her ability to play resilient, broken women.
- Compare with Season 1: Go back and watch Ben Whishaw in the first season. It’s interesting to see how the show handles a male defendant versus a female defendant in similar legal circumstances.
- Look into the Coercive Control laws: Since this show aired, laws in the UK and elsewhere have changed significantly regarding domestic abuse. Researching how Juliet’s case would be handled today adds a whole new layer of depth to the viewing experience.
- Follow the Producers: Keep an eye on the work of Jane Tranter and Julie Gardner (Bad Wolf). Their eye for casting is legendary—they are the ones who helped bring back Doctor Who and produced His Dark Materials.
The legacy of the cast of Criminal Justice: A Family Matter isn't just that they gave great performances. It’s that they forced a national conversation about what happens behind closed doors in "normal" families. It’s uncomfortable viewing, but it’s essential. The actors didn't just play roles; they gave voice to a type of suffering that, for too long, was kept in the dark.
Watching Macfadyen and Peake face off is like watching a slow-motion car crash. You want to look away, but you can't, because the humanity they bring to the screen is too compelling to ignore. That’s the power of great casting. It turns a script into a mirror.
