Cast of The Secret of the Greco Family: Meet the Faces Behind the True-Crime Drama

When a show is based on something that really happened, the cast carries a different kind of weight. You can feel it in the performances the tension, the fear, the strange quiet that follows secrets sitting too long in a family home. The Secret of the Greco Family does exactly that. It takes a real case from the 1980s, places it in a suburban Mexican setting, and lets the truth seep through the cracks of a family that looked ordinary from the outside.

Here’s what matters: the actors didn’t just play roles. They stepped into the lives of real people shaped by control, loyalty, and a hidden world of crime. Getting to know this cast gives you a clearer view of why the series feels so unsettling and so believable.

Cast of The Secret of the Greco Family

The Heart of the Story: Who Plays the Greco Family?

The show follows the Greco clan, a respected family hiding a darker reality. On the surface, they look polished and traditional. Behind closed doors, they run an organized kidnapping operation that destroys everything they touch.

The cast brings this double life into focus with performances that feel grounded and painfully human.

Fernando Colunga as Aquiles Greco

Fernando Colunga, usually known for heroic telenovela roles, takes a sharp turn here. His portrayal of Aquiles the family patriarch shows the creeping authority of a man who believes he’s immune from consequence. He plays Aquiles with a calm certainty, the kind that makes you wonder how many times he’s crossed a moral line without blinking.

His performance carries the entire house. Every room feels colder when he walks in.

Lisa Owen as Marta Greco

Lisa Owen gives Marta a kind of quiet desperation that builds as the story unfolds. She doesn’t shout. She doesn’t fight back in obvious ways. Instead, she holds her family together with the belief that survival sometimes means obedience. Her eyes do most of the talking, especially in scenes where her silence says more than any dialogue could.

Owen makes Marta relatable even when her choices feel impossible.

Manuel Masalva as Andrés Greco

Manuel Masalva plays Andrés, the son who wrestles with loyalty and conscience. He’s trapped between love for his father and the growing horror of their family’s crimes. Masalva brings a restless energy to every scene pacing, hesitating, pulling back at the last second.

You can almost see the battle happening in his mind.

Alejandro de la Madrid as Orestes Greco

Orestes is the brother who doesn’t ask for trouble but finds himself swallowed by it anyway. Alejandro de la Madrid gives him a weary sincerity. His storyline feels like someone trying to escape a life already stitched into his skin.

He’s the character who makes you ask: how much of your family’s choices do you have to carry?

Roberto Uscanga as Tacho Greco

Tacho is the youngest, still learning how to stand in a house full of shadows. Roberto Uscanga plays him with the uncertainty of someone too young to know what loyalty will cost him. His innocence makes the darker moments hit harder.

Is The Secret of the Greco Family Based on a True Story?

Short answer: yes.

The series is inspired by the real Puccio family case in Argentina, a criminal clan responsible for kidnappings and murders during the early 1980s. Netflix adapted the story to a Mexican setting, but the structure remains very close to the truth. The eerie normalcy of a polite, religious, well-respected family running a kidnapping ring comes directly from real events.

That’s why the cast feels so tightly wound. They’re carrying history, not just fiction.

Is The Secret of the Greco Family Worth Watching?

If you like true-crime stories that take their time and let the tension breathe, the answer is yes.

This isn’t a loud show. It’s quiet. Patient. Its power comes from watching characters you’re supposed to trust slowly show you the worst parts of themselves. The cast holds that balance beautifully offering moments of warmth right before everything begins to crumble again.

It’s worth it for the acting alone.

Where Does the Series Take Place?

Though the real case happened in Argentina, the Netflix adaptation sets the story in Mexico during the 1980s. The environment feels calm on the surface quiet neighborhoods, spotless homes, polite social circles. Underneath that calm, you can sense the unease growing with every disappearance.

Mexico’s version of the story adds its own cultural layers, giving the series a rhythm that feels local, familiar, and unsettling at the same time.

Where Is the Greco Family From?

In the show, the Greco family is portrayed as an upper-middle-class Mexican household with strong community respect. People trust them. They attend church. They host dinners. Their world is built on the belief that appearances matter more than truth.

In the real case, the family was from Argentina, but the adaptation keeps the same structure: a well-known family hiding a world no one wants to look at too closely.

Why the Cast Makes the Story Hit Harder

This series works because the actors never lean into exaggeration. They play the Grecos like a family trying to stay normal while standing on a fault line. The tension comes from watching them pretend everything is fine when every scene tells you the opposite.

There’s a strange, gripping humanity in that how fear, loyalty, and power twist together until no one knows where the line is anymore.
