When My Fault (Culpa Mía) dropped on Prime Video back in 2023, it didn't just trend; it basically broke the platform's records for non-English originals. People were obsessed. And honestly, while the "forbidden" stepbrother trope and the street racing scenes were high-octane, it was the chemistry of the cast of My Fault film that kept everyone hitting "play."
There is a weird vibe when you talk about this movie. Critics mostly hated it. But the fans? They saw something different. They saw Nicole Wallace and Gabriel Guevara and decided they were the next big thing in Spanish cinema. By now, in 2026, we’ve seen the full trilogy play out with Your Fault and Our Fault, and even an English remake called My Fault: London. But looking back at that original 2023 cast, there’s a lot more going on than just pretty faces in fast cars.
The Electric Duo: Nicole Wallace and Gabriel Guevara
You can't talk about this movie without starting with Nicole Wallace. She plays Noah, the 17-year-old who gets dragged into a world of luxury and illegal races when her mom marries a billionaire. Nicole wasn't some random find. Before she was Noah, she was actually in the Spanish version of Skam (Skam España).
Funny enough, she wasn't the only one.

Gabriel Guevara, who plays the brooding, rich-kid-with-a-secret-life Nick Leister, was also in Skam España. In fact, he, Nicole, and Lucas Nabor (who plays Mario in the film) all worked on that show together. That’s probably why their chemistry felt so lived-in. Gabriel has this way of playing Nick where he’s incredibly annoying one second and then surprisingly vulnerable the next. He’s been busy since the first film, appearing in projects like HIT and Bosé, though his career hit some real-world turbulence in late 2023 following an arrest in Venice (later resolved, but it was a whole thing for a while).
The Parents: More Than Just Background Noise
Most teen dramas treat the parents like cardboard cutouts. My Fault tries a bit harder. Marta Hazas plays Rafaella, Noah’s mom. If she looks familiar, it’s because she’s a huge deal in Spain—you’ve likely seen her in Velvet or The Boarding School. She brings a certain "trying too hard to be happy" energy to Rafaella that makes the tension at home feel real.
Then you have Iván Sánchez as William Leister. He’s the billionaire stepdad who seems perfect on paper but is clearly drowning in his son’s drama. Sánchez is a veteran of the telenovela world and Spanish dramas like Hospital Central. He plays William with a quiet authority that contrasts perfectly with Gabriel Guevara’s explosive performance as Nick.

The Supporting Crew and the Villains
The world of My Fault is populated by a bunch of characters who either want to help Noah or ruin her life.
- Eva Ruiz as Jenna: Every protagonist needs a best friend who knows the "cool" spots. Jenna is that person for Noah. Interestingly, this was a massive breakout for Eva, who is also a singer.
- Víctor Varona as Lion: He’s Nick’s friend and Jenna’s love interest. Varona brings a lighter, more stable energy to a movie that is otherwise filled with people making terrible life choices.
- Fran Berenguer as Ronnie: Every story needs a physical threat, and Ronnie is the street-racing antagonist who basically exists to make Nick look like the "good" bad boy.
- Iván Massagué as Jonás: This is where things get dark. Massagué plays Noah’s biological father. He’s a terrifying presence in the film, representing the trauma Noah is trying to escape. Massagué is a fantastic actor—you might recognize him from the lead role in the Netflix hit The Platform. Seeing him go from that to a villain here shows his range.
Why This Cast Worked When Others Failed
Honestly, if you put two actors with zero chemistry in these roles, My Fault would have been a disaster. The script is... well, it’s based on a Wattpad story. It’s supposed to be dramatic and a little over-the-top. But Wallace and Guevara sell the "we hate that we love each other" angle so well that you almost forget how problematic the setup is.
By the time we got to the 2025/2026 releases of the sequels, the cast had clearly grown up. Nicole Wallace mentioned in interviews for the final film, Our Fault, that she felt much more confident in her voice as an actress by the end of the trilogy. She was 22 by the time the story wrapped, a far cry from the teenager who first stepped onto the set in Marbella.

What’s Next for the Cast?
Since the Culpables trilogy has officially concluded, the cast is moving into different lanes. Nicole Wallace is currently being eyed for more international projects, while Gabriel Guevara has stayed busy in the Spanish TV circuit.
If you’re a fan of the original cast of My Fault film, you should check out these specific projects to see their range:
- Nicole Wallace in Ni una más (Raising Voices) on Netflix—it's a much heavier, more serious role than Noah.
- Gabriel Guevara in From Tomorrow (Desde el mañana) on Disney+, where he plays a lead role.
- Iván Massagué in The Platform (El Hoyo) if you want to see the "villain" play a desperate hero.
The legacy of the film isn't just the millions of views. It’s how it launched a new generation of Spanish stars into the global spotlight. Whether you love the story or find it "trashy," you can't deny the talent involved.
Actionable Insight: If you're looking to follow the cast's journey beyond the films, the best place to start is their Instagram profiles, where they are notoriously active with behind-the-scenes content. Additionally, for those who haven't seen it, the English remake My Fault: London offers a fascinating comparison in how different actors (Asha Banks and Matthew Broome) handle the same characters with a British twist. It’s worth a watch just to see how much the original Spanish cast's "spark" actually carried the first movie.
