For years, The Rookie has captivated audiences with its blend of heart, humor, and high-stakes police drama. But behind the intense action scenes and emotional storylines lies a very different atmosphere — one that, according to star Melissa O’Neil, is far more fun, supportive, and unexpectedly chaotic than fans might imagine.
In a recent interview, O’Neil — who has portrayed Officer Lucy Chen since the show’s debut in 2018 — opened up about what life is truly like behind the scenes of the hit ABC drama. Her candid insights revealed not just the challenges of filming a procedural series, but also the deep camaraderie that makes The Rookie one of the most genuine ensemble casts on television.
A Set Built on Friendship and Laughter
While The Rookie often explores life-or-death moments in Los Angeles policing, O’Neil said the mood on set is surprisingly light. “You’d think we’d be serious all the time, given what we’re filming,” she shared with a laugh. “But honestly, we can’t stop joking between takes. It’s a family. Everyone has each other’s backs.”
O’Neil praised her co-stars, including Nathan Fillion (John Nolan) and Eric Winter (Tim Bradford), for creating a welcoming environment. “Nathan sets the tone — he’s hilarious but professional,” she said. “Eric, on the other hand, keeps things grounded. He’s incredibly focused, but the moment the cameras stop rolling, we’re all teasing each other or cracking up over something that went wrong.”
That mix of professionalism and playfulness, O’Neil explained, keeps the cast connected even during grueling shooting days. “Some of these episodes are intense — long hours, complex stunts, emotional scenes,” she noted. “So, being able to laugh together really helps us keep our energy up and stay close.”
Filming Action Scenes Is No Joke
Despite the fun atmosphere, O’Neil admitted that the work itself can be physically demanding. “People don’t realize how exhausting it can be,” she said. “We’re running, crouching behind cars, filming in full gear under the California sun. Those vests and belts are heavy!”
The actor recalled times when the cast had to do multiple takes of chase sequences or tactical entries, emphasizing how important teamwork becomes in those moments. “When you’re filming something like a raid or a pursuit, it’s not just acting — it’s choreography. Everyone has to hit their marks perfectly for safety reasons,” she explained.
Still, O’Neil said she thrives on the challenge. “It’s one of the best parts of the job. You really feel like a cop for a day,” she said. “There’s a kind of adrenaline rush that comes from doing those scenes — even when you’re completely drenched in sweat afterward.”
On-Screen Chemistry That Comes From Real Bonds
One of The Rookie’s biggest fan obsessions is the chemistry between Lucy Chen and Tim Bradford — affectionately known as “Chenford.” According to O’Neil, that connection works so well on screen because it’s built on mutual trust off screen.
“Eric [Winter] and I have a great working relationship,” O’Neil said. “We talk through every scene, every beat. We both care a lot about making sure Chenford feels real — not just romantic, but emotional and complicated. And I think fans sense that.”
O’Neil revealed that some of their most heartfelt moments are the result of improvisation or shared instinct. “Sometimes we’ll finish a scene and realize we both reacted the same way without even planning it. That’s when you know the chemistry is genuine,” she said.
She also admitted that while fans see the drama, what they don’t see is how hard it is to stay serious while filming emotional scenes. “There are times when we’re supposed to be in this deeply romantic or intense moment, and something random happens — a line fumble, a sound on set — and we just lose it,” O’Neil laughed. “It takes a minute to get back into character.”
The Rookie’s Cast Feels Like a Real Family
What truly surprised fans about O’Neil’s revelation is how deeply connected the Rookie cast has become off screen. “We’re not just co-workers. We hang out outside of filming. We celebrate birthdays, we text constantly, we check in on each other,” she said.
That bond extends beyond the actors. O’Neil praised the crew for their dedication and warmth, saying the production feels like “a small village that runs on mutual respect.” She added, “We all go through the long days together. It’s a collaborative environment, and I think that’s why the show feels so authentic. That teamwork shows up on screen.”
How the Set Mirrors the Show’s Message
One of the reasons O’Neil believes The Rookie continues to resonate with audiences is because the real-life energy behind the scenes mirrors the show’s themes. “At its core, The Rookie is about people learning, growing, and supporting each other through tough situations,” she explained. “And that’s exactly what happens on set. We’re all growing — as actors, as people.”
She went on to say that the sense of camaraderie they’ve built over the years gives the show its heart. “When you spend this much time with the same group, you form real bonds. That’s what makes the emotional moments hit harder — because we’re not faking it. We really care about each other.”
Melissa O’Neil’s Favorite Part of Filming
When asked what she loves most about being part of The Rookie, O’Neil didn’t hesitate. “The people,” she said. “It’s rare to be on a show where everyone genuinely enjoys showing up to work. I’ve learned so much from Nathan, Eric, Alyssa [Diaz], Mekia [Cox], Richard [T. Jones] — everyone. There’s so much talent and kindness on this set.”
She also expressed gratitude for the fans, who continue to support the show season after season. “The fans are incredible. They notice every detail — the character growth, the relationships, the little moments between scenes. Their passion keeps us going.”
Looking Ahead to Season 8
With The Rookie already renewed for Season 8, O’Neil teased that there’s “a lot more to come” for Lucy Chen. “This season pushed her in new ways, and the next one is going to challenge her even more,” she said. “I can’t say much, but I think fans will be proud of where she’s headed.”
Still, O’Neil’s biggest takeaway wasn’t about plot twists or production secrets — it was about gratitude. “I’m lucky,” she said with a smile. “I get to work with people I love, on a show that means something, and tell stories that connect with millions of people. That’s rare. And I don’t take it for granted for a second.”
