Honestly, if you haven't seen Reese Witherspoon stomping across a Monterey beach in a designer trench coat while screaming into a cell phone, have you even lived? It's been nearly a decade since Big Little Lies first landed on HBO, and yet we’re still talking about it. The show didn’t just change the way we look at suburban moms; it completely shifted the trajectory of Reese’s career. Before this, she was the Oscar winner who'd hit a bit of a slump. After? She was a mogul.
Madeline Martha Mackenzie is, in many ways, the "Reesiest" character she’s ever played. She is sharp. She is meddlesome. She is fiercely loyal and deeply, hilariously flawed. But there’s a common mix-up people make online—searching for "Pretty Little Lies Reese Witherspoon" when they actually mean the HBO heavyweight Big Little Lies. It's a fair mistake. Both shows deal with secrets, lies, and a tight-knit group of women, but the stakes in Monterey are a world away from the teen drama of Rosewood.
The Big Little Lies Reese Witherspoon Transformation
When Big Little Lies premiered in 2017, it felt like a lightning strike. Reese didn't just stumble into the role of Madeline; she hunted it down. Along with Nicole Kidman, she optioned Liane Moriarty’s novel before it was even a bestseller. That’s the expert move. They saw the potential in a story about "maternal mischief" and domestic violence when others might have dismissed it as a "mommy book."
Madeline isn't just a character. She's a force of nature. She manages to be both a "Type A" nightmare and the heart of the group. Think back to the scene where she finds out her daughter is moving in with her ex-husband and his yoga-teaching, "neo-hippie" wife Bonnie. Most actors would play that with pure rage. Reese plays it with a quiver in her lip that makes you want to laugh and hug her at the same time.
She's an alpha. But she’s an alpha who feels everything too much. That’s the nuance Reese brings.

Why the "Pretty Little Lies" Confusion Happens
It’s the SEO ghost that haunts the internet. People constantly type "pretty little lies reese witherspoon" into Google. Maybe it’s the alliteration. Maybe it’s the fact that both shows are based on books and feature a central mystery involving a group of women.
- Pretty Little Liars is the Freeform teen soap with "A."
- Big Little Lies is the HBO powerhouse with Meryl Streep.
The difference is night and day, yet the mental overlap persists. If you’re looking for the show where Reese Witherspoon plays a woman who "nurtures her grudges like little pets," you are definitely looking for the Monterey Five, not the girls from Rosewood.
More Than Just a "Mommy" Drama
Let’s be real. In the hands of a lesser producer, this could have been a fluff piece. Instead, Reese and her production company, Hello Sunshine, turned it into a masterclass on female interiority. They took the action from the book's original setting in Sydney, Australia, and dropped it into the misty, high-stakes environment of Monterey, California.
The move was brilliant.

The scenery becomes a character itself—expensive, cold, and slightly dangerous. It’s the perfect backdrop for Madeline’s tightly-wound intensity. There is a specific kind of "worldly weariness" Reese brought to the second season, especially when dealing with her failing marriage to Ed. It wasn't about the "big" lie of the murder anymore; it was about the small, corrosive lies we tell ourselves to keep a family together.
The News You’ve Been Waiting For: Season 3
If you’ve been living under a rock, here’s the latest update. As of late 2025 and heading into 2026, Season 3 is officially happening. Reese herself confirmed it on The Tonight Show, joking that "it's been a minute" since the gang was together. The cool part? The "kids" from the first season, like Iain Armitage and Kathryn Newton, are now actual teenagers. Liane Moriarty is reportedly writing a sequel novel that will serve as the blueprint, focusing on the women as parents of teens.
Imagine Madeline Mackenzie dealing with a teenager who is even more stubborn than she is. It’s going to be glorious.
Why This Role Matters in 2026
We live in an era where everyone is trying to look perfect on Instagram, but Big Little Lies shows the rot behind the white picket fence. Reese’s performance as Madeline reminds us that being "okay" is often a performance. She paved the way for shows like The White Lotus or Succession by proving that we love watching rich people fall apart, provided the acting is top-tier.

Reese once said that Madeline "picked her." She didn't want to play the "nice" one. She wanted to play the one who throws a temper tantrum in a parking lot. That honesty is why the show has staying power. It doesn't judge these women for their flaws; it celebrates their survival.
Your Monterey Rewatch Checklist
If you're going back to watch before Season 3 drops, pay attention to these specific Reese moments. They are the "expert" details most casual viewers miss:
- The "Cancer" Line: When Madeline says she’d be willing to get cancer just to make her daughter stay. It’s the peak of her neurotic, desperate love.
- The Wardrobe: Notice how Madeline’s clothes get more structured as her life spins out of control. It’s her armor.
- The Relationship with Celeste: It’s one of the few depictions of female friendship that feels truly equal. Neither is the "lead"; they are two sides of the same coin.
The legacy of Big Little Lies isn't just the Emmys or the "Who-Dunnit" mystery. It's the fact that Reese Witherspoon took a role that could have been a caricature and made her the most relatable person on television. Whether you call it Pretty Little Lies or get the name right, the impact remains the same.
To prep for the upcoming season, your best move is to revisit the original Liane Moriarty novel. It offers a different perspective on the characters—specifically the Australian setting—that helps you appreciate the creative choices Reese and Nicole made for the HBO adaptation. Keep an eye on trade publications like Deadline for the official Season 3 filming start dates, which are rumored for later this year.
