Big Little Lies Season 3 Inches Closer to Production

A single day on a Warner Bros. backlot has sent ripples through Monterey fandom: crews shot one short session at The Ranch Lot in California this week, a small but tangible sign that Big Little Lies season three is nudging toward reality. Excitement first. Then questions. Who was there? Who wasn’t? And what does a one-day shoot actually mean?

Variety reports that the session was brief and selective. Merrin Dungey showed up as Detective Adrienne Quinlan, confirming her role will return to the new season. The five women at the heart of the story—Nicole Kidman, Reese Witherspoon, Laura Dern, Zoë Kravitz and Shailene Woodley—did not appear on that day. Producers, it seems, were taking advantage of a confirmed California tax credit rather than staging a full-scale production push.

So, is this the start of principal photography? Not quite. A single-day shoot can be tactical. It buys a production financial momentum and keeps permits, locations and incentives humming while the bigger logistics—actor schedules, writers’ rooms, COVID-aware protocols, call sheets—are hammered out. Hollywood math has rules: California typically requires principal photography to begin within 180 days of a conditional tax-credit allocation; for massive projects with at least $100 million in qualifying spend, that window can stretch to 240 days. The series’ exact approval date hasn’t been disclosed, which keeps the calendar hazy.

The absence of the lead cast isn’t a surprise. HBO has previously acknowledged the headache of syncing five A-list calendars. These are not bit players. They’re producers too, and their plates are full. Still, seeing Merrin Dungey on set matters. Her Detective Adrienne Quinlan was the steady investigative presence in the first two seasons; her return suggests the new chapter will keep a procedural spine even as personal histories unravel.

Another development: Francesca Sloane signed on late summer 2025 to pen the season premiere and join the series as an executive producer alongside David E. Kelley, Nicole Kidman and Reese Witherspoon. New voices tend to shift the tone. They can refresh a show without erasing what made it compelling—sharp female perspectives, secrets that fester, a community that feels both sunlit and combustible.

Fans will likely have to wait until next year for full production to ramp up—HBO hasn’t given a hard start date—so this one-day shoot is the kind of breadcrumb that keeps speculation alive. Is it cautious optimism? Yes. Is it definitive proof that a full season will arrive next spring? Not yet. But it does move the needle in a meaningful way.

If you’ve been waiting to see Monterey’s women back together, that single day on The Ranch Lot is the kind of small, hopeful sign that big things are slowly being set into motion.

Keep an eye on permit filings and studio notices; in the world of prestige TV, the paperwork often whispers the loudest.
