The Good Daughter Peacock Cast: Who Plays Sam and Charlie Quinn

Quick answer: The Good Daughter is streaming now: all episodes arrived on Peacock on November 12, 2026, with Sky and NOW carrying it in the UK. Rose Byrne plays Samantha "Sam" Quinn and Meghann Fahy plays Charlotte "Charlie" Quinn, with Brendan Gleeson as their father, Rusty.

The Good Daughter is a crime thriller limited series based on Karin Slaughter’s novel of the same name, and its cast is the main reason people are searching for it today. Below is who plays whom, where you can watch it, and what is still unclear, as of November 12, 2026.

Who is in the cast of The Good Daughter on Peacock?

NBCUniversal’s announcement for the November 12 premiere lists the following main cast. Sky’s own listing for the UK release names the same actors and roles.

The two young actors matter because the story is told across two timelines, so the sisters appear both as adults and as teenagers. We only list roles that both Peacock’s parent NBCUniversal and Sky publish, so smaller supporting parts are left out until they are officially confirmed.

Who are the main characters in The Good Daughter?

The Quinn family sits at the center. Sam and Charlie are the two sisters whose bond drives the story, and Rusty is their father, a lawyer, which is why Charlie’s own career in law matters to the plot. Harriet, known as Gamma, is the family matriarch. Lenore and Ben are named in the cast lists, but neither Peacock nor Sky explains their place in the story, so we do not guess. Reading the novel’s synopsis is not a substitute for the series, and the adaptation may change details, so we stick to what the networks state.

Sky spells the young Charlie actor’s name as Drew Ann Cheek, while NBCUniversal writes Drew Cheek. We use the NBCUniversal spelling.

When did The Good Daughter premiere and where can you watch it?

The series premiered on Thursday, November 12, 2026. NBCUniversal says all of the episodes premiere that day on Peacock, so there is no weekly wait.

A Broadcast headline says HBO Max and Stan have also taken the series for further territories. Check your local service, since we have not confirmed exact dates for those regions.

How many episodes does The Good Daughter have?

This is where sources differ. NBCUniversal says Karin Slaughter wrote all six episodes in her screenwriting debut, and that is the figure we trust because it comes from the producer’s own network. Sky’s UK page, however, says eight episodes are planned for the first season. Until one side corrects the other, treat six as Peacock’s count and note that a UK listing shows a different number. No second season has been announced.

What is The Good Daughter about?

According to Sky’s announcement, the story follows sisters Samantha and Charlotte Quinn, who have spent years rebuilding their lives after a night of violence that marked their family. When another attack hits their hometown of Pikeville, Charlotte, a lawyer like her father, is the first witness on the scene. The case drags up painful memories and buried secrets, and the series explores family ties and the bond between the sisters.

That is all the official material says about the plot, and we do not add detail beyond it. The series deals with violent crime, so expect a dark, serious tone rather than a light mystery.

Who made The Good Daughter?

Sky’s announcement lists the key people behind the camera:

• Writer and executive producer: Karin Slaughter, who adapted her own novel
• Director and executive producer: Steph Green
• Production companies: Made Up Stories, in partnership with Fifth Season, which also handles global distribution
• Executive producers for Made Up Stories: Bruna Papandrea, Steve Hutensky and Casey Haver, alongside Rose Byrne

Byrne therefore both stars and executive produces.

Is there an official trailer for The Good Daughter?

Yes. Peacock published the official trailer on its own YouTube channel, and you can watch it below. NBCUniversal describes the series as told across two timelines, and the trailer is the quickest way to see the adult and young versions of the sisters side by side. Peacock’s channel is the only place we link for video, since re-uploads of trailers are common and often not official.

Is The Good Daughter based on a book?

Yes. It adapts Karin Slaughter’s bestselling novel of the same name, and Slaughter wrote the screenplay herself, with this series marking her screenwriting debut according to NBCUniversal. That direct involvement is a notable detail for fans of the book, since the author controls the adaptation rather than handing it to another writer. Whether the ending follows the novel exactly has not been stated, and we avoid spoilers here.

Why is everyone searching for the cast now?

A cast-led thriller that drops all episodes on one day sends people searching immediately for who is who, especially with two lead actors known from other hit series. Google Trends in the UK listed "the good daughter cast" among its rising entertainment searches on the day of the premiere. We have not watched it for this article and do not rate it here.

What to watch next

If you are planning your week of viewing, our November 2026 movies and TV release calendar lists the other big premieres. For more dramas with confirmed dates, see our guides to Trinity on Netflix (December 1), The Altruists (November 19) and The Pitt Season 3. If you prefer one sitting, a limited series released all at once like this one is easy to finish over a weekend, but spoilers spread fast on social media, so mute the title if you plan to wait.

What we still do not know

Open questions as of November 12, 2026: the final episode count in the UK, the per-episode runtime, and whether the story will continue beyond this limited series. We will update this page when Peacock or Sky clarify.
