Jean Smart has joined The Families Stone, the forthcoming follow-up to the 2005 Christmas comedy The Family Stone. The new film brings the Stone family back together two decades after the death of its mother, Sybil, and gives the reunion a distinctly awkward seasonal complication: family patriarch Kelly Stone has invited the woman he has fallen in love with, played by Smart, to Christmas.
The project is set to begin filming in New York in the fall. It is writer-director Tom Bezucha’s return to the family and the emotional terrain established in the first film, which centered on a holiday visit where romantic expectations, family rituals and deeply held judgments collided.
Smart joins a large returning ensemble
Smart joins previously announced cast members Rachel McAdams as Amy Stone, Sarah Jessica Parker as Meredith Morton, Claire Danes as Julie Morton, Dermot Mulroney as Everett Stone, Craig T. Nelson as Kelly Stone, Luke Wilson as Ben Stone, Tyrone Giordano as Thad Stone, Elizabeth Reaser as Susannah Stone, Paul Schneider as Brad Stevenson and Brian White as Patrick Thomas.
That roster matters because the original movie’s identity was inseparable from its ensemble. The Stones were not merely background relatives assembled to react to a visiting character. Their overlapping relationships, loyalties and frictions were the engine of the comedy. Reassembling so many performers therefore suggests the sequel will again treat the family gathering itself as its central setting rather than as a short prelude to a separate plot.
Smart’s character arrives at precisely the kind of fault line that can support that premise. The official setup is not just that Kelly has a guest for Christmas, but that he is presenting a serious new relationship to his adult children after the passing of their mother. In a family story, that makes Smart’s role more consequential than that of a conventional holiday-date character. She represents a change to the group’s understanding of home, memory and who gets to belong in the house.
What the new title and premise signal
The sequel is titled The Families Stone, adding an “ies” to the original title’s singular Family. The supplied premise does not spell out the intended meaning of that shift, so any interpretation remains speculation. Still, the plural wording fits a story in which an established family has to reckon with an additional person and the possibility of a newly formed relationship becoming part of its holiday tradition.
The original The Family Stone followed Meredith Morton, played by Parker, as she visited the Stones with boyfriend Everett, played by Mulroney, for Christmas. Meredith was presented as a conventional businesswoman entering an eccentric, close-knit extended family. A major element of that pressure was an heirloom wedding ring: she had to persuade Everett’s mother that she was worthy of it.
The new film reverses the generational position of the outsider. Rather than focusing on a partner trying to gain acceptance from the parents, the sequel places the father’s new love interest in front of the children and wider family. That change gives the story a built-in perspective on time passing. The people once negotiating parental approval are now confronting their own reactions to their father’s decision.
It also creates room for a holiday-comedy dynamic without diminishing the premise’s emotional stakes. Christmas reunion stories tend to intensify familiar tensions because relatives are put into a shared space with rituals, expectations and little opportunity to avoid difficult subjects. Here, the surprise invitation makes the gathering a test of how the Stones can honor Sybil’s memory while allowing Kelly’s life to move forward.
Sybil’s absence is central to the sequel
Diane Keaton played Stone family matriarch Sybil in the 2005 film. The sequel was first revealed by Bezucha in 2025, shortly after Keaton’s death. Her character’s absence is not being treated as a detail outside the story: the film’s premise explicitly begins 20 years after the mother’s passing.
Bezucha has described working on the film while feeling the loss of Sybil, saying he had spent months imaginatively returning to the family home and missing her there. That framing clarifies why the sequel’s new relationship is potentially more layered than a simple comic disruption. The narrative is built around grief and renewal occurring at the same table, during an occasion traditionally associated with continuity.
There is an important distinction between those two ideas. A story about grief is not automatically a story about refusing change, and a story about a new romance is not automatically a story about replacing someone. The tension in The Families Stone appears designed to come from that conflict: a family can preserve someone’s place in its shared memory while still needing to accept that the survivors’ lives continue.
Why Jean Smart is a consequential addition
Smart is best known recently for leading HBO’s Hacks as Deborah Vance. She won an Emmy for the role in the comedy’s fifth and final season, becoming the first female performer to win an Emmy for every season of one show. Her film credits include Babylon, Wildflower, Senior Moment and Superintelligence.
Those credits establish a performer with substantial comedy experience, but the casting is notable for another reason: the new character has to work in more than one register. Kelly’s partner is the premise’s surprise, which means she may initially be seen through the Stone family’s anxiety and suspicion. Yet the emotional idea of the sequel depends on her being a person rather than simply an obstacle for the returning cast to oppose. Smart’s role sits at the intersection of comic discomfort and a family’s genuine mourning.
That is especially relevant to a sequel arriving 20 years after the original. Nostalgia can bring an audience back to a recognizable house and familiar characters, but it cannot make two decades disappear. The story’s premise acknowledges the passage of time directly instead of asking viewers to pretend that nothing has changed. Smart’s character gives the film a human way to dramatize that change.
What is confirmed—and what is still unknown
Confirmed details are relatively focused: Smart has joined the cast; the returning ensemble includes McAdams, Parker, Danes, Mulroney, Nelson, Wilson, Giordano, Reaser, Schneider and White; Bezucha is writing and directing; and production is expected to begin in New York in the fall.
Also confirmed is the core scenario: the Stone family will reunite for Christmas and encounter Kelly’s unexpected new partner, played by Smart. The provided details do not identify her character’s name, describe individual story arcs for the returning characters, offer a release date or explain how the sequel’s events will unfold after the introduction.
That leaves plenty of practical questions for fans of the first movie, including how the adult Stones’ relationships have evolved and how large a role the broader holiday gathering will play. For now, the clearest expectation is a family ensemble comedy shaped by a more mature conflict than the first film’s courtship-and-approval framework. It is a return built around the same seasonal pressure cooker, but with the family asked to make room for a future that may not look like the past.
