BBC One’s latest period drama, The Other Bennet Sister, is stirring up excitement among Jane Austen fans and newcomers alike, as it throws a fresh spotlight on one of literature’s most overlooked heroines. Premiering on Sunday, March 15, 2026, at 8pm, the 10-part series invites viewers to see the world of Pride and Prejudice not through the eyes of the witty and beloved Elizabeth Bennet, but her quieter, seemingly unremarkable sister, Mary.
Adapted from Janice Hadlow’s best-selling novel, the series offers a bold reimagining of Austen’s iconic tale, taking audiences on a journey with Mary as she strives to step out of her sisters’ shadows and forge her own identity. According to Everything Gossip, Mary’s story unfolds across the lavish soirees of London and the breathtaking scenery of the Lake District, as she seeks self-love and independence—two things not easily won in Regency-era England.
At the heart of the series is Ella Bruccoleri, whose nuanced portrayal of Mary Bennet has already garnered praise from critics and colleagues alike. Bruccoleri, known to many as Sister Frances from Call the Midwife and as Miss Barragan in Bridgerton season three, brings fresh depth and humor to a character long relegated to the background. Writer Sarah Quintrell, speaking to Radio Times, described the casting process as a moment of serendipity: “Ella walked in the room, I think she’d been on tape a couple of times, she came in for a final recall, and I was in the room, and it was just like, ‘Oh, there she is.’ And I felt so incredibly blessed to have found someone who got the range, who got the humour, who got the tone. She took things beyond anything that I’d imagined.”
But Bruccoleri isn’t the only familiar face bringing the Bennet family to life. Ruth Jones, celebrated for her roles in Gavin and Stacey and Stella, takes on the formidable Mrs Bennet. This time, however, Mrs Bennet is more than just an anxious matchmaker—she’s “brutal and brilliant,” as Quintrell teases. “Her Mrs Bennet is just a delight to watch – so funny, so brutal and brilliant. I suppose I’m lucky, I got to write Mary’s family. I got to write Mary’s mum and Mary’s sisters, so they’re slightly different to Lizzie’s experience of that same family, and Ruth really took that on. The cast are incredible.”
Richard E Grant, a veteran of film and television whose credits include Gosford Park, Saltburn, and Too Much, steps into the shoes of the sardonic Mr Bennet. His portrayal, as reported by Everything Gossip, brings both wit and a touch of melancholy, as he retreats to his library to escape the chaos of a house full of daughters.
The ensemble cast is rounded out by Indira Varma as the supportive Mrs Gardiner, Richard Coyle as her sensible husband Mr Gardiner, Dónal Finn as the steady Mr Hayward—a new character introduced in Hadlow’s novel—and Laurie Davidson as the impulsive Mr Ryder, another potential suitor for Mary. The supporting cast also features Poppy Gilbert as Lizzy Bennet, Maddie Close as Jane, Molly Wright as Kitty, Grace Hogg-Robinson as Lydia, and Ryan Sampson as Mr Collins.
One of the show’s most intriguing aspects, according to Radio Times, is its decision to reframe the Bennet family dynamic. By centering Mary’s perspective, the series offers a new lens through which to view some of literature’s most famous characters. Quintrell explained, “I got to write Mary’s mum and Mary’s sisters, so they’re slightly different to Lizzie’s experience of that same family.” This shift promises to challenge viewers’ assumptions and breathe new life into Austen’s world.
The production itself was a labor of love for all involved. Quintrell recalled the camaraderie on set: “We would sit under a little tent having our lunch together outside Longbourn, and everyone was sort of mucking in, and we just had a brilliant time. We all sort of fell in love over that period.” She also gave high praise to casting director Kahleen Crawford and her team, saying, “Not only are they brilliant, the cast – I mean, I don’t even know where I would be in my life without Ella Bruccoleri – but they’re also the most unfussy, hard working, just gorgeous, fun people to be around.”
For those eager to dive in, the release schedule is a treat in itself. As of March 15, the first five episodes are available to stream on BBC iPlayer, with the remaining five set to drop on Sunday, March 29, at 6am. This staggered release allows viewers to savor Mary’s journey and the evolving dynamics of the Bennet family. According to Radio Times, “The drama reimagines the world of Pride and Prejudice through the eyes of Mary Bennet – the oft-overlooked middle sister – bringing a fresh perspective to Jane Austen’s iconic story as Mary steps out of the shadows and into her own life.”
The series arrives at a time when Austen adaptations are enjoying a renaissance. In addition to The Other Bennet Sister, a new Netflix adaptation of Pride and Prejudice is slated for release later this year, with Olivia Colman taking on the role of Mrs Bennet. This parallel release underscores the enduring appeal of Austen’s work and the appetite for new interpretations—especially those that give voice to characters previously left in the margins.
As Mary Bennet’s story unfolds on screen, viewers are invited to reconsider what it means to be “unremarkable.” Through Ella Bruccoleri’s sensitive performance, Ruth Jones’s sharp humor, and the ensemble’s heartfelt chemistry, The Other Bennet Sister promises to be more than just another period drama. It’s a story about finding one’s place, daring to be different, and, above all, stepping into the light—even if it means leaving the comfort of the library behind.
With its compelling cast, lush settings, and fresh narrative perspective, The Other Bennet Sister stands poised to capture the imagination of a new generation of Austen enthusiasts and perhaps, finally, give Mary Bennet her long-overdue moment in the spotlight.
