Poldark and Harry Potter favourites star in first look at new dark psychological drama

The actors who will star in a new four-episode mystery series on Channel 5 – currently called The Family Secret – have been revealed. Matthew Lewis, known for his role in Harry Potter, and Eleanor Tomlinson, famous from Poldark, will play the lead characters.

I’m so excited! They’ve finally started filming, and we got our first look image (above) of the stars on set! It looks like they’re shooting all over the North East of England, which is fantastic. We’re going to have to wait a little while, though – the series isn’t due out until 2026. I’ve been following this project for a while and can’t wait to see it come to life! More details here.

According to the psychological drama‘s synopsis, it will asks: “What if your past isn’t what you think it is?”

Okay, so the story unfolds with Eleanor Tomlinson taking on the role of Amanda Blakefield. She’s living what seems like a perfect life with her husband, Jimmy – that’s Matthew Lewis – and their son, Luke, who’s brilliantly played by newcomer James Younger. But things take a dramatic turn when Amanda suddenly receives a huge inheritance from a complete stranger – someone she’s never even heard of! It really throws her world into chaos, and I’m already hooked to see what happens next.

Her life falls apart when she gets caught up with the Worrall Family. The family’s leader, Martin Worrall, played by Denis Lawson (known from New Tricks), heads a family haunted by secrets from the past. As Amanda’s investigation takes her deeper into the Northumberland area, she starts to uncover what happened years ago. This discovery completely changes everything for everyone involved.

I’m so excited to see the incredible cast they’ve assembled for this series! We’ll be seeing Rebecca Front (from The Thick of It) and Callum Woodhouse (All Creatures Great and Small) playing Martin’s wife, Fiona, and son, Anthony, respectively. And it’s fantastic news that Stephen Tompkinson (known for DCI Banks) will be portraying farm worker Boots Maddison, alongside Paula Wilcox (from Trying) who’s playing Amanda’s mother, Linda. What a lineup!

Alongside this, Danielle Walters, known from Chewing Gum, stars as Amanda’s close friend Sandy, and Nina Wadia (EastEnders) portrays the solicitor Laura.

Paul Testar, commissioning editor for 5 said in a statement: “The Family Secret explores how easily family relationships can be broken and the far-reaching consequences of secrets that have been hidden for years, featuring a fantastic performance from Eleanor Tomlinson and a strong supporting cast.”

This drama is expected to immediately grab viewers’ attention, and we’re thrilled to collaborate with Lonesome Pine once more, following the positive reception of The Inheritance and The Feud.

Lewis is currently appearing in five dramas, and Murder Before Evensong will begin broadcasting on October 7th.

The Family Secret (w/t) will air on 5.
