On the latest episode of The MarshyCast, I’m joined by writer David Eldridge and director Julian Jarrold to talk about ITV’s powerful new drama Betrayal.

From the moment the first episode begins, Betrayal makes it clear this is not a slow burn. David and Julian explain how they wanted to hook the audience immediately, throwing them straight into a world of secrecy, danger and shifting loyalties.

We discuss the show’s outstanding cast, including Shaun Evans, Romola Garai and Zara Ahmadi, and how each performance helps ground the drama in realism. The conversation also explores the show’s focus on Iran and the hidden, underground threats at the heart of the story, and why those themes resonate so strongly today.

Finally, David and Julian unpack the title itself, revealing the layered meaning behind Betrayal and how that idea runs through every relationship in the series.

If you enjoy smart, gripping television and love hearing how complex dramas are built from the ground up, this is a must-listen.
