Filmed on a Greek island in 40-degree heat, Freddie Highmore and Keeley Hawes shared how they stayed cool (with a surprising Coca-Cola addiction), built instant chemistry, and navigated the show’s emotional core. Both stars also served as executive producers and opened up about shaping the series from script to screen.

Sam Bateman sat down with the cast to discuss the thriller’s sharp pace, Keeley’s unexpected stunt work in episode two, and how their Aquarian connection somehow helped it all flow. Their admiration for one another was clear, and their dynamic off-screen reflects the trust and intensity of their characters on-screen.

And in our second chat, Shalom and Devon broke down their fiery sibling dynamic in the show. From imaginary Spotify playlists (yes, Jason Derulo makes an appearance) to on-set honesty and emotional support, the pair brought humour and heart to their conversation.

Shalom opened up about playing vulnerability against Kayla’s strength, while Devon revealed this was the most instinctive, off-the-cuff role he’s ever played. A standout moment? Shalom once cried off-camera to help boost Devon’s performance — a testament to their deep trust as scene partners.
