Niamh Algar, Fanny Ardant lead AI thriller Harmonia as filming starts in Greece
Cameras are rolling in Athens on Harmonia, a six-episode psychological thriller starring Niamh Algar and Fanny Ardant.
The series is set inside a high-end luxury resort and wellness facility controlled by artificial intelligence. The AI watches everything.
Algar plays Shona Casey, the creator of the AI system. Ardant plays the resort's former owner. Chloe Lea plays a young member of staff who becomes the object of the AI's obsession, as reported by Deadline.
That puts three women at the centre of the story. One built the system. One used to own the building. One works there now.
The wider cast mixes British and Greek actors. Oliver Chris, Abubakar Salim, Goran Bogdan, Theo Augier and George Ioannides are all confirmed. They are joined by Pygmalion Dadakaridis, Konstantinos Zografos, Antigoni Frida and Zoe-Stella Nikolaou.
Behind the camera, Harmonia was created by Peter Carlton, Lefteris Charitos, Amanda Livanou and Hanna Jameson. Charitos directs all six episodes, which keeps one visual hand on the whole series. Jameson is lead writer, meaning she sets the story and tone, with further episodes from Alki Papastathopoulos and Panayotis Christopoulos.
The show is a UK-Greek co-production, meaning companies from both countries are making it together. It comes from Warp Films, ITV Studios and Greek broadcaster ERT. It is described as a predominantly English-language production made with Neda Film, so most dialogue will be in English despite the Greek shoot and partners.
Filming is now under way on location in Greece, including at the Cape Sounio resort and Kapa2 Studios in Athens, according to ITV. The start of the shoot was announced on 7 October, with further trade coverage confirming production on 8 October 2026.
Harmonia is scheduled to launch in 2027. ITV Studios is producing in association with the project and handling international distribution, meaning sales of the series to broadcasters and platforms outside its home markets. The series is co-financed by ITV Studios and ERT, with development support from the Hellenic Film and Audiovisual Fund and Creative Europe Media.
For viewers, this means a wait. The team must finish the Athens shoot, complete editing and post-production, and confirm where the show will air in each territory. A six-part run is a familiar shape for thriller drama in Britain and internationally, built to be watched across six weeks or in one sitting, depending on how the eventual broadcaster schedules it.
