“The biggest shock was how unscripted everything is,” Dr Amos says.

Maddy says the only time producers intervened was to tell her to announce that she was an actor over breakfast.

She explains she’d already shared this with her fellow contestants when they were waiting to be taken back to the hotel and had taken their mics off.

Matt says there were some moments that were guided by producers.

“Occasionally, people were pulled out and told to go and speak to some other people – it’s natural that they guide you into a position to make good TV.”

“It’s weird at first because there are cameras in your face but after a while, you forget they’re there and producers don’t ever step in,” Harry adds.

“Most rooms also just have cameras in the corner and you have a mic attached to you so sometimes, you don’t see any of the producers until the end of the day when they check in on you.”

Mike Cotton, creative director of the studio that makes The Traitors, explains that there are cameras “dotted around every single room”.

“I’d say there’s probably about 50 or 60 of those throughout the the living space within the castle.”

He says a team of camera operators works in pairs to follow the cast around into different rooms – but at a distance.

At the roundtable, he says the cameras are hidden and some are built into the table itself.

“The contestants can’t see any cameras and that’s to keep them immersed as they can only see each other,” he explains.
