During the "glass bridge" challenge, all of the shots of contestants falling through the glass trap doors were shot using stunt doubles.
Contestants experienced emotional and physical discomfort during the challenges, with some requiring medical assistance and suffering hypothermia and nerve damage.
The series faced controversy and threatened lawsuits due to the inhumane conditions, such as lack of food and low-calorie meals.
The show's format intentionally created a chaotic and unpredictable situation for the contestants, making it controversial but not too different from other reality series.
The show is a joint production between the UK production companies Studio Lambert from All3Media and The Garden from ITV Studios and the US's subscription streaming service Netflix.
