The Island with Bear Grylls kicks off series two this week, and here's just how its filmed.
After claims of fakery over last year's series, Bear has been as transparent as possible about how the show works.
This year's series will see two groups, one male and one female, each spending six weeks alone on two inhabited islands.
Before the show kicked off, Bear and his team prepped the islands to make sure that they both could - in theory - support the contestants for the duration.
This included adding extra wildlife and, in the case of the girls' island, creating a fresh water source.
But Bear insisted that it was still up the Islanders to find these resources and exploit them.
Each of the two groups were also provided with some starting supplies, including three knives, basic fishing equipment, water for their first 24 hours and medical supplies.
The Islanders also both had an emergency satellite phone to contact Bear and his team in case of real problems.
However help, from the show's base on a third island, was still some 20 minutes away in the best case scenario.
When it comes to how The Island is filmed, recording is undertaken completely by the contestants themselves.
Four of the islanders are trained camera operators, although everyone had a go at shooting both with handheld cameras and GoPro cameras attached to them.
The six weeks of footage was then edited to the show that you can watch from Wednesday night on Channel 4, 9PM.
