Celeb SAS show secrets from no rehearsals and banned mobiles to sleep deprivation

ok.co.uk:

We've been hooked on this year's series of Celebrity SAS: Who Dares Wins with the likes ofJames 'Arg' Argent, Danielle Lloyd, Matt Hancock and Montana Brown taking on the gruelling selection test in the jungle.

Keeping them in check with some "firm but fair" words along the way is chief instructor Mark 'Billy' Billingham who has lifted the lid on some behind-the-show secrets.

The hit Channel 4 show kicked off on Tuesday, 26 September and already we've seen the celebrities take on some punishing jungle tasks in an attempt to pass the notoriously difficult SAS Selection test, pushing them both mentally and physically.

Speaking exclusively to OK! chief instructor, Billy, 57 said the show really is as brutal as it's shown, from 24/7 filming, no rehearsals, banned phones and sleep deprivation. 'No script, no rehearsals' Speaking to us about what happens behind the scenes, Billy said: "People turn up and there's a number of things that we're going to push you through, physical, mental, and emotions just like the ethos of the regiment, that's where it comes from. "We build all these tasks and tests they have to do, which we all test anyway so it's safe and good to do, we do all the safety as we would in the regiment, we do it properly. "Once we've done that, that is it - there's no script, no rehearsals, no retakes and it just runs.
