The Jump TV series is set for a January 26 start date on Channel 4.
The reality television series follows celebrities as they brave gigantic ski jumps that have been described as dangerous.
Because of the danger, two of the original contestants have already pulled out.
Among those that have stayed in are Richie Neville of reformed boyband 5ive, comedian Marcus Bridgestock, hairdresser Nicky Clark, socialite Henry Conway, ex-cricketer Darren Gough, Olympian Sir Steve Redgrave, presenter Anthea Turner, ex-The Only Way Is Essex cast member Amy Childs, presenter Melinda Messenger, TV presenter Laura Hamilton, singer Sinitta, and ex-Pussycat Doll and presenter Kimberly Wyatt.
Winter Olympics stars skier Graham Bell and skeleton gold medalist Amy Williams are among the people training these celebrities before they make the big jumps.
As the premiere is set for just a day from now, it has been revealed that the show was rejected by ITV two years ago for being too dangerous.
“This show was pitched to us two years ago but in the end we thought the chances of someone famous getting seriously hurt were just too high, so we said no,” an ITV insider told the Daily Mirror.
“How can you safeguard against injury when they’re doing ski jumps like Eddie the Eagle or skidding around in bobsleighs?
“To keep them safe on skis you’d be telling them to snowplough – and scintillating TV that is not.”
A production insider on Channel 4 acknowledged the difficulty, saying: “It’s been a nightmare. Everyone’s getting hurt.”
