ZKJ, which will be aired on Imagine, follows the format of the US show Wipeout.
Twenty-eight celebrity contestants will try to finish an extremely funny and difficult obstacle race, by climbing huge balls and standing on rolling logs, while SRK plays narrator, guru and commentator.
The actor admits that it is tricky to make viewers laugh at other people doing silly things like falling into mud without making a mockery of the contestants.
"I will do my commentary well and hope that people will laugh. I know that sometimes people get offended by what I say. It is possible that this will happen with this show too, and if it does, we will apologise, " he said.
However, SRK has not yet tried the obstacle course which has been set up in Argentina. "I would like to try it.
I will take my children along in January, " he said. He is not worried about comparisons with Khatron Ke Khiladi though both had celebs doing stunts. "There are no snakes and insects here.
KKK is a fantastic show, but in that show, you had to face danger with fear. Here you overcome obstacles with laughter, " he points out.
He also said that this show was about more than physical ability. "There are physically fit and physically very unfit people on the show. But being physically fit will not necessarily mean you win this.
You don't need to be a daredevil, just a madcap. You have to leap before you think.
There's also an element of luck because it is an obstacle course there will be times when certain things go your way and times when they don't. A lot of macho men will make a fool of themselves, " he revealed.
