“You set that up in advance, but you don’t know what the outcome will be and so on and so on.

“We had a notion that we were going to build sheds because we had seen on a reccy those little huts,” he continued. “So you work that in and you go, ‘Right, we will build some sheds,’ but what will happen to them or how you know how they will play out, we don’t know.”

In the special, we watch as the Grand Tour trio drive through the snow with sheds on the backs of their cars before driving down a ski slope.

When asked whether producers told Clarkson to push Hammond’s shed down the ski slope, he said: “No, that’s his thought.

“We usually go with a sheet of A4 [paper] with bullet points, which for a 90-minute film, I think is still good to sort of hand-on-heart say we’re still making this s**t up overarchingly.”

Ahead of the show’s premiere, Richard Hammond revealed that there were moments of “real peril” whilst filming The Grand Tour, adding: “Just because you’re doing telly doesn’t mean things can’t go wrong.”
