Steve Oram: Oh the desolate place. There’s no contest.

Alice Lowe: We very flippantly put in the script – a really early draft – they go to a desolate place, and we didn’t really know what that meant.

We just went ‘desolate place’. The desolate place was the most horrifically hair-raising place.

Steve Oram: It was the most amazing experience. We went to Honister Pass, on top of a slate quarry so we had to go up in a 4 x 4…

Alice Lowe: …With a plunging mountain by the side…

Steve Oram: …being dragged up in these specialist vehicles…

Alice Lowe:…By guys who work at the mine, who are really tough and stuff.

Steve Oram: Then there was this hurricane thing. A squall of sleet and rain…

Alice Lowe: You can see it in the film.

Steve Oram: We had like 30 second windows of acting, and then we had to go back into the car.

Alice Lowe: The camera was sort of rocking with the effects of this storm basically. People had this traumatic stare in their eyes because they were having to hunker down outside, all day.

People were just frightened.

Steve Oram: Absolutely terrifying.

Ben Wheatley: Yeah, it was tough. But it was kind of exhilarating doing it like that.
