I came to live in Shepperton in 1960. I thought: the future isn't in the metropolitan areas of London. I want to go out to the new suburbs, near the film studios. This was the England I wanted to write about, because this was the new world that was emerging.
It was a fine cast and lots of fun to make, but they did the damn thing on the cheap. The backdrops had holes in them, and it was shot on the worst film stock.
