This is nice.
Karl Eccleston and Fiona Pepper are amazingly good actors. The writing is excellent as is the directing. The subtext. THE SUBTEXT IS BRILLIANT.
When I was living with the Efe Pygmies in the Ituri Forest, they would imitate French and English speakers while ranting about specific people who had annoyed or amused them. It was easy to tell which they were doing ... French vs. English. But it only sounded like people imitating people, it didn't sound like the real thing. I remember Sid Caesar doing this as part of his regular routine in several languages, and talking about getting in a cab, say, in Italy, and yelling at the cab driver in fake Italian during the whole ride. Here's an example. But that isn't what Eccleston and Pepper did either.
