Before the film moves to North Korea, there’s a long-ish opening act in which the excesses of celebrity-driven journalism are lavishly and mercilessly sent up, and it would be a mistake to think the two parts aren’t connected. American culture, and particularly trash culture – of which The Interview is very self-consciously a part – is better at slipping over international borders than the SAS. So the idea that it might not only infiltrate a dictatorship but overthrow one has a certain scorched poetry to it.
