We laughed like drains at this movie, the drunk pm lying her arse off to keep her job, British mentality ridiculed, out of date tech winning the day, it was the funniest film I've seen for a long while. There are some great practical jokes, and quite a few occasions where you can't help thinking Brutish intelligence might actually be like this. Fab cameo roles for some older British actors, spooky believable plot, British xenophobia mocked ( or was it? :-))and the classic simplicity / sheer incompetent luck beats sophistication against all odds. My strong recommendation is to laugh out loud as soon as you feel the urge, you won't stop for about 90 minutes.
