Far from being historically naive, Plunkett and Macleane is a very cheeky comedy which uses modern touches to bring humour and vibrance to the story. In one hilarious scene modern music is used to turn a ball into a kind of rave. This picture probably conveys more of the spirit of England at that time than any of the tightly corseted period dramas that we see on our small screens. In those days London would no doubt have been (not much different than today) a hive of grime, guts, violence and sex. The best thing to do is to sit back and enjoy the energy,comedy and damn fine performances in this great little britflick. It's not exactly accurate but then this is not what was intended. Give it a go!
