The Man from U.N.C.L.E.
I'm not usually a big film person, but I enjoyed this a lot. The film is set during the 'Cold War' era, with secret service agents from the U.S. and U.S.S.R., being forced to work together by their organisations. They are attempting to stop a nuclear bomb from being set off. As you could probably guess, there are many moments during the film, in which the two agents clash over how best to deal with a problem. It's quite light hearted too.... Well worth a watch if you get chance!
