Genre of Four Lions may be called "black", i.e. black humour or black comedy. In contrast? the idea of movie is associated with a real social threat. The holy war of Moslems against infidels continues to possess with some minds of them and even Europeans converted into this faith. Cristopher Morris? scripted and directed this movie, interpretes the idea how a few friends brought together by Barry(Nigel Lindsay) chose a path of false righteousness and a fast way to heaven. No doubt, its a transformation from a talk to an action in form of trips to Pakistan for meeting mujahedins, for becoming holy warriors and assembling exposives. In movie, many of what you can see on the screen and read at news, parody real events. Those who really suffer from clandestine activities are friends and their families. It is important that Four Lions isnt any sort of stereotypes. I strongly recommend it you in order to develop your feelings of reality through the lens of objectivity. I hope youll get more out of this movie observing seriousness hidden under the shadow of comedy.
