This film is a perfect example of the Commedia all'Italiana, one of the best films (if not the best) of this genre of which, I can say, it is the quintessence. Directed by Mario Monicelli, one of the best Italian director of that period, it had a huge box-office success. It's one of the most hilarious films I've ever watched.
Five middle aged friends enjoying life and having good time by making pranks, by making a mess out of the established society that, for them, is rather boring. But their behaviors show that something is not right with their life, since being in search of continuous fun is certainly a way to forget one's pain and problems. For this, aside from being funny, it is also bitter-sweet. For the quintet nothing is sacred, anything can be laughed at (also a funeral) and thus it is amorally enjoyable. In short, breaking moral rules with friends, making cruel jokes with them is a medicine against the pain of normal life. Memorable is the scene in which the five friends slap passengers of a train who have their head out of the windows as the train starts moving and thus cannot go down and react anymore.
