This is the first French film I ever saw since moving to France from the UK a year ago, and what can I say, nothing else compares to it! I can certainly see why it has become such a classic over here. I've seen it several times now and it still has me in fits of laughter ever time I watch it. I strongly advise everyone to watch the original version and not to bother with the English soundtrack, as the translation is truly atrocious and a lot of the jokes are missed out.
Set in Val d'Isère in the 70s, a group of friends head for the mountains for a skiing trip, and everything that could possibly go wrong on a skiing holiday DOES go wrong... add to that the unique French sense of humour and loads of witty remarks from the characters throughout, and you have a truly superb film. Highly recommended!
