Louis de Funès is by far the best French comedian, one every French or Belgian would be able to name a handful of his movies, so rewatching one of his movies brings back memories from my youth, when back in the days you didn't have much choice. You would watch what was on the telly on the few channels you had, a de Funès movie was always popular. Sur Un Arbre Perché isn't one of the better ones, mostly because of the rather annoying Géraldine Chaplin, daughter of the famous Charlie, and Olivier de Funès, son of Louis, who mostly plays in his father's movies and who never had the same charisma or acting talent as his father. This movie is worth a watch if you're a fan of Louis, otherwise there are much better ones like La Grande Vadrouille for instance.
