I found it very interesting that almost only Hungarian people wrote reviews on this film.
About the film: IMO this is a typical French comedy, with lots of embarrassing and silly but funny situations and decent acting. Belmondo is in top form, the ladies are OK. If you like French comedies this is right up your street.
What makes this movie unforgettable for many of my fellow citizens is the extremely high quality of the Hungarian dubbing. I mean, I watched this film with the original sound and i have to tell you I didn't get half of the pleasure than watching it with the Hungarian voices.( In Hungary films on TV are usually dubbed and the standard of voice acting in the country was top notch for years. It's slowly declining nowadays, though, I'm afraid.)Many Hungarians know the entire script by heart and it's always a good party thing if you quote a line from this film. To us it's just fun.
Like I said earlier this might not be your cup of tea. However, just for the laughs you can watch it on a day when there's not much to do(I wish I had more of them). It's impossible not to -at least- smiley on the lovely character played by Belmondo.
