The Gendarme and the Extra-Terrestrials

I saw this movie at the cinema back in the day, and I remember I was slightly disappointed then because there were no actual alien monsters, just humans making metallic noises and stiff movements. However, rewatching it today I'm impressed what a clever little movie this is. Going into a genre which is clearly beyond its budget, arming its heroes only with a bucket of water, it plays virtuously on the classic doppelganger theme. Again and again, aliens and their flying saucer appear, but who will believe the eyewitnesses that they are among us? Cruchot and his team on their 5th mission (of 6 in total) are fighting an amusing battle, dedicated to the max. The flick was definitely better than I remembered it.
