Le Gendarme et les Extra-terrestres

Louis de Funes and company discover that a flying saucer has landed, and the alien can imitate humans almost perfectly, if you ignore minor details like drinking gasoline, shooting lasers from its eyes and sounding like a hollow metal drum. But then nobody is perfect.

Jacques Tati once said that if he wanted to, he could have made Hulot movies and wound up a millionaire. He offered some titles, including 'Hulot in St. Tropez'. A bunch of standard gags are included, including de Funes dressing up like a nun and riding a bicycle.
