There were a pair of French films that I caught in the late '70s, comedies that I enjoyed a great deal. The first was Un éléphant ça trompe énormément, and it's sequel was Nous irons tous au paradis. Very funny stuff. They were released here in the US as Pardon Mon Affaire and Pardon Mon Affaire, Too, with the first film remade in English as Lady in Red (stealing bits from the second film, as well).
