Christian Clavier

He is the brother of French film director Stéphane Clavier.
After his high class studies at the Neuilly Lycée Pasteur—though asserted here and there, he never studied at Institut d'Études Politiques de Paris (Sciences Po) —he started his actor career with the comedic theater troupe Splendid, which had hits with films like Les Bronzés font du ski and Le Père Noël est une ordure.
His most notable success without the Splendid group, and by far his biggest hit to date, was in the 1993 film les Visiteurs, where he played a character known as Jacquouille la Fripouille; the character's cry of "Okkkayyy!!" became a popular exclamation after the movie's success.
