At the very end of the credits there is a message saying "Et pour tous ceux qui lisent les génériques de fin jusqu'au bout : un petit bisou !", meaning "And for all those who read the end credits to the end: a little kiss!"
The end credits feature famous black and white period photos (featuring Richard Nixon, Valéry Giscard d'Estaing, John Paul II, François Mitterrand). In all these photos, Jean Reno is added in the background.
