C'était un Rendezvous is the creation of the French filmmaker Claude Lelouch in 1976. Using a Mercedes 450SEL early one August morning, Lelouch attached a camera to the bumper of the car and sped through the streets of Paris. (The sounds of a Ferrari 275 GTB were added in post-production.)
He gave the driver a set route from Porte Dauphine, through the Louvre, to the Basilica of Sacre Coeur, which is straight through the heart of Paris. The driver is still unknown to this day, because Lelouch was never able to obtain a permit to close the streets. The driver, who Lelouch told officials was an F1 racer, went over the speed limit and blew off many red lights.
When this film was first shown, Lelouch was arrested, and because of this, the footage has spent many years underground before it began to resurface on DVD a few years ago.
