80s french movie. A man realises he is immortal

Louis is 50 years old, but he is very afraid of aging, so he finds a "miraculous" way to slow it down.

A professional race-car driver discovers that there are certain properties in his blood that will make him, basically, immortal. A dying multi-millionaire also finds out about the racer's blood, and is determined to get it to keep himself alive. This pilot film preceded the later TV series.

An old man on his deathbed seeks peace with his imminent fate through an old film reel of his father.

Two eccentric scientists struggle to create eternal youth in a world they call “blind to the tragedy of old age.” As they battle their own aging and suffer the losses of loved ones, their scientific journeys ultimately become personal.

A French-Greek co-production, filmed in Paris, in which the forty-year-old Maxim is released from prison after five years in prison. As he tries to adjust to life on the outside, he accidentally meets a Parisian taxi-driver who commits suicide right before his eyes. Without a pause he takes the dead cabbie's place behind the wheel and starts making the rounds of the city, transporting passengers (Jean-Pierre Léaud plays the role of a client who recites Cavafy throughout the entire ride). He feels the air of freedom, a lord of Paris and master of himself, up to the moment that he meets young Anies, and his life falls into new paths. In the end, he takes off, destination unknown.
