The French Atlantic Affair is a novel by Ernest Lehman which was published in 1977. A 3-part TV miniseries based on the book was produced and broadcast in 1979.
Plot
A luxury ocean liner, the SS Marseilles of the French Atlantic Line, is hijacked by Father Dunleavy, a messianic priest, and his cult followers for a $70 million ransom in gold. Harold Columbine, a novelist, and Charles Girodt, the ship's captain, attempt to save the lives of the passengers, some of whom are also members of the group.

Two young amateur radio enthusiasts are the only link between the ship and the outside world. The SS Marseilles was based on the ocean liner SS France (1961) of the French Line.

In the novel, the hijackers were a group of employees laid off by NASA and its contractors after the termination of the Apollo program. The amateur radio operators were a passenger (not a member of the terrorist group), and his on-shore friend, both of whom were physicians.

The vessel in the novel is called the SS Marseilles and is based upon the French Line's SS France. Interiors were shot on soundstages and in Long Beach, California aboard the RMS Queen Mary. The film also shot on location in Paris and surrounding areas.
