How many passengers died on Poseidon?

Answer 1

The Poseidon Adventure is an American adventure novel by Paul Gallico, released in 1969. It concerns the capsizing of a luxurious ocean liner, the SS Poseidon, due to an undersea earthquake, and the desperate struggles of a handful of survivors to reach the bottom of the liner's hull before the ship sinks.

Hence, no one died in the making of the novel.

Answer 2

The SS Poseidon passengers were more than 6000 people who died and only 57 people survived out of the Poseidon.
