The Granddaddy of all disaster films!
The Last Voyage I believe marks the beginning of all the disaster films of the late 60's and early 70's.
Airport, Towering Inferno, Poseidon Adventure, Volcano, Earthquake are just a few of this genre that came along later.
Heroic figures, foolish idiots, brave early victims and those who lose their lives just trying to save their own sorry skin are mostly well represent in this film.
If you are remotely interested in seeing what the Ile de France looked like before the Japanese cut it up to make Toyotas, Datsuns and Hondas... then this one is worth watching. Just keep an open mind and don't look for great dialog, a surprise ending or big budget acting. But this movie was actually filmed on one of the most beautiful and more successful Atlantic ocean liners in history!
