L'avventura del Poseidon

The aging liner Poseidon, on her final journey, is struck by a tidal wave that knocks her upside down. A small group of passengers realise that if they want to survive they must journey up into the bowels of the ship hoping for rescue from above.

The idea is well conceived and the excellent cast turn in good performances despite getting little help from the somewhat corny script. With above average special effects for the time and excellent sets that convincingly realise the upside down half-flooded ship and its bewildering maze of passageways, the movie manages to be compelling and exciting viewing.
