Here is a disaster flick with an unhappy New Year’s theme.  A luxury cruiser on its final voyage has the misfortune of confronting and ending up on the losing end of an earthquake generated massive tidal wave.  The net effect is that the USS Poseiden is flipped upside down by the wave and as a result everything down is now up and vise versa.  A group of survivors of the initial disaster then mount an effort to find a way to be saved by the eventual rescue crews.  What proceeds from this point is a potboiler of clashing ideologies and personalities and unforeseen ship generated crises.  What great fun!  Gene Hackman leads this merry band as they make their way toward the engine room and meet up with disaster tacked upon disaster.  Also features Ernest Borgnine, Stella Stevens, Red Buttons, Shelley Winters and Roddy McDowall.  It will keep your attention.  Nice special effects.  I guess Airport started the disaster trend in movies in the early 1970’s and this one followed before being joined by Earthquake and more Airport flicks.  Gritty goings on here to be sure.
