Watch The Poseidon Adventure (1972) Online
A group of passengers led by Gene Hackman's priest and Ernest Borgnine's grizzled cop struggle to escape when their unseaworthy cruise ship is flipped over by a tidal wave. Cresting the wave of Seventies disaster movies, this suspenseful epic really sorts the men from the buoys (... sorry). Look out for Leslie 'Police Squad!' Nielsen as the doomed ship's captain.
