Forget James Cameron's squally melodrama from 1997. Resist, if you can, the urge to sing the title to the tune of Shalamar's 1982 disco hit. For this 1958 account of the Titanic's iceberg encounter is worthy of your serious consideration. A restrained, nearly austere ensemble drama that manages to intertwine a dozen different stories without tripping up on any of them, it relies on real-life survivor testimony for almost every line and incident, to immensely moving and dignified effect.
