根据梅尔．维尔的经典文学名著改编，由老牌导演约翰．休斯顿掌舵，加上格利高里．派克将高傲倔强的艾海伯船长塑造得入木三分，使本片成为海上冒险片的经典佳作。故事以一条全身纯白的巨型鲸鱼莫比敌为中心发展，它是一条被水手们视为魔鬼化身的凶猛鲸鱼。艾海伯在捕捉它的过程中被咬掉了一条腿，这种屈辱与伤痛更激发起他一定要打败这条巨鲸的决心，然而也因他这种偏执狂的意志导致很多无辜船员葬身海底的悲剧。本片的海上历险场面拍得相当壮观，在细腻的心理刻画之外也有不错的娱乐效果。
This classic story by Herman Melville revolves around Captain Ahab and his obsession with a huge whale, Moby Dick. The whale caused the loss of Ahab's leg years before, leaving Ahab to stomp the boards of his ship on a peg leg. Ahab is so crazed by his desire to kill the whale, that he is prepared to sacrifice everything, including his life, the lives of his crew members, and even his ship to find and destroy his nemesis, Moby Dick.
