影片描绘的是登陆诺曼底的第一天所发生的事件，所谓最长的一天是该片分别从盟军和德军双方面的角度同时描述诺曼第登陆这一历史战役的来龙去脉，以及双方在此期间的重要反应，手法平实，场面逼真，让整个事件在观众眼前重现。并且粗中有细，无论是决策的将军还是登陆的士兵都写得栩栩如生：英军战机低空飞过攻击；美国特种部队遭德军射击；一群法国修女冒着枪林弹雨抢救联军伤兵……备战实况规模之伟大，叫人印象深刻；过程中做出的种种错误决定及各项导致这场历史上其中一场最浩大战争的大小事件，影响深远。

该片细腻且深刻地描写出各类神秘的双面间谍的故事，书中复杂的斗智活动、两难的道德处境、暧昧的善恶定义、纠结的人际关系，情节引人入胜，内容富含人生哲理。
