　　塞西尔．B．戴米尔执导的这部影片，获得第二十五届奥斯卡最佳影片和最佳电影故事两项大奖。面对电视界的蓬勃发展，饱受威协的电影界，在这届选择了一部足以压倒电视气势的超级豪华大制作，作为这一届的最佳影片得主。故事描述一个在财政上出现问题的马戏团，为了让团员继续作一整季的表演，签下了有着名空中飞人圣巴斯蒂安加盟的演出。这使一心想在新一季成名的女空中飞人哈莉大为不满，另外经理布莱特为了事业一直刻意冷落暗恋他的哈莉。蒂安却因一次表演危险性高的动作发生意外，跌断了一只手而断送了表演前途。同时一名十年前失手杀妻的医生以小丑身份在马戏团里表演，后因火车翻覆而救布莱特，被警察发现。哈莉因此而被感动，于是对布莱特重燃爱火，并负起整顿马戏团表演的工作。查尔顿．赫斯登和康奈尔．威尔德的表演相当不错。

　　Society sleuths Nick and Nora Charles investigate a murder aboard a floating casino.　　Nick and Nora Charles are attending a charity benefit aboard a gambling ship.　　After a murder occurs, suspicion falls on Phil Brant, who had argued with the victim earlier in the evening.　　When Phil and his wife seek help from Nick and Nora, Nick refuses to get involved.　　But when shots are fired outside his own apartment, Nick begins to investigate, and he soon finds himself in a confusing case with numerous suspects.　　Nick and Nora Charles were the ultimate screen couple, husband and wife detectives, always in step and never missing an opportunity to outwit one another as they solved each crime, which they did just in time for the movie's ending.　　Myrna Loy was a fantastic Nora, the ideal wife and considering she made 14 movies with William Powell, she made it look like they were really married.　　The Thin Man movies, all six of them, played more like sophisticated screwball comedies than murder mysteries, and their comic banter enhanced the proceedings.　　Their little wire-haired terrier, Asta, quite often stole the scene as he helped sleuth out the guilty party.　　He was a great little actor and rumor had it that away from the Thin Man movies, Asta was really Skippy.　　However, the six Thin Man movies credit this cute pooch as "Asta."
