李翰祥作品，许冠文、白小曼、胡锦、张冲主演，《声色犬马》包括“声"、“色"和“犬马"（赌）三段故事，由许冠文一人分饰三角，以麻将馆中的三姑六婆说是非来贯串全篇。鬼马狂想经典搞笑登场。名流人物杰美芳行为怪诞，乱写影评、乱派评马贴士，却躲不起胡锦的挑逗，惨被戏弄。名医吴新紧平素道貌 岸然，一副正人君子样，其实他甚喜拈花惹草，结果被病人余娟娟设局，伙同大狗熊、大胡子勒索，吴妻原来 也背后参与其事，吴新坚偷香的代价，换来人财两空。有江郎者，在澳门赌场输掉老大的四万余元，怕被人追 杀，唯有一走了之，黔驴技穷中，才明白自己名符其实是「江郎才尽」。

《声色犬马》是风月大导李翰祥代表作之一 《声色犬马》与其前作《风流韵事》、《一乐也》等一样，是“软件式"的风流趣剧。许冠文一人分饰三个角色演活大千世界、光怪陆离的人物角色，乐而不淫、却有警世意味。整部片子的结构略 显松散，好在本片细节丰富，每段小故事都有声有色，充满趣味性，看起来不会有沉闷之感。值得一提的是本片女主角白小曼，她本来是李翰祥发掘的新星，但影片还未及上映，她便自杀丧生，死时年仅十八岁，处女作亦变成最后遗作。
