《大军阀》是由李翰祥执导，许冠文、狄娜、胡锦等人主演的一部喜剧片。影片讲述了北洋政府时代鱼肉百姓的军阀头目们的故事 剧情讲述土匪庞大虎因帮助俄国抗击日本而成为北方的大军阀。目不识丁的他却常自命不凡，闹出了不少笑话。当地大旱，求雨不成的他大骂龙王，命令炮兵对龙王爷开炮，结果误撞下雨，他为此沾沾自喜。他审理一强奸案，高白氏因夫死不甘寂寞，勾引小叔子不成，反诬他强奸。庞大虎命两名士兵在公堂上试行强奸，无法得手，于是把诬告的高白氏拉出枪毙。民国18年北伐军统一全国，日本人为破坏中国统一，支持已下野的庞大虎东山再起，不料当年曾被他无端杀死的戏班老板之女兰芳出现，枪杀了这个阴谋卖国的坏蛋。 《大军阀》是李翰祥杂取民国诸多轶闻趣史改编，庞大虎的艺术形象和荒唐事迹可以看做是张宗昌（三不知、轰日求雨、奉继父至孝）、韩复榘（性癖审案，乌龙百出）、孙殿英（盗东陵）三大军阀的集合体，结尾处被枪杀部分应当也有孙传芳（民国奇女子施剑翘报父仇）的痕迹。影片采用折子戏结构，将各种笑料轶事串在一起，虽然松散，但在擅长描摹世情百态、注重细节铺陈的李翰祥执导下，即便放到现在来看，依旧趣味十足。

No list of the screen's comic geniuses would be complete without Michael Hui Kwun-man. He created a hilarious and lovable comic persona that was both uniquely Asian but also universally beloved. This, his first film, not only showcased his incomparable sense of humor but revolutionized Hong Kong comedy. Evoking Chaplin, he plays a warlord in early 20th Century China, but makes the role his own with both laughs and some of the sexiest ladies on the Shaw Brothers lot.
