The assistant stage manager of a small-time theatrical company (Polly Browne) is forced to understudy for the leading lady (Rita) at a matinée performance at which an illustrious Hollywood director (Cecil B. DeThrill) is in the audience scouting for actors to be in his latest "all-talking, all-dancing, all-singing" extravaganza. Polly also happens to fall in love with the leading man (Tony) and imagines several fabulous fantasy sequences in which the director is free to exercise his capacity for over-the-top visuals in this charming 1920's era flick. 英国名导演肯罗素以风格强烈著称，但他执导的这部歌舞片却平易近人，热情洋溢。尤其在舞蹈场面的编排上相当别致，由男主角克里斯多夫．盖博亲自编舞，颇有百老汇黄金时代歌舞剧的特色。剧情描述一名电影制片家爱上了一个业余歌舞剧团的演出，整天梦想着要将它拍成电影，因此同一段歌舞却有两种截然不同的表演方式，对比之下颇能彰显电影的幻想空间和造梦魅力。在七十年代极为走红的英国模特儿崔姬饰演剧团女主角，相当逗人喜爱。
