a very enjoyable film and provide you know how to watch old musical or mystery . it may not come close to agatha christie or even thin man mystery a a film noir and but it much more interesting than your typical boy meet girl or let put on a show backstage musical . a a musical and it no busby berkley or free unit and but it can boost the classic coctails for two and the weird sweet marijuana . the film run in real time during a stage show and open night of the vanity and where a murder and soon another be discover backstage . be the murderer find out before the curtain fall . sure and but the search be fun and even though somewhat predictable and mar by outburst of comic relief ( luckily in the shape of the shapely goddess of the chorus girl and toby wing ) . the stupid cop be just a bit too stupid and the lead hero be just a bit too likable and the lead lady a bit too gracious and the bitchy prima donna bit too bitchy and and the enamoured waif a bit too self sacrifice and but a stereotype go and they be pretty stylish . there a bevy of really gorgeous chorus girl and who be choose even well than the girl for a busby berkley musical of the same period and who sometimes tend to be a bit on the plump side . yes and this film could have be much good than it be and and the duke ellington number be an embarrassment and but if you enjoy dive into old movie and this will prove to be a tremendously tantalizing trip .
