Query: An exciting early film about Shanghai in the 1930s.

Like any movie of the period this one has its limitations in terms of acting and "props", nevertheless it conveys quite realistically the sense of "capitalism gone mad" that characterized Shanghai in the run-up to the Japanese incursion of 1937. The young Gene Tierney and Victor Mature are amusing to watch. All in all, an enjoyable rendition of a fascinating period in Chinese histroy when Shanghai was probably the most important city in the Far East, a position that it strives to recapture in the 21st century..
