Some pictures I can watch again-and-again. This is one.
Set in London, it is a romantic, mystery thriller (with comedy elements). It is also a fascinating window on a world now seventy-five years removed. Its pace, plot, acting, and dialog are all excellent.
Robert Montgomery is most charming as a gentleman thief. Elizabeth Allan is exquisitely lovely as his romantic interest. She's somewhat reminiscent of Paula Prentice in looks and manner, and comes across as intelligent, vivacious, wholesome, natural, and honest. (Yum!) Also, Forrester Harvey, as Montgomery's Cockney cab driver stooge, does an excellent turn as comedy relief.
What really sets this movie apart from others, however, is the absolutely amazing chemistry and timing between Montgomery and Allan. I find it a joy to replay their scenes over-and-over to watch the many nuances that occur. It really is a great shame that they never again worked together.
Finally, the villain himself appears to be the evil twin (in dress and features) of the contemporary pulp-magazine hero "The Shadow." Could this just be a coincidence? Naa! I don't think so.
