This Man in Paris (1939)

Barnes and Hobson, as an ace reporter and his wife, serve up a nice line in banter while hunting down a gang of counterfeiters in Paris, all under the watchful eye of skinflint newspaper boss Macgregor (Sim). The husband-and-wife team in this snappy comedy was the closest British film came to emulating the success of American series The Thin Man. Hobson, still only 22, had already had a successful stint in Hollywood, but returned to Britain where her career continued to flourish over the next two decades.
