London by Night (1937) was a B movie, set in London (read: back lot of MGM) and starring George Murphy, Virginia Field, Rita Johnson, Leo G. Carroll, George Zucco, Montagu Love, and Corky. This film is actually based on a play that was never produced.
Murphy plays Michel Denis, a newspaperman in London who, in the morning, is leaving for a vacation in Paris. He and his buddy, a dog named Jones, decide to stay in London, however, to help solve a series of murders by a man carrying an umbrella.
Along the way, he meets a pretty socialite (Johnson), who lives in a house that includes her father (Zucco) and a butler (Carroll).
The atmosphere is captured with lots of fog and some dreadful Cockney, the worst offender being the usually likable Virginia Field. She overdid her role as a barmaid big time.
George Murphy was an actor of terrific charm, and he brings it on here. The dog who plays his dog, Corky, is terrific.
Pleasant.
