Thunder in the City (1937)

Edward G. Robinson is a successful advertising executive - but his methods prove just a little too much for his bosses, so they send him to their British office where he quickly engages with the "Duke" (Nigel Bruce) and his "Duchess" (Constance Collier) and is soon knee deep in a cunning plan to exploit some ostensibly worthless land owned by the penniless aristocrat - but land that contains the wonder metal "mangalite" - a substance that could make them all gazilionaires. He is not the only one after this, though - he has to compete with the shrewd "Manningdale" (Ralph Richardson). Bruce steals this for me - his appearances are infrequent, but his bumbling decency is the perfect foil for the brash American and the story has an uplifting feel to it. The production is a bit basic, and it does play a little too much to stereotype - but it's still an enjoyable outing for all concerned that is well worth a watch.
