Thunder in the City

Edward G. Robinson is an American ad executive whose barnstorming style is judged to be too flamboyant, so he travels to England to learn restraint and dignity. While visiting with his aristocratic relatives, he falls for Luli Deste, the daughter of destitute Duke Nigel Bruce. Bruce owns a mine in Rhodesia that's rich is the miraculous mineral magnalite, so Robinson maneuvers to buy it out from under the nose of banker and romantic rival Ralph Richardson. Lacking the money to follow through with his promised purchase price, Robinson engages in a flamboyant campaign to push magnalite to the British public and recruit investors in his mine. An agreeable if pretty slight romantic comedy that sees Robinson escaping his tough guy persona, ably supported by a top notch British cast.
