Let's Be Happy is a Technicolor 1957 British musical film starring Tony Martin, Vera-Ellen and Robert Flemyng and directed by Henry Levin.

Inheriting a few thousand dollars from her Scottish-born grandfather she was looking after in his old age, she decides to travel to Scotland to see her ancestral country.

On the journey by air and train, Jeannie finds herself continuously near Stanley Smith, a brash washing-machine salesman from Idaho.

As he's sorting out her room, the impoverished landowner Lord James MacNairn, who has overheard them talking and believes that she is wealthy, introduces himself.

When Jeannie catches out Stanley in a lie, taking out a red-headed model to dinner instead of her as agreed, she breaks off their friendship and accepts James' attentions.

Stanley still follows her around, with the pretty French redhead in tow, including taking seats right behind James and Jeannie at the ballet, and inviting them to join him and the model in a restaurant.
