I Live in Grosvenor Square

I Live in Grosvenor Square is a British comedy-drama romance war film directed and produced by Herbert Wilcox. It was the first of Wilcox's "London films" collaboration with his wife, actress Anna Neagle. Her co-stars were Dean Jagger and Rex Harrison. The plot is set in a context of US-British wartime co-operation, and displays icons of popular music with the purpose of harmonising relationships on both sides of the Atlantic. An edited version was distributed in the United States, with two additional scenes filmed in Hollywood, under the title A Yank in London.
