I Live in Grosvenor Square is better known by its American release title, A Yank in London. Anna Neagle, whose husband Herbert Wilcox produced and directed the film, stars as Lady Patricia Fairfax, who enters into a brief wartime romance with American air force sergeant John Patterson (Dean Jagger). The plot proper is based on a true WW II incident, wherein an Air Corps crew deliberately sacrificed their lives to save an English village of no strategic importance. The multinational supporting cast includes Rex Harrison, Robert Morley, Jane Darwell, and real-life American PFC Elliot Arluck. At the time of its release, I Live in Grosvenor Square was praised for the authenticity of its settings and characterizations.
