One of the most popular films of all time at the British box office, 'I Live In Grosvenor Square' is an enchanting wartime romance and an enduring testament to Anglo-American relations of the era. Anna Neagle stars as Lady Patricia Fairfax, fiancée of Major David Bruce (Rex Harrison) and daughter of the Duke of Exmoor (Robert Morley), who has given over his Grosvenor Square residence for use by American G.Is. In her duties as a W.A.A.F. corporal, Fairfax comes to meet and fall in love with U.S. Air Force sergeant John Patterson (Dean Jagger). So develops an emotionally charged love-triangle, complicated further by the struggles of wartime life.
