The Anglo-American co-production Britannia Mews was released in the U.S. as The Affairs of Adelaide, then reissued as Forbidden Street, the title it carries today. Set in the Victoria era, the film focuses upon Adelaide (Maureen O'Hara), a young lady of good family who renounces both name and fame when she marries an impoverished artist (Dana Andrews). When her husband is killed in an accident, Adelaide is blackmailed by a spiteful old hag (Dame Sybil Thorndike) who claims that the girl killed her spouse. Enter a handsome young barrister who is the living image of Adelaide's late husband (and who, accordingly, is also played by Dana Andrews). He extricates Adelaide from her plight, reunites her with her family, and along the way falls in love with her himself. Ring Lardner Jr. adapted Britannia Mews from a novel by Margery Sharp.
