A witty Norman Krasna script distinguishes this airy romantic comedy. Millionairess Dorothy Hunter (Miriam Hopkins) is tired of finding out that her boyfriends love her for her money, and equally weary of losing eligible beaus who don't want to be considered fortune-hunters. That's why she trades identities with her secretary Sylvia (Fay Wray) before embarking on her next romance with Tony Travers (Joel McCrea). This causes numerous complications not only for Dorothy and Tony but for Sylvia, whose own husband Philip (Reginald Denny) is not the most patient of men. The Richest Girl in the World was remade in 1944 as Bride by Mistake, and in 1955 as the Jane Russell musical The French Line.
