Fact for the day: Naturally, in a movie that spotlights Hollywood's use of uncredited singers supplying voice work for its headlining talents, there's an uncredited singer supplying voice work for a headlining talent. As described in The Making of an American Masterpiece, Reynolds' solo performance for "Would You?" and her duet with Kelly on "You Are My Lucky Star" were both dubbed by actress Betty Noyes. Furthermore, in the scene where Reynolds' Kathy Selden is recording the spoken lines to be used by Hagen's screechy Lina Lamont, that's actually Hagen's real voice being used.
