After this movie was released, restaurants were suddenly bombarded with requests for pink champagne.
This was Irene Dunne's favorite among her films. This also happened to be Charles Boyer's favorite among his films as well.
In 1957 director Leo McCarey remade the movie as An Affair to Remember (1957), starring Cary Grant and Deborah Kerr. (Grant and Irene Dunne had previously co-starred in The Awful Truth (1937), which was also directed by McCarey.) The movie was remade a second time as Love Affair (1994), starring Warren Beatty, Annette Bening, and Katharine Hepburn, directed by Glenn Gordon Caron.
Charles Boyer and Irene Dunne were paired again as a romantic couple in When Tomorrow Comes (1939), made the same year as this film. Both films feature a scene where Dunne sings while Boyer plays the piano. Their third and final film collaboration was Together Again (1944).
Astrid Allwyn, who plays Boyer's heiress fiancée, also appeared in the unrelated film Love Affair (1932), starring a young and relatively unknown Humphrey Bogart.
