The Belle of Broadway

The plot is almost identical to "Fedora," made 52 years later by Billy Wilder, though that film was based on a short story by Tom Tryon. There may be more to this connection than first appears. Wilder based Fedora (1978) on a novella by Tom Tyron. Tyron's story was inspired by the real-life case of silent film actress Corinne Griffith, who in the 1960's claimed in court that she was really a younger replacement in the form of her own sister, younger by 20 years. It is plausible that neither Wilder or Tyron were familiar with The Belle of Broadway, however Griffith was working in Hollywood when this film was made. It is reasonable to assume she had seen the original film, whether she remembered it or not.
