Continuity mistake: When Velvet and her mother are sitting and talking in the attic, her mother pours some gold coins into Velvet's lap. Velvet is sitting back on her feet, but a few seconds later, she raises up on her knees to hug her mother. The coins should go spilling everywhere, but we never see or hear them.
Factual error: As the train with Wilson aboard pulls into a town toward the end of the movie the year is 1919. Through the window of the train, looking out into the parking lot, there are two cars from the mid to late 1930s.
