At the end, just before Alexandra leaves Regina, when Regina climbs the stairs and asks Zan if she would "like to sleep in her room tonight", there is a chair in the background (which earlier Regina had been sitting in). There is nothing on the chair. Two shots later, when Alexandra goes to collect her hat and coat to leave, they are on the chair.
When Regina returns home to find Horace in her part of the house, she takes her left glove off before walking towards the staircase. Seconds later, after Horace tells her about the investment in the cotton mill, she turns around at the bottom of the staircase and takes her left glove off again.
When Zan is getting her hair washed, it is much shorter than it is when it is dry and styled.
On the night before Alexandria leaves for Baltimore, she leans over the railing after Aunt Birdie is slapped. In the wide, shot her right hand is about 20 inches from the column, then in the closeup, her hand is just inches from the column.
The film is set in 1900. Oscar Hubbard is reading a newspaper that contains an article about a P.G.A. Match Play tournament. The P.G.A. was not founded until 1916.
(at around 5 mins) When the piano is played, the sounds heard are an octave lower than the hand-positions shown.
At the end of the film, Regina successfully blackmails her two brothers and nephew over the issue of the "borrowed" bonds, noting that with Horace's death they could not rely on his commitment to say the bonds were borrowed, and not stolen, as they in fact had been. In actuality, Regina had no proof that the bonds had indeed been stolen and that Horace did not in fact agree to lend out the bonds as collateral to his relatives. She was blowing hot air and that should have been apparent.
