The scene where Delia has come to the orphanage to speak with Charlotte, we can see Charlotte's sleeves change from rolled up to down several times within the shot.
Society women such as portrayed here would never have their names printed (on the many invitations and announcements throughout) as "Mrs. Delia ... Mrs. Henrietta" etc. but as "Mrs." before their husbands' names and as long as they remained widows.
At the beginning of the movie, Union Infantry troops are shown gathering to march. The insignia on their hats is crossed rifles. At that time the Infantry insignia was a bugle. They show the correct insignia on Clem's officer hat. In battle scenes some of the troops have the bugle insignia, too.
The song "When Johnny Comes Marching Home" is heard when Charlotte arrives at the train station to meet Clem. The scene takes place in the year 1861 as evident by the date on The Philidephia newspaper announcing Delia's wedding in the opening scene however the song was written and published two years later in 1863.
At about 1:09, when Tina is standing at the staircase after returning from the ball, as Charlotte is eavesdropping, the shadow of a boom mic passes across the carpet, just after Tina says "What sort of things?" This is especially puzzling because there is no further dialogue in the shot and no reason for the mic to follow Tina.
