I watched this at home on a DVD set of 7 Clint Eastwood movies from my public library. Seeing this was especially timely because 2017 saw the remake of this movie. Pretty much the same story in each, with minor character changes, with pretty much the same ending.
Having seen both of them within a month I can say this 1971 version is clearly the more interesting movie. Part of that is Eastwood as the injured Union soldier taken in by the ladies and girls of a school in plantation Louisiana. We've seen him in so many action roles we sometimes forget what a good actor he is.
The outdoor scenes were filmed south of Baton Rouge at Belle Helene plantation in Geismar, Louisiana, built in the 1840s. In more recent times, the 1990s, the plantation was bought by Shell Chemical Company and restored. Most interior scenes were filmed on a set in California.
Clint Eastwood is the injured Union soldier, John McBurney, a duplicitous man. By use of brief flashbacks we see that he lies to the ladies about his past. He is a coward and wants to heal and stay at the school as a handyman until the Civil War is over. He ends up leading most of the ladies and older girls on, pretending he loves each one.
Geraldine Page is really good as the school mistress, Martha. As well as Elizabeth Hartman who was the teacher, Edwina. (Tragically Hartman suffered from depression and killed herself not many years later by jumping off a building.) As well as Jo Ann Harris, about 20 during filming, as 17-yr-old vixen Carol, aggressively pursuing McBurney's affections.
This original version of the story is much more sinister and works better than the remake, but the ending is very similar in each.
