That movie was filmed near another farmhouse whose owners refused to let them use for the film because it was about adultery! The couple, married for 50+ years, were staunchly opposed so they had to find another farmhouse.
I thought that was pretty cool and wrote the farm owners a letter.
Still haven’t watched that movie. I pretty much despise adultery themes.
Streep and Eastwood were so mismatched and so different from the characters in the book, I doubt anyone cared if they ended up together or not.
