In the film "Ida," Anna is a young woman in 1950s Poland. The memory of World War II hovers.
Anna is scheduled to take her vows in the Roman Catholic Church. Then she finds out that she is Ida, a Jew. Her aunt, who will soon commit suicide, leads her through her family's past. That includes their being axed to death by the Christian supposedly protecting them.
Together they strong-arm the murderer to reveal where the bodies are and re-bury the remains in the official family resting place. All this is filmed in black-and-white, recreating the horror of Hilter's madness.
The power of Ida's and her aunt's pain comes through the nun's laconic ways. She is slow to speak. And when she does the rhetoric is simple and direct. For example, after a few hours with her aunt, whom she hadn't even known existed, she asks, "Who are you?"
The lesson from this film for those of us in communications, especially speechwriting, is that less is more. This is an over-communicated era. The more words we can hold back the more effective the public speaker might be. Less is more was the signature trait of a reflective Ronald Regan.
