I found this movie on Netflix and watched it last weekend. I wanted to see and hear Freya von Moltke, whom I wrote about here. She appears briefly in the linked trailer at the 1 min 14 sec mark. She is interviewed throughout the movie which tells the story of her husband, Helmuth James von Moltke, whom I wrote about here. The movie isn't about him per se but does an excellent job of fitting him into the larger picture of German anti-War resistance at the time.
If you're into that sort of history, give the movie a watch. The Restless Conscience (1992)
