He sure was. I read “The Winds of War” and “War and Remembrance” last year, they left such a mark on me. I watched the mini series of both afterward, War and Remembrance was actually filmed in Auschwitz. Read “The Caine Mutiny” in high school, the movie was very good as well.
The War and Remembrance miniseries certainly didn’t pull any punches when it came to the Holocaust scenes.
Arguably it may have been Gielgud’s greatest performance. The scene where he gives the sermon about Job “The Stinking Jew” was poignant.
