I liked the Darkest Hour so much that I went to Amazon and purchased two DVD’s on Churchill covering the same period.
It was great to have the foundation prior to watching Dunkirk.
The thing that was left out of Darkest Hour that I have been researching for many years relating to leaders who guide us through troubling times, such as Abraham Lincoln, was Churchill’s Black Dog. He always referred to his deep dark periods of depression as his Black Dog. I have an excellent book just on “Churchill’s Black Dog.”
Lincoln had the same deep dark periods of depression.
Lincoln, Churchill, Mark Twain, and many others used humor as an escape and cover for their dark periods.
Add to the list JFK, Martin Luther King Jr., Ghandi...... all had severe depression. MLK Jr actually tried committing suicide twice.
