The Gathering Storm (2002). A most excellent movie about Churchill's 1930's before his return to the Admiralty. Albert Finney is spectacular in his portrayal of the former PM, and the movie is quite precise historically speaking. I am reading the II tome of Churchill's biography by Manchester and I have got to say that many of the episodes described in the book are in the movie - with some dramatization of course. I believe that the full movie is on youtube, I highly recommend it. I also find this movie much superior to The Darkest Hour (2017). One of the reasons I say this is that The Gathering Storm displays Mr. Churchill in his full rudeness, while The Darkest Hour created a couple of episodes (especially one that really bothered me) to make him more likeable. On a side note, in my previous viewings I never noticed that Lena Hadey (aka Cersei Lannister) is in the movie and - dare I say it - quite beautiful in it.
