I read an interview with the director, who stated that the subway incident was an amalgam of various interactions between Churchill and the public, but that there is no documentation that the encounter actually occurred. I was also a bit surprised that the movie indicated so much doubt on Churchill’s part, especially about committing to the Dunkirk rescue. I’ve been a fan of Churchill since I was a small child in the ‘50s and have a great CD of his most famous speeches, so I noted that the film seriously reduced his two most famous speeches. Other than that, I was enthralled by the movie.
