The Movie ends with his most famous speech, in the House of Commons. I saw a documentary that says the HOC was the only place people would have heard it.
Many people claim to remember hearing it, but It was never broadcast over the radio. Not at that time in history anyway.
All these years, like me I'm sure, most people thought that speech was a rally cry for the British citizens.
You gotta be crazy, you gotta have a real need
You gotta sleep on your toes, and when you're on the street
You gotta be able to pick out the easy meat with your eyes closed
And then moving in silently, down wind and out of sight
You gotta strike when the moment is right without thinking
