Ted Turner – whatever happened to him? – produced this compelling documentary series on the Cold War not long after it had finished. (the link is to a page on YouTube listing them all, just click to watch).
It’s not always as balanced as it aims to be, but it uses footage very effectively and the interviewees include presidents and prime ministers.
Try episode 23, The Wall Comes Down – parts of it always make the hairs stand up on the back of my neck. Very momentous, very human.
