This is fabulously well done. A kind of Chariots of Fire for science. Tennant is a much better Dr here than ever he was in Dr Who: Both he and Andy Serkis (Gollum) are perfectly cast. I feared in the opening minutes they were going to try an dumb down Einstein to make him "accessible", but no: He's here is all his magnificence, emotional, as well as mental.
Suspenseful and sophisticated, the skilled writing and direction do a grant job of showing, too quote Blake, "the world in a grain of sand, and eternity in an hour". This story, and once personal and universal, takes us from Africa and transit of Venus, to England at her green and pleasant best, the tragedy of Europe's "civil war", Jewish history in Germany, Germans in England, and the dawning of the 20th C. Eddington's honour and grace ("The pursuit of truth in science transcends national boundaries. It takes us beyond anger and hatred and fear. It is the best of us."), Einstein's playfullness, humanity, and stunning intellectual breakthrough, Lodges dogmatism - doggedly defending Newton and the aether - his patriotism, the Jewish Haber, working on chlorine gas for the fatherland - a story in its own right... So much more.
The ensemble cast let their character's character shine through (what a great story that has Fritz Haber, Max Plank, and Oliver Lodge as co-stars!)
